XcodesApp Release Notes

Highlights

• Refactored XcodesApp to use the shared, concurrency-enabled XcodesKit package.

• Added an optional grouped Xcode list view that collapses versions by major/minor release.
• Added federated Apple ID authentication support.
• Updated install, runtime, update, helper, selection, and uninstall flows to use Swift concurrency tasks instead of Combine publishers.
• Removed duplicated in-app Apple API/XcodesKit model code now provided by shared packages.
• Updated dependencies, including XcodesKit 1.0.0 and XcodesLoginKit.
• Cleaned up obsolete dependencies such as ErrorHandling and CombineExpectations.
• Improved test coverage around app state, update behavior, grouped-list defaults, and shared XcodesKit mocks.

Xcode And Runtime Filtering

• Xcode list filtering now uses shared XcodesKit filter logic.
• Runtime and Xcode architecture filters are handled consistently through architecture variants.
• The architecture filter defaults to the best match for the current machine.
