Metal Graphics API Usage?

What would be the platform requirements?
Metal requires iOS 8 and an >A7-based device (iPhone 5S,6,6s, iPad Air, Retina iPad Mini etc..).

If I ship an app to iTunes with ONLY Metal graphics API selected, will it just say, "Compatible with iPhone 5S and above? and iOS 8? In the app store?

Is this possible? Does apple/iTunes determine compatibility based off of your chosen graphics API?

I've built my game to utilize the Metal API with my lighting, so any lower API's don't show my lighting properly.

Any feedback would be awesome

 

If you want to restrict your app to metal only devices you have to edit "required device capabilities" in the info.plist file through Xcode.

Here is the apple ref:

@sfjohansson Thanks. I'm looking at my info.plist file, and it states, "Required device capabilities" ->
item 0: armv7
item 1: metal

As long as I have this, then I'm good?

 

Yes. you're all good.

You can check out the device compatibility list here to see which devices your game will support...

 

Great, thank you
