Mistake:

 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo: can't figure out the architecture type of: /Users/samichaudry/Library/Developer/Xcode/DerivedData/CartoonQuiz-bqmbxfcdkldmbqawgrfmjtebypuk/Build/Intermediates/CartoonQuiz.build/Debug-iphoneos/CartoonQuiz.build/Objects-normal/armv7/CartoonQuizCommand /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo failed with exit code 1 

Answer 1

Is there a file referenced by lipo, or is it null?

Try changing the assembly target to the simulator assembly, clean and restart.

Answer 2

Removing the armv7 architecture, leaving armv7s (found here ) did it for me.

Answer 3

I had to add i386 to my valid architectures to get this to work.
