Xcode 6 linker error - Undefined symbols for architecture armv7

Question

After upgrading to Xcode 6 beta 7 (and now still with Xcode 6 GM) I am unable to link my Swift app. I receive errors such as:

Undefined symbols for archit

Answer 1

1) I face the same problem but just clear the applications from derived data from User/Library/Developer/Xcode/DerivedData and I am able to run the code.

2) In your case may be, it will run by removing armv7 architecture from build settings. And make sure your compiler is Default Compiler in Build Settings.

Thanks I hope this helpful to you and everyone.
