public interface MPSDeviceProvider
When a object is initialized by a NSCoder, it calls -initWithCoder:, which is missing the necessary MTLDevice to correctly initialize the MPSKernel, or MPSNNGraph. If the coder does not conform to MPSDeviceProvider, the system default device will be used. If you would like to specify which device to use, subclass the NSCoder (NSKeyedUnarchiver, etc.) to conform to MPSDeviceProvider so that the device can be gotten from the NSCoder.
See MPSKeyedUnarchiver for one implementation of this protocol. It reads files prepared with the NSKeyedArchiver and allows you to set the MTLDevice that the unarchived objects use.
