I am unable to get the Metal Performance HUD to toggle on/off on command on iOS 16+.
I AM able to get it to display permanently by setting user preferences, but that is not useful for my needs.
I have been referencing the presentation video: https://developer.apple.com/videos/play/tech-talks/110339/
I've attached my mm file. I've proven it to reliably execute by hitting set break points.
I've also attached a screen shot of my info.plist using MetalHUDEnabled=YES.
Note that when it is displayed I see the HUD say it is in composite mode. I'm not sure if that is creating an issue or not.
Also note that I am working in Unity and using this plugin as a superior toggleable FPS counter.
Am I missing something? Or is this feature just not working as advertised yet?
After receiving support from Unity, we discovered that the info.plist row should actually be "MetalHudEnabled=YES".
The official presentation video says to use "HUD" in all caps but that is not true.
With this I am able to toggle the Metal Performance Hud on/off on command from my program.
Hopefully this post helps anyone else attempting the same functionality.
