I have a simple CLLocationManager implementation that works in one project but not in my new project.
The code is almost identical but I cannot get the .didUpdateLocations function to call. My code is below. Any ideas why I cannot get the update to work? I'm at a loss, I've build many apps using location services and never seen this situation.
Also I have the three settings in the PLIST set correctly for Privacy-Location Always etc.
There are no errors given, it simply doesn't call .didUpdateLocations
Weather Class
class DarkSkyWeatherController: UIViewController, CLLocationManagerDelegate {
var weatherGetterDelegate: DarkSkyWeatherControllerDelegate?
var locationManager = CLLocationManager()
var lat = String()
var long = String()
func getLocation() {
// Ask for Authorisation from the User.
locationManager.requestAlwaysAuthorization()
// For use in foreground
locationManager.requestWhenInUseAuthorization()
if CLLocationManager.locationServicesEnabled() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers
locationManager.startUpdatingLocation()
}
locationManager.delegate = self
locationManager.requestLocation()
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print(error)
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard let locValue: CLLocationCoordinate2D = manager.location?.coordinate else {return}
print("locations = \(locValue.latitude) \(locValue.longitude)")
lat = String(locValue.latitude)
long = String(locValue.longitude)
getDarkSkyWeather { (fetchedInfo) in
if let myFetchedInfo = fetchedInfo {
self.weatherGetterDelegate?.getMyWeather(weather: myFetchedInfo)
}
}
}
ViewDidLoad in main window
let weather = DarkSkyWeatherController()
weather.weatherGetterDelegate = self
weather.getLocation()
Thanks for looking at this.

Without seeing your full main window code, I bet that the problem is with the scope and lifecycle of your controller:
override func viewDidLoad() {
let weather = DarkSkyWeatherController()
weather.weatherGetterDelegate = self
weather.getLocation()
// Function exits. The weather constant dies off.
// This is why you don't get callbacks.
}
Do the following, instead.
let weather = DarkSkyWeatherController()
override func viewDidLoad() {
weather.weatherGetterDelegate = self
weather.getLocation()
// Function exits, but the weather constant lives on as a field of your main ViewController. You'll get your callbacks now.
}
