IOS 9 Error Domain=kCLErrorDomain Code=0 "(null)"

Please try this :

Go to :

• Product -> Scheme -> Edit Scheme -> Options -> Allow Location Simulation must be checked and try providing a default location, don't leave it set to "none"

EDIT : As mentionned in the comments, also restart Xcode and you're done !

Hope this helps.

In XCode 11.5 and up...

Open your Simulator:

Features => Location => CustomLocation
