startMonitoringSignificantLocationChanges not working in swift

Question

I'd added CLLocationManager in my app using Swift in the AppDelegate file.

In the Appdelegate.swift file,

import CoreLocation
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {
var locationManager: CLLocationManager!

In the didbecomeActive method:

func applicationDidBecomeActive(application: UIApplication) {
    if((locationManager) != nil)
    {
        locationManager.stopMonitoringSignificantLocationChanges()
        locationManager.delegate = nil
        locationManager = nil
    }
    locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.activityType = CLActivityType.OtherNavigation
    locationManager.requestAlwaysAuthorization()
    locationManager.startMonitoringSignificantLocationChanges()
}

If I use startUpdatingLocation, didUpdateLocations method gets called, but not for startMonitoringSignificantLocationChanges.

Why it's not getting called for startMonitoringSignificantLocationChanges. I'm testing this in ios simulator. I don't know how to check in device.

Answer 1

It's working, but it's really hard to trigger significant location changes - it usually happens when the device is changing cell towers - I don't think it's possible to do with the simulator.

You'd probably have to get on a bike/car and travel AT LEAST a few kilometres.

There's a trick you can use though, that will trigger significant location change:

Switch Airplaine mode in your iPhone on and off with a few second intervals repeatedly, it should trick the device into thinking that it changed cell towers and trigger the significant location change.

Answer 2

In your simulator, goto Debug->Location->Custom and change location, then test it.
