iOS Packaging Error: missing UE4Game.stub

When I try to package my project to iOS I get this error:

MainFrameActions: Packaging (iOS): IPhonePackager: IPP ERROR: Failed to find stub IPA 'C:\UE4\Engine\Binaries\IOS\UE4Game.stub'

Full error log.

Any ideas how to fix this? How do I get the UE4Game.stub file?

Hi BenStanley,

Are you still experiencing this iOS packaging errror in later versions of the engine? If this has been resolved, please disregard this message.
