UE4 Xcode 4.8 and 4.9 The Project could not be compiled

Hi
When I create a c++ project with UE4 and Xcode Yosemite UE4 gives me an error
the error is
The Project could not be compiled…
and at the end message
ERROR: UBT ERROR: Failed to produce item: /path/Binaries/Mac/UE4Editor-SetUp.dylib
how can I configure Xcode to ensure that it works well?

ThankYou!
