问题:

I need to fetch the user current location for the WatchKit App in watchOS 2. How do I do this?

The other answers are incorrect. You can request location directly on the watch for watch OS2. The available method is called requestLocation. It allows you to request a single location update.

E.g.

#import <CoreLocation/CoreLocation.h>
@interface className : WKInterfaceController<CLLocationManagerDelegate>

Then where you want to request location:

self.locationManager = [CLLocationManager new];
self.locationManager.delegate = self;
[self.locationManager requestWhenInUseAuthorization];
[self.locationManager requestLocation];

Then you will get a single callback in one of the following CLLocationManagerDelegate methods.

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
    // Callback here with single location if location succeeds
}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
    // Error here if no location can be found
}
