xcode apple mach-o linker errors

Hello,

I have recently completed a mobile iOS application in Unity 5.0.2f1 and built the project. Now, I opened it in XCode 6.3.2 and I get many “apple mach-o linker errors”.

What can I do to fix these errors?

Thank you

I had the same problem.
I made a video to show you how to fix it.
