SwiftUI Just Turned Seven. Hacker News Is Having the Itch.
SwiftUI shipped in 2019 and just hit its seven-year mark, and a viral Hacker News thread (plus pieces from Yakov Manshin and John Gruber) is relitigating whether it ever grew up. I've built a real app in it for months — here's where my own bugs match the complaints, and where they don't.
Apple Just Added an Eviction Clause to the App Store Lease
Apple's June 2026 App Store Review Guidelines update lets it remove apps that are already live, not just reject new submissions, if they go stale or stop attracting users. Here's what actually changed, which categories are already on the list, and what it means if you're an indie developer juggling more than one app.
Swift Testing Runs Your Suite in Parallel. That Static Var You Swap for DI Is a Race Condition.
Swift Testing parallelizes tests by default, in the same process. A huge number of Swift codebases — BrewLog's AppIntents suite included — still inject test dependencies by mutating a global static var. ST-0026 proposes a .taskLocal trait to fix it properly. Here's the real bug, the real code, and where the proposal stands.
Apple Just Open-Sourced the 'Skills API' Everyone Assumed Was a Claude Thing
Apple's new foundation-models-utilities package brings a Skills API, history compaction, and a chat-completions bridge to Swift's Foundation Models framework. Here's what's actually in the box, and how it maps onto BrewLog.
Swift Just Got a Real Timeout API. Here's What We've All Been Duct-Taping Instead.
SE-0526 withDeadline was accepted into Swift on July 30, 2026 — a real, composable, absolute-time-limit API for async operations. I found the exact gap it fills in a real app's networking layer, fixed it today's way with a TaskGroup race, and lined it up against what withDeadline will let me delete once it ships.
I Tried the Library That Puts Foundation Models, OpenAI, and MLX Behind One Swift API
SwiftAI is a new open-source Swift package that wraps Apple's on-device Foundation Models, OpenAI, and MLX behind one interface — reply(to:), @Generable structs, streaming, tool calls. I actually installed it, ran real on-device inference, and hit a documentation bug and a guardrail glitch within ten minutes. Here's what works, what doesn't, and whether it's worth adopting today.
Two-Thirds of AI iPhone Apps Hid the Key Under the Doormat
A Wake Forest study ran 444 AI-powered iOS apps through traffic analysis and found 282 of them leaking their own LLM API keys — OpenAI, Anthropic, cloud creds, the works. Stolen keys fuel 'LLMjacking' that can burn $46,000 a day on someone else's bill. Here's why it keeps happening and how to ship AI features with zero secrets in your bundle.
Agentjacking: The Call Is Coming From Inside Your Coding Agent
A new attack class called agentjacking hides malicious instructions inside Sentry error events. When you tell Claude Code or Cursor to 'fix the unresolved errors,' the agent reads the trap over MCP and runs the attacker's commands — with your privileges. 2,388 orgs were exposed, the success rate was 85%, and Sentry says it's 'technically not defensible.'
Your AI Agent Has Amnesia: Context Rot Is Why It Forgets Your Swift Codebase by Lunch
Context rot is the reason your coding agent starts brilliant and turns into a confidently-wrong intern two hours later. Chroma's study measured it across 18 models, it hits SwiftUI codebases hard, and the fix isn't a bigger context window — it's context engineering. Here's what actually works in Xcode 26.
Build Time Optimization for the Solo iOS Developer Running 5+ Apps
Day 30 of the 30-day iOS series. Real numbers, real DerivedData chaos, and the three things that actually move the needle on Xcode build times when you're maintaining multiple apps on one machine.
Custom Swift Macros: When They're Actually Worth the Build-Time Cost
Day 29 of the 30-day iOS series. The difference between @freestanding and @attached macros, why most macro ideas are over-engineering traps, and a real #URL macro — built TDD-first as a standalone Swift package — that catches BrewLog's force-unwrapped base URL at compile time instead of runtime.
UIKit Tricks SwiftUI Still Can't Do (Yet): Back to UIViewRepresentable
Day 28 of the 30-day iOS series. SwiftUI has no PDF viewer, no custom keyboard primitive, and no waterfall grid — five real gaps where you still reach for UIViewRepresentable, anchored by a real PDFKit-backed brew history export built TDD-first for BrewLog.
Combine in 2026: The Three Cases Where It's Still Better Than async/await
Day 27 of the 30-day iOS series. A real searchable brew history for BrewLog, built with Combine instead of async/await, and the three reasons it was the right call: debounce, independent multiple subscribers, and a four-way CombineLatest pipeline.
Live Activities and the Dynamic Island: A Decision Matrix, Not a Demo
Day 26 of the 30-day iOS series. A real ActivityKit countdown for BrewLog's pour-over timer, the one-function decision matrix that decides which brew methods even get one, and the exact reason it still won't show up on a Lock Screen.
WidgetKit and App Intents: Logging a Brew Without Opening the App
Day 25 of the 30-day iOS series. A real App Intent that logs a brew from Spotlight or a widget button, the @Dependency crash that nearly cost me an evening, and the honest line between what's tested and what's still a mechanical Xcode step.
SOLID Principles in Swift: One Bad Class, Five Real Fixes
Day 24 of the 30-day iOS series. Skip the acronym slide — here's the 70-line class I'd have shipped on day one of BrewLog, broken against all five SOLID principles, and the five already-tested files in this same repo that actually fix it.
Retry, Token Refresh, and Request Deduplication in Swift
Day 23 of the 30-day iOS series. The three production concerns every 'build your own networking layer' tutorial skips, built as composable actors on top of Day 22's client — plus a real concurrency bug I found writing the test, not the code.
A Custom Networking Layer in 100 Lines of Swift — No Alamofire
Day 22 of the 30-day iOS series. URLSession, async/await, a generic Endpoint, and one typed error enum — the entire networking layer is 85 real lines, tested with a URLProtocol stub, and wired into a real BrewLog feature with a real local server.
TDD for SwiftUI: A Red-Green-Refactor Workflow That Isn't Academic
Day 21 of the 30-day iOS series. I went looking for a BrewLog feature to drive test-first and found a real bug already shipped: the Streak stat has been hardcoded to zero since day one. Here's the actual red-green-refactor session that fixed it.
Swift Testing Framework: Why You Should Migrate from XCTest
Day 20 of the 30-day iOS series. @Test, #expect, parametrized tests, traits, and a side-by-side comparison on a real BrewLog test file. Plus: the one thing XCTest still does that Swift Testing doesn't.
Dependency Injection in Swift Without a Framework
Day 19 of the 30-day iOS series. Protocol-based DI, @Environment as a SwiftUI-native container, and the factory pattern — all without Resolver, Swinject, or any third-party glue. Includes a TDD example that shows why DI and testability are the same conversation.
Modular Architecture With SPM: When to Split (And When to Absolutely Not)
Day 18 of the 30-day iOS series, opening Week 4 on architecture. Modularization with Swift Package Manager has a real cost in build time, package graph complexity, and maintenance overhead. I show the threshold rule I use across five apps — below which you don't split, above which you must — with a real Package.swift example from BrewLog and a pure Swift Testing suite that proves the point.
StoreKit 2, Part 3: Server-Side Receipt Validation in 2026 (App Store Server API)
Day 17 of the 30-day iOS series, the finale of three on monetization. You can't trust the client — here's the minimal App Store Server API workflow for BrewLog: Server Notifications V2, JWSTransaction decoding, a Cloudflare Worker, and three pure Swift tests that prove the entitlement logic without ever calling Apple.
StoreKit 2, Part 2: Free Trials, Win-Back Offers, and Promo Codes That Actually Convert
Day 16 of the 30-day iOS series. I add a 7-day free trial, a win-back banner for lapsed subscribers, and offer-code redemption to BrewLog's paywall — concrete App Store Connect configuration plus the Swift code, all covered by Swift Testing.
A StoreKit 2 Paywall From Scratch: Subscriptions, a Transaction Listener, and a Restore Button That Works
Day 15 of the 30-day iOS series, first of a three-part run on monetization. I built BrewLog's real paywall with StoreKit 2 — two subscription products, a transaction listener, and a restore flow — with zero third-party SDKs. Every number the paywall shows comes from one pure, tested function.
SwiftData Two Years Later: What's Solid, What Still Bites, and the Migration Test You're Not Writing
Day 14 of the 30-day iOS series. SwiftData is about two years old now, and the honest verdict is mixed. I already wrote the long field report on where it broke in production — this post is the part that report didn't have room for: a VersionedSchema + SchemaMigrationPlan test that proves a schema change is safe BEFORE TestFlight finds out for you.
@Observable vs ObservableObject: What 1,000 Rows and a Redraw Counter Actually Showed Me
Day 13 of the 30-day iOS series. I built a redraw counter into BrewLog, put 1,000 rows in two identical lists side by side — one backed by @Observable, one by ObservableObject — and toggled a single favorite ten times. The row counts tied 10-10. The list counts didn't. Here's the real number, and exactly where it comes from.
@State, @Bindable, @Environment: The Complete Map for @Observable (and the Question You're Actually Asking)
Day 12 of the 30-day iOS series. With @Observable, SwiftUI lets you slap @State, @Bindable, @Environment, or a plain let on the same class — and compiles all of them. Here's the question that actually decides which one is correct, one map that resolves 95% of the confusion, and three real BrewLog bugs (one silent, one a compile error, one a runtime crash) that come from picking wrong.
ObservableObject → @Observable: The Migration Guide That Skips the Marketing (and the Autoclosure Gotcha Apple Forgot to Mention)
Day 11 of the 30-day iOS series. Apple's migration guide makes ObservableObject → @Observable look like a find-and-replace. It mostly is — except for one quiet behavioral change: @StateObject only ran your initializer once, and @State runs it on every render. Here's the multiple-init bug that causes, why it's worst in exactly the init you were proud of, and how to fix it with a test that turns 'no side effects in init' into a hard, green invariant.
The Keynote Made You Cry. The State of the Union Gave You Homework. Five Things That Actually Change Your iOS Workflow.
WWDC 2026 State of the Union broke open the developer toolbox: free Private Cloud Compute for indie devs, Foundation Models going open source, Xcode 27's Device Hub killing Simulator, agentic coding with Claude and Gemini inside your IDE, and SwiftUI finally caching images like it should have from day one.
ThinkBud + Foundation Models: What I Shipped On-Device, and the Wall That Sent Me Back to the Server
Day 10 of the 30-day iOS series, the build-in-public finale of AI week. I took the on-device Foundation Models stack from Days 8 and 9 and bolted it into ThinkBud, an app I actually ship. Here's the honest field report: the bounded tasks the on-device model nailed for free and offline, the context-window wall a 100K-character textbook import smashed into, and the exact line of code where I gave up and routed to a server. Plus the one decision that's pure Swift — so it gets a real test.
Tim Cook Wiped a Tear, Siri Got a Google Brain, and Apple Shipped a Transparency Slider. WWDC 2026, Honestly.
The WWDC 2026 keynote just happened. Tim Cook's emotional farewell, Siri rebuilt on Gemini, Core AI replacing Core ML, Xcode 27 going full MCP, and Liquid Glass finally getting a slider. Here's what actually matters for your iOS codebase — no press release fluff.
CS Enrollment Dropped 11%. The Industry That Needs Developers Told Students Not to Bother.
Computer science enrollment fell 11.2% in 2026 — the steepest drop of any major. CS dropped from the 4th to 6th most popular degree. 64% of students cite AI as the reason. Meanwhile, the same companies cutting junior roles are complaining about a talent shortage. The Karate Kid problem is real: skip the fundamentals, and nobody can fight when it matters.
@Generable: Make Apple's On-Device Model Hand You a Swift Struct, Not a String to Parse
Day 9 of the 30-day iOS series, part 2 of AI week. Yesterday Foundation Models gave us a String. Today we make it give us a typed Swift value — BrewSummary(flavor:, advice:, rating:) instead of a paragraph you regex your way through. @Generable, @Guide constraints, session.respond(to:generating:), and the sleeper-within-the-sleeper: tool calling, where the on-device model calls your own Swift code mid-answer. With the TDD seam, because typed output changes what you test.
AI Made Developers 19% Slower. They Swore It Made Them 20% Faster.
A peer-reviewed study found that experienced developers were measurably slower with AI coding tools — but genuinely believed they were faster. Then Uber blew its entire 2026 AI budget in four months. Then Amazon had to kill its own leaderboard because employees were gaming it. The productivity paradox is real, it's expensive, and it might explain why your sprint velocity feels off.
Foundation Models: Your First On-Device AI Feature With No Backend, No API Key, No Bill
Day 8 of the 30-day iOS series, and the start of AI week. The Foundation Models framework runs a real language model entirely on the phone — free, private, offline. We build the smallest thing that works: summarize a block of text in three lines, handle the availability cases that bite in production, wire it into a real app, and put a TDD seam around the part that isn't the model. Code-along, with tests.
UIDesignRequiresCompatibility: When (and Why) Opting Out of Liquid Glass Is the Pro Move
Apple hands you one Info.plist key that freezes the old design for a full year. It's not a cop-out — for banking, enterprise, and apps caught mid-redesign, opting out of Liquid Glass is the responsible call. The exact flag, a real before/after from my own app, the deadline, and a decision matrix you can actually defend in a standup. Plus the per-screen rollout gate you should be testing instead.
Icon Composer and the New App-Icon Era: One Document Instead of Three Exported PNGs
iOS 26 wants your app icon in light, dark, clear, and tinted. The old way was three flat 1024px PNGs that quietly drifted apart. Icon Composer turns it into one layered .icon document the system relights for you. The real workflow from a single SVG to a full set — plus the one decision around icons you can actually unit-test.
Custom Liquid Glass Components: When to Leave the Defaults (and the Three Mistakes That Kill Your Frame Rate)
glassEffect(.regular, in:) with a custom shape, two glass blobs that morph into each other with glassEffectID, and the three things that turn buttery Liquid Glass into a stutter machine. Built on a real iPhone 17 Pro simulator, with the TDD seam that keeps the decision testable even though the render isn't.
Tim Cook's Curtain Call: His Last WWDC Keynote and What Changes for Every iOS Developer
Tim Cook delivers his final WWDC keynote on June 8 before handing the CEO role to hardware chief John Ternus on September 1. After 15 years, a $350B-to-$4T run, and a developer ecosystem of 2.3 billion devices, here's what the transition actually means for people who write Swift for a living.
Liquid Glass for an App You Already Shipped: What You Get From a Recompile vs. Five Lines of Tuning
I rebuilt a real SwiftUI app against the iOS 26 SDK and took two screenshots of the exact same screen — one with zero code changes, one with five lines of glassEffect. Here's the honest split between what the recompile hands you for free and what's worth your custom-tuning time, plus the TDD seam that makes a visual feature testable.
Apple Said 'All Systems Glow.' Developers Said 'Not So Fast.'
Apple dropped its WWDC 2026 tagline yesterday and the developer forums immediately caught fire. Half the community is excited for iOS 27's AI overhaul. The other half is already mourning the operating system they used to love. With six days until the keynote, here's what the divide tells us about where Apple is headed.
Your App Just Got an Eviction Notice: Liquid Glass Is Mandatory in iOS 27
Apple confirmed Liquid Glass is non-negotiable in Xcode 27. Your custom tab bars, navigation views, and carefully crafted layouts are about to meet a wrecking ball called UIDropShadowView. Here's exactly what breaks, what the timeline looks like, and how to survive the migration before WWDC drops on June 8.
Migrating a Real App to Swift 6.2 Strict Concurrency: 86 Errors, One Afternoon, One Race Condition I Didn't Know I Had
I migrated Invoize from Swift 6.0 strict mode to Swift 6.2 approachable concurrency on a Sunday afternoon. Every warning, every fix, the one real race condition the compiler finally surfaced — and the TDD seams I leaned on so the migration wasn't just compiler-driven guessing.
Tech Just Closed the Youth Academy: The Junior Developer Crisis Nobody's Planning For
Junior developer hiring dropped 73% in one year. Big Tech went from 32% junior hires to 7%. Companies are choosing $20/month AI tools over $80K entry-level salaries. But here's what every football fan already knows: if you shut down the academy, you won't have any stars in five years.
@concurrent vs nonisolated vs @MainActor: The Swift 6.2 Decision Tree That Fits on a Napkin
Four real scenarios — UI update, network call, image decode, file IO — and exactly which Swift 6.2 isolation keyword each one needs. A TDD walk-through with Swift Testing, no whiteboard ceremony required.
Apple Is Turning Every App Into an AI Tool — MCP Support Means Siri Was Just the Warm-Up
Apple is building native Model Context Protocol support on top of App Intents. That means Claude, ChatGPT, Gemini, and every other AI agent will be able to control your app — not just Siri. Nine days before WWDC 2026, here's what this means for iOS developers and why your App Intents just became the most important code you've ever written.
MainActor by Default: Why Apple Just Reversed Swift's Concurrency Story
Xcode 26 flips the default — your code now runs on the main actor unless you say otherwise. Here's why Apple changed direction, what it actually means for your existing project, and a TDD walk-through showing the migration in real Swift.
Google's AI Is About to Run on Every iPhone. Apple Thinks That's a Feature, Not a Bug.
Apple is training distilled versions of Google's Gemini to run directly on iPhones. For iOS developers, this means your Foundation Models code might soon be powered by Google under the hood — and WWDC 2026 will make it official. Here's what changed, why it matters, and what to build before June 8.
The Meter Is Running: GitHub Copilot Goes Pay-Per-Token, and Every Developer Just Became a Day Trader
GitHub Copilot switches to usage-based billing on June 1. Your $10/month plan now comes with a token budget, and heavy users are staring at potential 5x overages. Here's what actually changed, where developers are fleeing, and how to pick the right AI coding tool without going broke.
Apple Registered genai.apple.com. Twelve Days Before WWDC, the Biggest Clue Just Dropped.
Apple quietly registered a GenAI subdomain last week. It's not live yet, but the timing — twelve days before WWDC 2026 — tells us everything about where the iOS developer platform is headed. Core AI, Siri Extensions, Foundation Models, and a public-facing AI hub. Here's what it means for your next project.
Your Bug Fix Is Behind 235,800 Vibe-Coded Apps. Welcome to App Review in 2026.
App Store review times ballooned from under 24 hours to multi-week waits after vibe coding drove an 84% surge in submissions. Indie developers with critical bug fixes are stuck behind a flood of AI-generated apps. Here's the data, the developer stories, and what you can actually do about it.
I Wrote Swift in Cursor for a Week. Xcode, We Need to Talk.
Swift officially hit the Open VSX Registry — meaning Cursor, Kiro, and every AI IDE now support Swift with full LSP, debugging, and test explorer. I spent a week building iOS code outside Xcode. Here's what worked, what didn't, and why Apple publishing a Cursor setup guide is the most understated power move of 2026.
Liquid Glass Turns One. We're Still Squinting.
Apple's Liquid Glass design language is celebrating its first birthday — and the party is divided. With WWDC 2026 two weeks away and iOS 27 doubling down, here's where things actually stand for developers: the wins, the accessibility mess, the adoption gap, and why your next SwiftUI update might need reading glasses.
Apple Is Building an AI App Store Inside Siri. Most Developers Haven't Noticed Yet.
iOS 27 will turn Siri into a chatbot with third-party Extensions — a dedicated App Store section for AI integrations. This is the biggest new distribution channel since widgets. Here's what indie iOS developers should be building right now.
Swift Has 217 Keywords Now. Nobody Agrees on What It's For.
Swift started as a simple, elegant language that composed beautifully. Twelve years later, it has 217 keywords, a governance problem, and an identity crisis. With WWDC 2026 weeks away, the community is asking: is Apple killing its own programming language?
Apple's WWDC 2026 Invite Says 'Coming Bright Up' — We Decoded Every Pixel
The WWDC 2026 media invites dropped yesterday with a glowing Swift logo and the tagline 'Coming Bright Up.' Here's what Apple is really telling us about Siri 2.0, the Gemini partnership, and what iOS developers should prepare for in the next 20 days.
Apple Just Invented the Gym Membership for Apps. Here's Why That's Brilliant.
iOS 26.5 shipped a new subscription model — monthly payments with a 12-month commitment. It's the gym membership of the App Store. And for indie developers bleeding from monthly churn, it might be exactly what the doctor ordered.
Your Xcode Has a Built-In MCP Server. Most iOS Developers Haven't Noticed Yet.
MCP is the protocol that lets AI tools talk to everything — your code, your simulator, your build system. Xcode 26.3 shipped one quietly. There's an official Swift SDK. And WWDC 2026 might make it the backbone of CoreAI. Here's what iOS developers need to know before everyone else figures it out.
Visual Intelligence Is the Sleeper Hit of WWDC 2026. Most Developers Don't See It Coming.
Apple is opening Visual Intelligence to third-party developers at WWDC 2026 — nutrition scanning, contact capture, Wallet passes, and a full camera AI pipeline. While everyone argues about Siri, this is the API that will actually change how your app works. Here's what we know and how to prepare.
Xcode 26.5 Just Made Its AI Agent Less Annoying. Is That Enough?
Xcode 26.5 shipped two small features — message queuing and clarifying questions — that fix the most frustrating parts of agentic coding. Here's what actually changed, why it matters more than it sounds, and whether Apple's AI coding agent is finally ready for your daily workflow.
Apple Wants You to Move Into Siri's New House. Read the Lease First.
iOS 27 turns Siri into a full chat app with conversation history, document uploads, and deep app integration. Apple is courting developers to build for it — but won't promise it won't charge commission later. Here's why some developers are hesitating, and what you should actually do.
WWDC 2026 Is 26 Days Away. This Is Your iOS Developer Pre-Flight Checklist.
WWDC 2026 lands June 8. SiriKit deprecation, Core AI replacing Core ML, Liquid Glass refinements, foldable iPhone APIs, and strict concurrency in Swift 7. Here's the practical pre-flight checklist to run through your codebase right now — before the keynote makes it urgent.
iOS Refund Abuse Has a TikTok Tutorial Now. Your Client-Side Receipt Check Is the Cashier Who Looks Away.
Subscription refund fraud quietly climbed past 11% on iOS in 2026, fueled by TikTok scripts and a 90-day Apple refund window most indies never reckoned with. Client-side receipt verification can't see any of it — and the gap between StoreKit's ‘.verified' and what your business is actually owed is now too big to ignore.
Vibe Coding Has a Free-Rider Problem. Open Source Maintainers Are Paying the Bill.
AI coding tools consume open source libraries at scale but skip the human behaviors that keep them alive — bug reports, documentation visits, sponsorships. With 60% of maintainers unpaid and burnout at 44%, the ecosystem that powers your app might not survive the vibe coding era.
The App Store Just Had Its Biggest Quarter in History. Here's Why That's a Problem.
App Store submissions are up 80% on iOS. AI coding tools turned everyone into a developer overnight. But when 200,000 new apps hit the store every week, the question isn't whether you can build an app anymore — it's whether anyone will find it.
Apple Just Turned AI Into a Settings Toggle. Your App Has No Idea Which Brain Is Driving.
iOS 27 Extensions let users swap Siri's brain between Gemini, Claude, and ChatGPT. It's the default browser moment, but for intelligence. Here's what iOS developers need to prepare before WWDC on June 8.
App Intents Are the New SEO — and Most iOS Developers Are Still Invisible
Siri is becoming the front door to every iPhone. App Intents are no longer a nice-to-have — they're the difference between discoverable and dead. Here's a practical guide to making your app visible before WWDC 2026 changes the rules.
An AI Agent Nuked a Database in 9 Seconds. Aviation Safety Has the Fix.
A Cursor agent powered by Claude Opus deleted a startup's entire production database and backups in under 10 seconds. The aviation industry solved this class of problem decades ago. Here's the Swiss cheese model applied to AI coding agents — and the pre-flight checklist every developer needs.
I've Been Pair Programming With Xcode's AI Agent for 3 Months. We Need to Talk.
Xcode 26.3 shipped agentic coding with Claude and Codex in February. Three months later, here's what it's genuinely great at, where it falls apart, and why it made me rethink how I write SwiftUI code — for better and worse.
iOS Interviews Are Broken in 2026 — And Everyone Knows It
Companies test you on raw Swift memorization while their production code is 40% AI-generated. The iOS interview process in 2026 is a theater performance nobody believes in anymore. Here's what's actually wrong and what should replace it.
Swift 6.3 on Android, Three Weeks In: What Actually Broke and What Surprised Me
When Apple shipped Swift 6.3 with first-class Android support last month, I bet a Saturday on porting a piece of ThinkBud's sync engine to Android. Three weeks of usage later — here's what stuck, what didn't, and the one bug that taught me more than a year of Swift Concurrency reading.
What iOS Dev Land Is Missing in 2026 — and a Few Things I Built to Fill the Gaps
There are a handful of small, specific frictions every iOS developer hits this year that should not still exist in 2026 — Privacy Manifests, Universal Links validation, iOS 26 icon variants, App Store screenshots. Walking through what's actually missing, why it persists, and four free tools I made for myself that you might find useful too.
Swift 6.2 Finally Made Concurrency Approachable — Someone Already Built a Parody Site
Swift 6.2 ships @MainActor by default, the new @concurrent attribute, and a complete rethink of strict concurrency. We break down what changed, show real migration code, and explain why the community is both celebrating and arguing.
Claude Code vs Cursor: I Used Both for a Month. One Tried to Charge $1,400.
Cursor is the sous chef who hands you the knife before you ask. Claude Code is the contractor who remodels your kitchen overnight. We tested both on real iOS projects and here's when each one wins — plus how to avoid that terrifying billing surprise.
Swift 6.3 Now Officially Runs on Android. I Tried It. Here's What Actually Works.
Apple shipped an official Swift SDK for Android with Swift 6.3. Not a hack, not a community port — the real thing. We tested it on a real project and here's every win, every friction point, and the honest verdict on whether iOS developers should care.
GitHub Copilot Just Installed a Parking Meter on Your Code Editor
GitHub Copilot is switching to usage-based billing on June 1. Same price, fewer guarantees, and your unused credits vanish every month. The flat-rate AI coding era is officially over — here's what it means for developers and what your options actually are.
We Updated Our App Icon for iOS 26. Apple Now Wants Three of Them. So We Built a Tool.
iOS 26 Liquid Glass quietly tripled the work to ship an app icon — default, tinted, and dark variants for every iPhone app. Existing icon tools haven't caught up. We hit the wall updating ThinkBud last week, so we built a free generator. Here's what changed in iOS 26, why every iOS dev is about to learn this the hard way, and the tool we shipped to handle it.
Apple's iOS 26 SDK Deadline Hits Tomorrow. Half the App Store Isn't Ready.
April 28, 2026 — every app submitted to the App Store must be built with Xcode 26 and the iOS 26 SDK. If you haven't updated yet, your next submission gets rejected. Here's what's breaking, what you need to fix, and why this deadline is different.
I Migrated Two Apps to SwiftData. Eighteen Months Later, I'm Migrating Half of It Back.
SwiftData turns three at WWDC 2026. After running it in production across two shipping iOS apps for a year and a half, here's an honest field report — what works, what quietly broke, and the three places we went back to Core Data and don't regret it.
We Gave Claude Mythos Full Access to Our Codebase. It Shipped Three Features Before Lunch.
After a week of security testing, we let Anthropic's most restricted AI model loose on real development work. It refactored our state management, found a memory leak we'd chased for months, and rewrote our networking layer across four apps. Week two was a different beast.
Apple Is Shipping Foldable iPhone APIs Before the Foldable iPhone. That's Either Genius or Chaos.
WWDC 2026 drops June 8. Apple is giving developers fold-state detection, Core AI replacing Core ML, macOS touch APIs, and a Siri that lives in the Dynamic Island. Here's what you need to know and what we're already building.
Apple Paid Google a Billion Dollars to Fix Siri. It Might Actually Work This Time.
Apple signed a $1B/year deal with Google to power Siri with Gemini. The WWDC 2026 graphic teases a full chatbot redesign in the Dynamic Island. Third-party AI extensions are coming. Here's what developers actually need to know.
We Got Our Hands on Claude Mythos Preview. Here's What Actually Happened.
We spent a week testing Anthropic's most restricted AI model through Amazon Bedrock's gated preview. It rewrote our security scanning pipeline, found a bug we'd missed for two years, and made us rethink what AI-assisted development actually means.
Apple Put a 3-Billion Parameter Brain Inside Every iPhone. Most Developers Haven't Even Noticed.
Apple's Foundation Models framework lets you run AI on-device with 3 lines of Swift. No API keys. No cloud bills. No privacy headaches. Here's why iOS developers should stop ignoring the smartest thing Apple shipped in years.
The iPhone Fold Ships in September. Your App Layout Just Had a Panic Attack.
Apple's foldable iPhone has entered trial production. A 7.76-inch inner display, book-style fold, and no Face ID. SwiftUI developers have a head start. UIKit holdouts should start stretching.
Apple Stopped Pretending It Could Build AI Alone. That's the Best WWDC News in Years.
WWDC 2026 is two months away. Apple is opening Siri to Claude, Gemini, and Grok. Xcode already has agentic coding. iOS 27 is a stability year. Here's what iOS developers actually need to care about.
Apple Gave iOS a Makeover Nobody Asked For. Now Everyone Has to Live With It.
Liquid Glass is permanent, expanding, and mandatory in iOS 27. Apple's VP of design left for Meta. Developers lost customization options. Users can't read their screens. And Apple just told everyone to deal with it.
