Well in the case of the game we were working on there was no choice other than fork our codebase. No considering the controllers (which is different enough from the consoles) the frame rate of our code base was awfully slow on IOS, so we had to rethink the whole project to target IOS properly. Actually I don't know any unreal game that sucessfuly have been launched on IOS and consoles with the same codebase, and after my experience with the engine I don't think you would like to do that in the sense that you always would like to exploit consoles capabilities. It's a tradeoff very hard to avoid.
