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 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.

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.

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.

@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.

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.

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.

@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.

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.

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.

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.
