Thanks for this valuable information. The two new keys work perfectly. The only issue I had was not being notified of the correct drawable size, but I've worked around that by checking for window size changes periodically and specifying the drawable size to the window size multiplied by the native display scale factor.

Perfect, thanks!

Thank you for your very informative post. The WWDC 2022 session was extremely useful. The 2 new keys are great for getting a native window size, however, on my Mac Mini I'm having an issue receiving the correct resolution with the MTKViewDelegate. At first, the drawableSizeWillChange() method is called with the width and height of my monitor reversed (height x width), then instantly called again with a resolution (huge width, small height) that does not match the window at all.

Now there's a crash report though: [Exception Type: EXC_CRASH (SIGKILL (Code Signature Invalid))] [Termination Reason: EXEC 14 Binary with wrong platform]

Thanks for your response eskimo. Here's the output from running the app from the command line: [zsh: killed     /Applications/Kingdom\ Draw.app/Wrapper/IOSGameClient.app/IOSGameClient] [137] A pop-up message also appears stating IOSGameClient can't be opened: IOSGameClient is damaged and can't be opened. Delete IOSGameClient and download it again from the App Store. I then removed the app and re-installed it from TestFlight, but I get the same error. That same application package works fine on IOS so not sure if there's something extra I need to do to have it work on Apple Silicon?

No, there's no crash report listed for it. The app opens and immediately closes (the App shows up in the system tray for a split second then disappears). There's no crash report, and the next message that's in the console about the app after the messages stating its launched is: default 21:15:04.850862+1000 runningboardd [app<com.eternaltechnics.Kingdom-Draw(501)>:6004] termination reported by launchd (0, 0, 256)
