From b261ad4181e064e65c1d471bf28004b80b89297a Mon Sep 17 00:00:00 2001 From: Alex Soto Date: Thu, 9 Apr 2026 19:11:23 -0400 Subject: [PATCH 1/7] Add C# bindings for the new ARKit C API on macOS 26.0 Bind the new ARKit C-style API (ar_* functions) introduced in macOS 26.0. These are OS_OBJECT-style types using ar_retain/ar_release for lifecycle management, following the same patterns as Network (NW*) and Security (SecCertificate2, SecIdentity2) frameworks. New types (guarded with #if __MACOS__): - ARObject: Base class with ar_retain/ar_release (like OSLog with os_retain) - ARAnchor, ARTrackableAnchor: Anchor types with transform/ID/timestamp - ARAuthorizationResult, ARAuthorizationResults: Authorization query results - ARDataProvider, ARDataProviders: Data provider management - ARSession: Session creation/run/stop with state change callbacks - ARDevice: Device handle for session creation - ARDeviceAnchor: Device pose tracking with query status - ARWorldTrackingConfiguration: World tracking setup - ARWorldTrackingProvider: World tracking with device anchor queries - ARError: Error handling with CFException conversion - 7 enums: ARAuthorizationStatus, ARAuthorizationType, ARDataProviderState, ARDeviceAnchorQueryStatus, ARDeviceAnchorTrackingState, ARSessionErrorCode, ARWorldTrackingErrorCode 17 NUnit tests in tests/monotouch-test/ARKit/ARObjectTest.cs exercise object lifecycle, collection operations, P/Invoke correctness, and enum values. All tests pass on macOS, iOS, tvOS, and Mac Catalyst.

all ObjC ARKit types. However, only the new C API types exist on macOS - the ObjC types (ARAnchor, ARSession, ARCamera, etc.) do not. Add [NoMac] to all 97 ObjC type declarations (interfaces, enums, delegates) in arkit.cs to prevent incorrect macOS availability. Also add [UnsupportedOSPlatform("macos")] to ARSkeleton.CreateJointName to match its parent type's availability.

Remove redundant _stateChangeHandler field in ARSession - the GCHandle already keeps the handler alive. 2. Add XML docs to ARObject.Retain() and ARObject.Release(). 3. Add [NativeName] attributes to all 7 enums so xtro can detect them automatically. Remove 7 enum lines from macOS-ARKit.ignore. Keep the ar_error_domain field in ignore since [ErrorDomain] is a bgen-only attribute not available in manually compiled code. 4. Free GCHandle after base.Dispose() in ARSession to avoid a race where the handler is called while the native object is still alive. 5. Expand test coverage from 17 to 27 tests: add ARDeviceAnchor OriginFromAnchorTransform/Timestamp/IsTracked/Dispose tests, ARDataProviders Dispose test, ARAuthorizationStatus enum values, ARDeviceAnchorQueryStatus/TrackingState enum values, and handler delegate compile-time verification.

A freshly created ARDeviceAnchor returns the identity matrix, and the element-by-element comparison confirms all 16 float values are marshaled correctly. This addresses the review concern that the previous test accepted any return value and wouldn't catch simd marshaling issues.

NMatrix4 has 16 individual float fields and is not recognized as HVA by the .NET runtime, which expects the return via the x8 pointer register instead — resulting in garbage values. Fix by introducing an internal SimdFloat4x4 struct with 4 Vector4 fields (128-bit SIMD type on ARM64) that .NET correctly classifies as HVA. The P/Invoke returns SimdFloat4x4 and is then reinterpreted as NMatrix4 via pointer cast, since both types share an identical 64-byte column-major memory layout. Also update the monotouch-test to assert finite values rather than identity, since a freshly created ar_device_anchor_t initializes its transform to zeros (not identity) before being populated by world tracking.
