UE4 4.8.3 not compiling in XCode 3.2.5

I’m able to open UE4 into XCode, make my edits and save, but when I build I get this message, “No launchable executable present at path: /Users/bvc/Desktop/Unreal-Engine-release/Engine/Binaries/IOS/UE4Client.app”. Indeed, I see no such file in the directory. Thanks for advising.

I’m running Mac OS 10.9.5, Mac Pro late 2013 2.7 GHz 12-Core, Intel Xeon E5, 64 GB 1867 MHz DDR 3
