I hope this helps . You do not want to assume that the location manager will have a valid location. Nor do you want to have a while loop or a timer, waiting for it.
What you want to do is start location services in viewDidLoad, request permission for location services with requestWhenInUseAuthorization or requestAlwaysAuthorization (ensuring that the appropriate plist string for NSLocationWhenInUseUsageDescription or NSLocationAlwaysUsageDescription keys have been set) and then wait for didUpdateLocations method of the CLLocationManagerDelegate to be called. Only then would you have a valid location.

I wish did fix the issue. Whenever you call [locationManager startUpdatingLocation];, this will give you the current location. So, when you call this function again it will give you new location.

Swift 4 CLLocationManager question: Can I use the location, which is got from CLLocationManager, in ViewDidLoad function

should help you out You can't print your location in viewDidLoad because it is an asynchronous method you need to wait until it is fetched. You need to stop updating your location using stopUpdatingLocation() when you get your location. To do it I prefer to use following.

code :

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if let location = locations.last {
        initialLocation = CLLocation(latitude: location.coordinate.latitude,
                                     longitude: location.coordinate.longitude)
        print(initialLocation)
        getLocation?(initialLocation)
    }
    manager.stopUpdatingLocation()
}

var getLocation: ((_ location: CLLocation) -> (Void))?

 getLocation = { location in
        print(location)
    }

getLocation?(initialLocation)

Should an app start location tracking in order to get ANY last known location from CLLocationManager?

wish helps you First you should check if your locationManager has a, let's say, 'static' location pre-saved.
If it does, you're done.

CLLocationManager stops updating location in background even with flag "location" set in application propertie

Hope this helps In iOS5 be sure to use locationManager:didUpdateToLocation:fromLocation:. It is the method that keeps your app requesting location services even in the background. In iOS6 you should use locationManager:didUpdateLocations: as locationManager:didUpdateToLocation:fromLocation: is deprecated in iOS6.
In iOS6 make sure you add the following or else location services will be turned of when the system thinks you are not using it:
