What is it I'm supposed to say? "Some personal news?" 😂 swiftpackageindex.com/blog/swift-p... So proud of what Sven and I built so far with SPI, and I'm happy to say I'll be joining Apple to continue working on everything related to Swift packages! 🥂

Worth repeating: Anthropic's Claude selected the girl's school for bombing, despite plenty of public evidence it was not a military target.

Starting a 🧵 called "AI hater's reading list" ⬇️, for us haters who like to do our homework. Each of these are books I've read and recommend you do as well. Pretty sure this can turn any AI booster into a hater, these books are exceptionally well-researched. Enjoy! 💪 (And reply with more tips!)

Have you ever encountered to store weak references in an array in other words using arrays with weak references? I know that’s not a case for every array usage in Swift but that’s not an excuse not to know how to achieve it. emredegirmenci.substack.com/p/swift-nspo... #swiftlang #iosdev

Memory-safe. 13% faster on average. ⚡️ The TrueType hinting interpreter in macOS and iOS has been rewritten in Swift, replacing the original C implementation. Pixel-perfect accuracy was validated across 27 million glyphs. And the results: www.swift.org/blog/migrati...

I found my favorite #wwdc26 session! Must watch for king SwiftUI devs :D www.youtube.com/watch?v=HTDU...

Did you catch the WWDC Swift Group Lab session? It was great! But, there wasn't time for all the questions. So I copied them down and took a shot at answering some. www.massicotte.org/blog/wwdc26-...

SwiftUI Perf Tip: In lazy containers (List, LazyVStack), each ForEach element should return a *constant* number of views. An AnyView or if inside the closure (0 or 1 views) hits a slow path. Fix: filter your data upfront. Debug arg: -LogForEachSlowPath YES 🔗 developer.apple.com/documentati...

I'm really scared when I first saw Xcode 27's default theme (especially the purple color🤮) hopefully they put an option to select Xcode 26 easily 😮‍💨 #xcode27 #wwdc26

When you draw a stroke in Goodnotes on the web, you get the exact same curves and ink flow as on iPad, because it’s literally the same Swift code running on both. ✍️ Goodnotes engineer Yuta Saito shares how they built it with Swift and WebAssembly: www.swift.org/blog/bringin...

Mentee interest surveys date changed and opened now!

Recently, I was asked interesting question. If the purpose of an actor is to protect mutable state, is a stateless actor pointless? It is definitely something to look at closely, but there are some uses that can make sense. www.massicotte.org/stateless-ac...

It's so weird that SwiftUI still has no map annotation clustering capability. Of course, there’s a highly efficient third-party solution called ClusterMap. I explained how I resolved that issue by utilizing it. emredegirmenci.substack.com/p/swiftui-ma... #swiftlang #iosdev #mapkit

In the real world, you'll face APIs you can't change. And probably hear; 😱We don't know how it works, and we're afraid to touch it. 😏You should implement MY API instead. That's exactly why the Adapter Pattern exists 🔌 Don't fight the code. #swiftlang #iosdev open.substack.com/pub/emredegi...

Been almost six months since I last did one of these. But I've always wanted to get into how Swift Concurrency influences designing protocols. Big topic, definitely not exhaustive! Also could not help myself - there's quite a bit on default isolation too. www.massicotte.org/step-by-step...
