Why is Xcode 6.3.1 giving a bunch of errors?

Question

Apple Xcode

Why is Xcode 6.3.1 throwing a bunch of errors while creating an ipa file? Previously, xcode 5 was installed and there were no such problems. The build was the same in Unity 4.6. What is the problem?. And is it possible for me to go back to xcode 5 which will run on Yosemite 10.10?

There can be anything. Your Unity is trial. Wrong settings in project settings. Accidentally deleted project settings and Unity generated a new one. Unity splash screen problem.
What is the compilation step?
= Lexical analysis.
= Syntactic (grammatical) analysis.
= Semantic analysis.
= Optimization.
= Code generation.
What about libs? Have you installed any plugins or libs? If we take a similar question about artists, then this is something like "Photoshop does not start for me."
