Apple recently announced that, starting April 2026, all watchOS apps submitted to the App Store via App Store Connect must include a 64-bit slice. This move, revealed in July 2025, continues Apple’s push for platform stability, performance, and future-proofing. The requirement aligns watchOS guidelines with iOS and iPadOS, ensuring newer hardware can take full advantage of app performance improvements.
Developers should ensure their apps are compiled with a minimum of Xcode 16 and updated for the latest watchOS SDK, as older 32-bit submissions will be rejected moving forward.
These stories underscore the ongoing innovation and security focus in the app ecosystem—Google polishes the Android user experience while Apple ramps up technical standards for the next generation of apps.
