Issue getting didUpdateToLocation in CLLocationManager to trigger

I have a basic app from Whereami (iOS Programming by J Conway & Hillegass)

I am trying to see the location in the console but its not triggering the method


- (void)locationManagerCLLocationManager *)manager
didUpdateToLocationCLLocation *)newLocation
fromLocationCLLocation *)oldLocation
{
NSLog(@"%@", newLocation);
}


the didFinishLaunchWithOptions method looks like this:

- (BOOL)applicationUIApplication *)application
didFinishLaunchingWithOptionsNSDictionary *)launchOptions
{
[locationManager = [[CLLocationManager alloc] init];

[locationManager setDelegate:self];

[locationManager setDistanceFilter:kCLDistanceFilterNone];

[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];

[locationManager startUpdatingLocation];

self.window.backgroundColor = [UIColor blueColor];


_rootViewController = [[UIViewController alloc] init];
self.window.rootViewController = self.rootViewController;


[[self window] makeKeyAndVisible];
return YES;
}


Can anyone tell me please why the didUpdateToLocation method doesn't get called? I have a breakpoint in it and it doesn't go in there.

Thank you
