QuartzCore/CAMetalLayer.h file not found

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?

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).

Please choose the iPhone Device rather than simulators.

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

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

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