I'm getting one problem in my Xcode 10 and iOS 12. See my problem is:
GPU Frame Capture
Shader performance data maybe unavailable due to deployment target older than device version
See my screen shot
This is happen in only iOS 12. Which means...
In my Xcode Deployment Target:9.0, In my iPhone OS is : iOS 12 (Now problem came.)
But when i run in Xcode 10 and iOS 11.4 it's fine.
