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