[iOS 12] [Metal] IOAF code 4 error freeze because of tessellation shader
How to reproduce:
1. Build the attached project for iOS (link in description)
2. Build & Run the project to a device via Xcode
3. Keep clicking buttons shown in screenshots (screenshots in edit)
Actual result: The Player freezes and errors are getting spammed.
Expected result: The Player doesn't freeze.
Reproducible with: 2018.4.11f1, 2019.2.10f1.
Devices reproducible with:
- iPhone XR (iOS 12.0)
- iPhone X (iOS 11.3.1)
Devices not reproducible with:
- iPhone X (iOS 13.0)
- iPhone 7 (iOS 12.3.1)
Notes:
- Can't test 2017.4, 2019.3 and 2020.1 as the terrain completely breaks on these versions, but most likely the issue is reproducible there too.

Latest issues
- Articulation Body with 'Revolute' Joint Type has erratic behavior when Upper Limit is set to above 360
- WebGL Player fails to render Scene when Terrain with Detail Mesh is added and WebGPU Graphics API is used
- Inconsistent errors are logged when different types are passed into the Query "Q<>" method in UIToolkit and the ancestor VisualElement is null
- Crash on GetMaterialPropertyByIndex when opening a specific Scene
- Discrepancies in the styling are present when using a TSS file instead of a USS file in custom EditorWindow
Resolution Note (2020.1.X):
This is iOS 12 related, which has decreasing adoption. mostly A7/A8 stick to iOS 12 where tessellation is not a realistic use case, rest of the devices are typically iOS 13 by now
No update from Apple about the filed bug report for workarounds. (will recheck with them)
