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?

as far as I know the Metal API is exclusively available in iOS 8, not in OS X — Felix, Jun 10 '14 at 16:42
it seems like the Metal API isn't included in XCode 6, even if i add the Quarz Core Framework for iOS 8. — Brixto, Jun 11 '14 at 19:04
Use either "@import Metal" or "#import . Works for the bundled Game template. — Nicolas Miari, Jun 14 '14 at 10:25

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

The solutions is that you have to use devices(Simulator will not work) that having A7+ chip. – Dharmesh Vaghani Jun 02 '15 at 06:19

I don't think your answer is correct. I am using an iPad Pro 9.7 and I am sure this should work for this device that is high end. – Duck Apr 25 '17 at 14:23
When simulating iOS 13, it will not complain about this. – Chewie The Chorkie Sep 27 '19 at 18:00

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

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).

I think it's an oversight in the iOS Simulator in the beta (up to the current beta 2): /Applications/Xcode6-Beta2.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.0.sdk/System/Library/Frameworks/QuartzCore.framework/Headers/

It's missing the CAMetalLayer.h

But, if you install the beta onto your iOS device, it is there: /Applications/Xcode6-Beta2.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.0.sdk/System/Library/Frameworks/QuartzCore.framework/Headers/CAMetalLayer.h

It's missing because there's no x86/desktop implementation of the Metal API and related classes — RelativeGames, Jul 30 '14 at 10:37

Please choose the iPhone Device rather than simulators.
