Here is solution

When you are working on an iOS application say iPhone or iPad but you have selected wrongly

"My Mac 64 bit" you will get this error enter image description here

So select proper application type say

iphone Retina(3.5 inch) device iphone Retina(4 inch) iphone Retina 64 bit

ipad ipad retina

etc then you will not get this error.

This can also commonly happen when you copy/duplicate classes. Make sure you don't have any constants defined in your duplicated class that may be defined elsewhere, etc.

The actual error is right there in front of you. It appears that your link phase is failing due to a duplicate symbol: FlightsViewController. You've probably defined this twice, or perhaps you've linked it into a library as well as into your main build.
