Deprecation of Xcode 15.x

[helinanever]

Starting November 10, 2025, we will remove the following build machines from our platform:

• Mac machines running macOS 13.5.2 and Xcode 15.0
• Mac machines running macOS 14.2 and Xcode 15.1
• Mac machines running macOS 14.2.1 and Xcode 15.2
• Mac machines running macOS 14.3.1 and Xcode 15.3
• Mac machines running macOS 14.4.1 and Xcode 15.4

We are making these changes to ensure that builds on Codemagic run with the highest level of reliability and security. In addition, since April 24, 2025, Apple requires all apps uploaded to App Store Connect to be built using Xcode 16 or later.

Before the build machines are removed completely, we will be conducting several brownouts during which the builds using the machines listed above will fail. Please migrate your workflows ahead of time to avoid any disruptions in the future.

How to migrate

You are affected by this change if your build workflow is set to use Xcode version 15.x.

Please review and update your build configurations to use Xcode 16 or higher. Xcode version can be configured in the environment section of codemagic.yaml or in the Build section of Flutter Workflow Editor.

You may need to make additional changes in your workflow if your builds use old versions of pre-installed software. Compare the machine specifications in our documentation.
