Certainly, you can utilize the features and technologies associated with Metal.
However, I would like to emphasize that while I am not proficient in Metal, I possess a certain level of understanding of the technology. To the best of my knowledge, Metal appears to be incompatible with virtual machines(Simulator) and necessitates the execution on a physical machine. Nevertheless, I am uncertain about this assertion. If this is indeed the case, please ensure that you request the reviewer to utilize Playground for the execution of your application (there is a specific option available in the form). This option should be chosen instead of Xcode, as the execution of your application using Xcode will result in the utilization of a virtual machine. However, if Metal is indeed compatible with virtual machines, please disregard this paragraph.
I trust that this information will be beneficial to you.
