Trying to call [MTLDevice newTextureWithDescriptor:iosurface:plane:] on an Apple Silicon mac, where the descriptor specifies MTLStorageModeShared, I am getting a failed assertion error:

-[MTLDebugDevice newTextureWithDescriptor:iosurface:plane:]:2387: failed assertion `Texture Descriptor Validation
IOSurface textures must use MTLStorageModeManaged

I don't really understand why we have this limitation, MTLStorageModeShared textures are supported on Apple silicon (despite the documentation in https://developer.apple.com/documentation/metal/mtldevice/1433378-newtexturewithdescriptor?language=objc which claims overwise.

The issue is still present with MacOS 13.1 RC.

It is possible to have any update from Apple, please?

This worked for me

You should be able to work around it by turning off Metal Validation in Scheme -> Edit Scheme -> Run -> Diagnostics -> Metal API Validation

It's working for debugging, not for production and final users.

Juste tested MacOS 13.2, same issue.

Seems like disabling API Validation option when running it fixes it:)
