Swift shipped twice this cycle: 6.3 in the spring and 6.4 alongside Xcode 27 at WWDC. Module selectors, async defer, and task cancellation shields are the three changes you'll actually use.
iOS 27 lets you drag to reorder in any container, add swipe actions outside of List, and cache AsyncImage responses. A tour of the headline SwiftUI changes from WWDC 2026, with code.
Before WWDC 2026 I wrote down predictions and never hit publish. Four months later, with iOS 27 out and iPhone Duo days away, it's time to grade them against what Apple actually shipped.
App Store Connect now takes iPhone Duo screenshots, with separate sizes for the inner and outer displays. Here are the exact dimensions, how to capture them in the simulator, and when Apple starts requiring them.
When two windows share iPhone Duo's inner display, neither one is told which side it's on. I built a proof of concept in Xcode 27.1 and found the fold's ReservedRegion answers it, once you know its frame is clipped to your window.
iOS 27.2 changes App Tracking Transparency in the European Union: a full-page prompt with Markdown text, an optional Additional Information button, and a yearly re-prompt. Here's who sees what and how to adopt the new API.
