Why my "Allow Location Access" is always turned off when I switch it to on?

Question

Inside Location Services I allow my App to always use location. In viewDidLoad I created a timer which calls my method every 2 seconds:

println("---\(locationManager.location)")

In the beginning I get ---nil, but when I go to the settings and change access to always, and then get back to the app again, I immediately get:

---<+50.06689474,+19.92923662> +/- 165.00m (speed -1.00 mps / course -1.00) @ 28.05.2015, 13:00:39 Czas środkowoeuropejski letni

But once it is printed there is still: ---nil. Why?

This is how I setup locationManager:

private let locationManager = CLLocationManager()

in viewDidLoad() I call the method:

private func setupLocationManager() {
    locationManager.delegate = self
    locationManager.distanceFilter = kCLDistanceFilterNone
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.startUpdatingLocation()
}

NSTimer.scheduledTimerWithTimeInterval(2, target: self, selector: Selector("printLocation"), userInfo: nil, repeats: true)

usually you use the `CLLocationManagerDelegate`: https://developer.apple.com/library/mac/documentation/CoreLocation/Reference/CLLocationManagerDelegate_Protocol/index.html#//apple_ref/occ/intfm/CLLocationManagerDelegate/locationManager:didUpdateLocations: — donmarkusi, May 28 '15 at 11:19
yes, I know, I implemented this, but the methods of delegate are not called... — Bartłomiej Semańczyk, May 28 '15 at 11:20
hard to tell from here. try to debug your code and see if the location manager get deallocated or something... http://stackoverflow.com/questions/11697730/cllocationmanager-startupdatinglocation-not-working — donmarkusi, May 28 '15 at 11:22

The answer how to implement CoreLocation framework in the simplest way in Swift is:

import CoreLocation in the file when you use it
Add framework to Link binary with libraries:

enter image description here

setup private let locationManager = CLLocationManager() and implement CLLocationManagerDelegate with methods:

func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) {

    if status == .AuthorizedAlways || status == .AuthorizedWhenInUse {
        locationManager.startUpdatingLocation()
    }
}

In viewDidLoad setup your locationManager property:

private func setupLocationManager() {
    locationManager.delegate = self
    locationManager.distanceFilter = kCLDistanceFilterNone
    locationManager.desiredAccuracy = kCLLocationAccuracyBest

    if CLLocationManager.locationServicesEnabled() {
        locationManager.startUpdatingLocation()
    }

    if CLLocationManager.authorizationStatus() == .NotDetermined {
        locationManager.requestAlwaysAuthorization()
    }
}

most important!!!! Setup your info.plist file with key NSLocationAlwaysUsageDescription and example value: Turn on your location, we need it:-)
