[iOS] [Android] External library generics fail during IL2CPP build
How to reproduce:
1. Open the “ReproProject.zip“ project
2. Open the “SampleScene“
3. Build for Android
Expected result: Build successfully
Actual result: Build fails with several errors
Reproducible with: 2023.2.0a17, 6000.0.61f1, 6000.2.9f1, 6000.3.0b8, 6000.4.0a4
Reproducible environment: macOS 15.7 (M4 Max), Windows 11 (Reporters)
Not reproducible environment: No other environment tested
Notes:
- Building with {{--generic-option=EnableLegacyGenericSharing}} flag also spews out errors
- Reproducible with both Android and iOS builds
Errors without a flag:
{{Error: IL2CPP error for method 'CommonLibs.Swizzle5<T1,T2,T3,T5,T4> CommonLibs.Swizzle5::op_Implicit(CommonLibs.Swizzle5<T1,T2,T3,T4,T5>)'}}
{{Error: IL2CPP error for method 'CommonLibs.Swizzle2<T2,T1> CommonLibs.Swizzle2::op_Implicit(CommonLibs.Swizzle2<T1,T2>)'}}
Errors with a flag:

This issue keeps us from moving up from Unity 2021, so we can't comply with the latest play store requirements and therefore cannot release any new updates. Is it possible to get a time estimate for when this is looked at? Thanks in advance
