QuartzCore/CAMetalLayer.h file not found

Question

I try to check out the new Samples from the new Metal API for iOS. When i download the code an open it in the XCode 6 Beta I'm getting the following error message:

QuartzCore/CAMetalLayer.h file not found

Do i need to add some other files or am I missing something else? The Metal API should be available in OSX 10.9.3.

Is there any need to upgrade to Yosemite 10.10 Beta to run these examples?

Answer 1

Reason behind this error is it only works in device having A7+ chip, simulator will not work for this.

Answer 2

Try switch the device target to your iOS device (a7+), Metal is not available in iOS simulators.

Answer 3

CAMetalLayer is now supported in the iOS 13 / tvOS 13 simulators when running on macOS 10.15. (It is always present but won't be functional if you're running on macOS Mojave).
