[iOS] Vertex shaders are recompiled at runtime even when using Preloaded Shaders in Project graphic settings
Reproduction Steps:
1. Open User's project
2. Build to iOS
3. Open Xcode project
4. Run Profiler - "Metal System Trace"
5. Inspect the "Shader Compilation" column
6. Notice that vertex shaders has been recompiled at run time
Expected behaviour: Fragment and vertex shaders to get pre-compiled when being specified in a Shader Variant Collection referenced from the graphic settings.
Actual result: Vertex shaders are recompiled at runtime even when using Preloaded Shaders in Project graphic settings
Reproduced on versions: Unity 5.5.2f1, 5.5.3p1, 5.6.0f3, 5.6.0p2, 2017.1.0b1
Reproduced on devices: iPhone 6 iOS 10.3.1

I did notice the same problem with 5.6.1p4. Is there a workaround yet?

This issue is marked as Severity 3: Workaround is possible. Can somebody point me out what's the workaround? We don't know how to avoid recompiling the vertex shaders.
