Summary

  • Bind the Core Image APIs introduced in Xcode 27 Beta 3 across iOS, tvOS, macOS, and Mac Catalyst.
  • Add CIImage decoding options, image-processor scratch resources, tiled processing, RAW camera-model and despeckle controls, and render estimation metrics.
  • Preserve compatibility for new required protocol members with XAMCORE_5_0 guards and matching xtro exceptions.
  • Remove all resolved CoreImage todo files and allow the new Despeckle API terminology in introspection tests.

The despeckle members are explicitly gated to 27.0 because they are absent from the Xcode 26.4 and 26.5 SDKs, even though the Xcode 27 Beta 3 headers omit member-level availability annotations.

Validation

  • make world before and after the binding changes
  • Clean xtro classification: sanity passed
  • Clean cecil suite: 112 passed, 4 skipped, 0 failed
  • iOS 27 introspection: 44/44 passed
  • tvOS 27 introspection: 43/43 passed
  • macOS introspection: 32/32 passed, 2 host-version-gated
  • Mac Catalyst introspection: 39/39 passed, 4 expected ignores
  • App-size suite: 0 failed; all 16 cases intentionally skipped on beta Xcode

[CoreImage] Update bindings up to Xcode 27.0 Beta 3
2f42b6a 
Bind the Core Image APIs introduced in Xcode 27 Beta 3 across iOS, tvOS, macOS, and Mac Catalyst.

- Expose new CIImage decoding options and image-processor scratch resources.
- Add RAW camera-model and despeckle APIs, tiled processing, and render estimates.
- Preserve compatibility for new required protocol members with XAMCORE_5_0 guards and xtro exceptions.
- Remove the resolved platform todo baselines and recognize the new public API terminology in introspection tests.

Pull request overview

This PR updates the CoreImage binding surface to match new APIs in Xcode 27.0 Beta 3, and keeps the repository’s validation tooling (xtro + introspection typo checks) aligned with the new terms/protocol requirements.

Changes:

  • Added new CoreImage bindings in src/coreimage.cs (RAW camera-model querying + despeckle controls, CIImage decode options/keys, processor scratch resources, tiled processing, render estimation metrics).
  • Updated xtro expectations by removing resolved CoreImage .todo files and adding new protocol-required-member exceptions to common-CoreImage.ignore.
  • Allowed the new “Despeckle” term in ApiTypoTest so introspection spelling checks accept the new API terminology.

[CoreImage] Make new protocol members required
8be241e 
Make the Xcode 27 CIImageProcessorOutput scratch-resource methods unconditionally abstract now that adding [Abstract] no longer requires a compatibility guard.

Remove the corresponding xtro exceptions because the managed protocol now matches the native required members.
