[iOS] simulator fails to launch with "gfx device initialization failed" error



Reproduction steps:
1. Create a new project
2. Switch build target to iOS
3. Add a Scene to build
4. Go to Player Settings (Edit -> Project Settings -> Player)
5. Add OpenGLES2 or OpenGLES3 graphics API
6. Switch target SDK to Simulator SDK
7. Build the project
8. Run and build it using Xcode with a simulated device (iPad or iPhone)

Expected result: the project builds and runs successfully
Actual: the project fails to launch with error "-> applicationDidBecomeActive() GfxDevice: creating device client; threaded=1 gfx device initialization failed"

Reproducible with: 2017.4.38f1, 2018.4.19f1, 2019.2.21f1, 2019.3.6f1, 2020.1.0a11
Not reproducible with: 2020.1.0a12, 2020.1.0b1
Could not test with: 2020.2 stream due to errors regarding menu item in the console when building in Unity, 2019.1, early 2019.2 because of multiple errors when building in Xcode ("previous definition metal support")

1. Sometimes the application does not quit automatically
2. This issue is fixed in 2020.1 stream (Fix version 2020.1.0a12)

  1. Resolution Note (fix version 2019.3):

    Fix Backported to 2019.3.10f1, 2019.4.22f1, does not reproduce in 2020.1, 2020.2 streams
