My App tracks your location. With iOS8 I had to change how it was starting location services. I got this working with
[self.locationManager requestAlwaysAuthorization];
and adding NSLocationAlwaysUsageDescription to the plist file.
The app now gets your location when run on a device, but not in the simulator.
Any clues on how to get this to work in the simulator? It used to!!!
In the iOS Simulator, select Debug > Location, then choose your location.
I decided to post this in case anyone else had the same issue. I got the simulator to respond to location changes again by adding NSLocationWhenInUseUsageDescription back into the plist file. I had removed it since my app needs the Always permission instead of WhenInUse. By adding this back to the plist the simulator is now happy. I did not have this issue on the physical device, just the simulator.
