IL2CPP System.InvalidOperationException: Sequence contains no elements when building iOS

Hi

However, I got IL2CPP errors when trying to build iOS app in Unity 5.3.1.p4 and 5.3.2.f1 ( I need to build iOS in Unity 5.3.1p4/5.3.2f1 due to Xcode 7.3 support).

I was able to build iOS app fine in the previous version of Unity, 5.3.1p3.

I was wondering if anyone encounters similar issue and has any pointer?

il2cpp.exe didn't catch exception: System.InvalidOperationException: Sequence contains no elements
