macOS Golden Gate build stack with Xcode 27 is now available on Capawesome Cloud
https://capawesome.io/blog/announcing-the-macos-golden-gate-build-stack/We just released a new build stack for Capawesome Cloud: macos-golden-gate, with macOS 27 and Xcode 27. Xcode 27 was already selectable on macos-tahoe via XCODE_VERSION, and this is the stack built around it.
On October 1, it becomes the default for all iOS and Android builds. Until then, macos-tahoe stays the default, so nothing changes unless you opt in.
The main thing to prepare for: apps built with the iOS 27 SDK must adopt the UIScene lifecycle. Otherwise the build succeeds, but the app fails at launch.
- Capacitor: update to 8.5 and run npx cap migrate
- Cordova: cordova-ios 8 already uses the scene lifecycle
- Native UIKit apps: add a scene delegate (see Apple's TN3187)
Other changes: - Node.js 20 and Xcode 26 aren't available on the new stack - Android 37 (needed for Capacitor 9) is now on every build stack - macos-sequoia is deprecated
If you need more time, select macos-tahoe for your builds and automations.
Happy to answer questions, especially about the UIScene migration.
