Hi @imyellow ,
Are you using any 3rd party plugins that might be outdated?
Cheers,

thanks, no any 3rd party plugins, just select Device SDK in player setting, And build the project to a folder, open the .xcodeproj file, setting the signing profile, Build in Xcode, did not changed anything.

same step, if I select the Simulator SDK, it will have no any errors.

I has use these code integrate with iOS, it work fine on unity 4.x, now on 5.x, is any place need to be modified in the new version?

[DllImport(“__Internal”)]
private static extern void unityToIOS (string str);

update

oh, I found it, I just forget this:

extern “C”
{
void functionName(parameter){
// do something
}
}
