Summary

Updates the .NET bindings for Xcode 27.0 Beta 4 across frameworks that had already been updated through Beta 3. This resolves the new XTRO discrepancies, tracks APIs Apple changed or removed between betas, and adds the native SIMD messaging support required by the new ARKit APIs.

Updated frameworks

  • AppKit
  • ARKit
  • AudioToolbox
  • AutomaticAssessmentConfiguration
  • AVFoundation
  • AVKit
  • BrowserEngineKit
  • CarPlay
  • CoreLocation
  • UIKit
  • UserNotifications

Also reviewed with no additional source changes required:

  • BackgroundAssets — the Beta 4 header changes are Swift-only.
  • WebKit — the required Beta 4 changes were already included in the Beta 4 bump.

Notable changes

  • Adds the AppKit/UIKit Writing Tools grammar APIs and UIKit reduced-resource traits.
  • Adds ARKit view-rotation APIs and their native SIMD trampolines.
  • Adds new AudioToolbox, AutomaticAssessmentConfiguration, AVFoundation, CarPlay, and CoreLocation APIs.
  • Applies new deprecations and platform availability changes in ARKit, BrowserEngineKit, and UIKit.
  • Removes AVKit and UserNotifications APIs that Apple introduced in Beta 3 and removed in Beta 4.
  • Preserves the existing Mac Catalyst exclusions for ARKit and CarPlay.

Validation

  • Full make world build passed.
  • Clean XTRO generation/classification passed with Sanity check passed.
  • Cecil tests: 112 passed, 4 skipped, 0 failed.
  • Introspection:
    • iOS 27.0: 44 passed, 0 failed.
    • tvOS 27.0: 43 passed, 0 failed.
    • macOS: 32 passed, 2 expected OS-version skips, 0 failed.
    • Mac Catalyst: all non-constructor fixtures passed; the full constructor fixture hit the documented headless TCC crash in CLLocationButton.
  • App-size tests exited successfully with 16 expected skips because they are disabled for beta Xcode releases.

Pull request overview

Updates the .NET bindings and API annotation baselines to align with Xcode 27.0 Beta 4 for frameworks that were previously updated through Beta 3, resolving various XTRO-reported gaps and adjusting the documentation known-failures list accordingly.

Changes:

  • Add/adjust bindings for new Xcode 27 APIs across UIKit/AppKit, ARKit, CarPlay, CoreLocation, AVFoundation, BrowserEngineKit, AutomaticAssessmentConfiguration, and AudioUnit.
  • Regenerate XTRO api-annotations: remove resolved *.todo files and move MacCatalyst-specific non-binding decisions into *.ignore where applicable.
  • Update Documentation.KnownFailures.txt to reflect new/removed public surface items.
