I have a bunch of these when I compile my watchOS 2 target:
Argument unused during compilation: '-MF /Users/aleck/Library/Developer/Xcode/DerivedData/Couch_to_5k-cmbnzarnwsetiwgngpuzrtdmdkct/Build/Intermediates/Couch to 5k.build/Debug-watchos/Go5k watchOS2 Extension.build/Objects-normal/armv7k/ExtensionDelegate.d'Once for each file in the watch app. Xcode b5, SDK b5 (downloading Xcode b6 now). What's causing this..?
