Bug - Replacements.RemotingServices:CreateClientProxy() in Unity 5.0.1 and Xcode 6

Hi,

I have built my current project with Unity 5.0.1 and Xcode 6 and deployed to a test device. However, when running the first level of the game, I get a strange null reference exception that I don’t get during testing in Editor, Android build or when building for 32-bit (mono rather than IL2CPP). Here is the error message from Xcode during running on the device:

Unloading 32 unused Assets to reduce memory usage. Loaded Objects now: 25672.

Total: 102.572128 ms (FindLiveObjects: 8.138875 ms CreateObjectMapping: 7.412916 ms MarkObjects: 82.381958 ms DeleteObjects: 4.629041 ms)

NullReferenceException: A null value was found where an object instance was required.

(Filename: currently not available on il2cpp Line: -1)

*** end of error message

I don’t use Replacements.RemotingServices.CreateClientProxy() anywhere in my original code. Seems to be specific to il2cpp … especially considering the last line of the message. Can anyone please help me determine whether this is a new issue or has this already been identified? I have not yet opened a bug report. I wanted to get feedback form the community before doing so. Any help would be greatly appreciated … the whole il2cpp process is something that confuses me greatly.

I’m trying to figure things out on my end, obviously. Does anyone know of a full list of functions / methods that are not supported yet in IL2CPP? I presume that there is a script somewhere in my project that is not being converted over properly and that is causing the issue. If I have a full list of currently unsupported commands, I can search for them and make adjustments. Can anyone help?

Try to switch Api Compatibility Level to .NET 2.0 Subset. In my case it works.

Thanks … I did try that but it didn’t help in this case.

Got the same problem!

Same here when I use WWW class. Seems that Coroutine is lost. I have an
Exception: WWW download:The operation couldn’t be completed. (NSURLErrorDomain error -1012.)
My code works well on Android, windows, mac and editor iOS. But on device not.

@TobyKaos

Please try the latest patch release version of Unity. This looks like an error that was recently corrected.

Any luck? have the same problem with ILCPP + Unity 4.6.4f1. Only on device.

@Mattias-Wargren

It might be worth trying 4.6.5f1 now, as we have made a number of fixes since 4.6.4f1.
