device
The Metal device responsible for the layer’s drawable resources.
Declaration
var device: (any MTLDevice)? { get set }Discussion
This property determines which device object Metal uses to create its MTLTexture objects. When you retrieve a drawable object and its associated texture, you must render to the texture using the same device object.
The default value is nil—you must set the device for a layer before rendering.
