I’ve recently upgraded my project to UE4.11 and can no longer compile on OSX El Capitan with Xcode 7.3. I’m using the binary/launcher version of the engine.

Every file in my project generates the following error:

error: '_getUObject' marked 'override' but does not override any member functions

Each file is also generating another error `Unexpected namespace name ‘MyProject’: expected expression, with the following trace:
