When I try to import the
'WatchConnectivity/WatchConnectivity.h' file not found
Xcode version 6.4 doesn't support watchOS 2 SDK, which is what would be required to use
This is why the
#import returns a 'file not found' error, as that particular header file (and framework) didn't exist prior to watchOS 2.
You would have to upgrade to Xcode version 7.0 or higher, if you want to use
WatchConnectivity or other watchOS 2 features.
