CAMetalDrawable in MTKView is nil in when running on the iOS simulator. So I can't render on screen...

Using Xcode 11 GM, with Metal support in the simulator.

Any idea why metalView.currentDrawable would be nil?

Update:

Solved, using macOS Catalina with the new iOS 13 simulator.

Are you setting the deployment target to iOS 13? – trojanfoe Sep 16 '19 at 13:50
What is the value of `metalView.device`? – warrenm Sep 16 '19 at 21:47
`MTLCreateSystemDefaultDevice()` returns `nil` on an app with deployment target of iOS 13, tho my framework with the code has a deployment target of iOS 11... – Heestand XYZ Sep 18 '19 at 13:55
this must be why: https://stackoverflow.com/a/57912423/4586652, I need Catalina... – Heestand XYZ Sep 18 '19 at 13:59
Correct, Metal support in Simulators requires Catalina. – russbishop Oct 12 '19 at 04:08
