A texture handle that can be shared across process address space boundaries.


class MTLSharedTextureHandle : NSObject


MTLSharedTextureHandle objects may be passed between processes using XPC connections and then used to create a reference to the texture in another process. The texture in the other process must be created using the same MTLDevice on which the shared texture was originally created. To identify which device it was created on, you can use the device property of the MTLSharedTextureHandle object.


Identifying the Shared Texture Handle

var device: MTLDevice

The device object that created the texture.

var label: String?

A string that identifies the texture.
