Unity Facebook SDK 7.0.2 Failed to compile in iOS

I am currently using Unity 5.0.2 and Unity FB SDK 7.0.2 Beta, which occur during iOS compilation.

Errors:

If I use IL2CPP for compilation, it will show a similar error with some additional information

Does anyone know how to fix this?

If you find that it is fbUnityInterface.hmissing from your Xcode project, try the following:

Locate the file in your Unity project and select the iOS check box in the "Select platforms for plug-in" field in the inspector.

Without this flag, Unity may not know that the .h file should be included in the assembly, since it only refers to a .mm file that Unity does not parse.
