hi friends,
im trying to download .dll (c#script) file to ios ,but when i build its in xcod its show some error like this …

(Filename: /Applications/buildAgent/work/d3d49558e4d408f4/artifacts/iPhonePlayer-armv7Generated/UnityEngineDebug.cpp Line: 53)

Non platform assembly: data-0x15c7be00 (this message is harmless)
Failed to load AOT module ‘data-0x15c7be00.dylib’ in aot-only mode.
if any one face this proble before and solve.please help…

Is the DLL a .NET DLL? Was it compiled from Visual Studio or Mono Develop? What version of .NET does it target? Also, what stripping level (if any) are you using?

Thanks for your reply…
