Исследование производительности механизмов синхронизации в Swift
За время работы iOS-разработчиком я не раз встречал те или иные рекомендации по выбору быстрого механизма синхронизации. Если нужна высокая производительность, то используйте os_unfair_lock . Если чтений гораздо больше, чем записей, то присмотритесь к read-write lock или concurrent queue с barrier-записью. А когда речь заходит о Swift Concurrency, нередко можно услышать, что actors работают медленно и проигрывают обычным блокировкам. Мне захотелось проверить, насколько эти рекомендации подтверждаются на практике. Поэтому я решил сравнить механизмы синхронизации в задачах, похожих на те, которые встречаются в реальных приложениях. И заодно выяснить, есть ли механизм, который можно выбирать по умолчанию для большинства таких задач.

Started adding some specialized alerts for busy accounts on the web. Tomorrow night, let’s do the same during sync issues. See you then!

363,562 pages became 391,056, and no page was lost.
I diffed Cupertino's Apple documentation database, June against November. 126,695 pages were re-read from Apple's structured data, 27,494 are new, and the docs now describe a foldable iPhone, iPhone Duo, with new SwiftUI and UIKit APIs for hinges and reserved regions.
It also found two defects. I list them in the post.

AppTraction launches today! This could be a game changer for anyone with apps on the App Store.
What it is: a privacy-focused Mac app that helps you understand and improve how your apps do on the App Store.
About me: I spent 10 years as an engineer at Apple working on macOS and iOS, and I’ve been indie for the last 8, shipping 20+ apps for myself and clients. AppTraction is the tool I wish I’d had when I started building my own apps.

Finished auditing the app for account-busy statuses. Tomorrow night, let’s audit the web frontend for the same thing. See you then!

Found what looks like a StoreKit regression in iOS 27 and filed it as FB25514964 🙏
If a user's subscription gets refunded and they later want to subscribe again, iOS 27 hands back the old refunded transaction instead of creating a new one. The purchase reports success, but the user never gets their subscription back. On iOS 26 the same steps work as expected.
I tested both versions side by side with a minimal sample project and (1/2)
