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

I have Updated on Yosemite, Xcode 6.1. I have updated gem xcodeproj (0.19.4) and cocoapods (0.34.4).

I have resolve my conflict by :

Clearing the Library/Developer/Xcode/DerivedData folder

replace in Target -> Build Settings -> Linking -> Other Linker Flags : $(OTHER_LDFLAGS)

Check in Target -> Build Phases -> Copy Pods Resources : "${SRCROOT}/Pods/Target Support Files/Pods/Pods-resources.sh"
