Xcode Version 5.1 (5B130a)
After updating command line tools, Xcode and my phone's IOS to 7.1, I can no longer build a project even when creating from scratch.
I get about 12 errors, some related to plugins:
ld: warning: ignoring file /Users/me/Library/Developer/Xcode/DerivedData/project/Build/Products/Debug-iphoneos/libCordova.a, missing required architecture arm64 in file /Users/me/Library/Developer/Xcode/DerivedData/project/Build/Products/Debug-iphoneos/libCordova.a (2 slices)
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_CDVPlugin", referenced from:
Lot's of Apple Mach-O Linker errors.
