Xcode 27

Microsoft has published guidance on migrating .NET MAUI apps to the UIKit scene lifecycle ahead of Xcode 27. The walkthrough on the .NET blog explains what iOS and macOS developers need to change to keep their apps building and running with the new toolchain, and developers are sharing the guide across app development communities.

Apple is preparing the App Store for its upcoming foldable iPhone, reportedly called iPhone Duo. From April 2027, developers submitting new apps via Xcode 27.1 will need to provide screenshots showing how their software runs on the foldable device. The move signals Apple is finalising plans for its first foldable iPhone, with support built into iOS 27 and iPadOS tooling.

Apple's latest developer tooling update lets teams adopt Xcode 27 and its Liquid Glass design language without disrupting existing redesign timelines. The weekly roundup also covers a JPA-inspired ORM, OpenTelemetry integration, WebSocket support, push callbacks, and native desktop themes, drawing attention from Java, Android, and iOS developers discussing how the changes fit into current app roadmaps.

Apple's Xcode 27.1, released ahead of October 23, adds support for a foldable device referred to as the iPhone Duo, including App Store screenshot templates. From April 2027, developers will be required to include screenshots for the foldable form factor when submitting apps. It remains unclear whether updates to existing apps will also need to comply.
