Finding Altitude in Swift

Question

I've been having trouble finding a way to get the altitude of the device. Could someone give me a pointer or put together a short script that gets the altitude of the device and prints it? Only in swift. Thanks!

Keep in mind that the GPS altitude is very inaccurate. You may expect jumps of +/- 10m for the same location. – Aminaamine

Good point, guess this isn't what I'm looking for then. Thanks for your time. – Eastnortheast

Import CoreLocation

import CoreLocation

Create a locationManger variable

var locationManager:CLLocationManager = CLLocationManager()

Initialize and start updating location

override func viewDidLoad() {
    super.viewDidLoad()
    self.locationManager = CLLocationManager()
    locationManager.requestWhenInUseAuthorization()
    self.locationManager.delegate = self
    self.locationManager.distanceFilter = kCLDistanceFilterNone
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    self.locationManager.startUpdatingLocation()
}


func locationManager(manager: CLLocationManager!, didUpdateToLocation newLocation: CLLocation!, fromLocation oldLocation: CLLocation!) {
   var alt = newLocation.altitude
   println("\(alt)")
   manager.stopUpdatingLocation()
}

Don't forget to include the NSLocationAlwaysUsageDescription key in your info.plist otherwise the location services will not work on iOS 8. – Aminaamine
