Apple is requiring all apps built for its platforms to be built with Xcode 13, starting April 25, 2022, which includes SDKs for iOS 15, iPadOS 15, and watchOS 8. This means that after this date, only apps built on or above Xcode 13.x can be submitted to the App Store. Apple will still support older operating systems, but no new apps can be submitted without using Xcode 13. By supporting Xcode 13, Bitrise provides fast and easy automated builds, testing, and app deployment for mobile apps, ensuring developers have access to the latest mobile stacks and tooling.
