Request locations using CLLocationManager in Widget target on iOS 14

I have CLLocationManager working inside a widget. I had to add these two values to the widgets info.plist file:

<key>NSLocationUsageDescription</key>
<string>1</string>

<key>NSWidgetWantsLocation</key>
<true/>

@markdaws Can you help us out with CLLocationManager inside the widget ? I can't seem to get it to call delegate methods.
What I've seen in beta 3 is:

• if I initiate the location manager in the TimelineProvider struct I get an error message in console saying that location manager should be allocated in the main thread not bg thread

• if I initiate it in the View struct of the widget I can see that CLLocationManager is initialised correctly, authStatus code is: "when in use" but still I can't seem to receive the location callbacks

What is you experience like ?

I'm not sure of the best way to use CLLocationManager inside WidgetKit, it would be nice to get a sample from Apple around it showing exactly how we should do it.

To fix the main thread issue, what I did was create a wrapper class that I instantiate in the widget struct that will hold a reference to the CLLocationManager, then on the call to timeline() I create the CLLocationManager instance at that time and store a reference to it in the wrapper, this means it is created on the right thread. If you don't store a reference to this class that lives beyond the call to timeline() the callbacks are never called.

Then, instead of streaming updates from the CLLocationManager instance, I use CLLocationManager requestLocation() to get a one time callback.

Something like this:

LocationWrapper.swift

Code Block swift
final class LocationWrapper {
  var location: CLLocationManager?
	func fetchLocation(completion: @escaping (CLLocation) -> Void) {
		 // call requestLocation(), hook up to callbacks etc.
		 // call completion once you a
	}
}

widget_main.swift

Code Block swift
struct Provider: TimelineProvider {
  var locationWrapper = LocationWrapper()
  public func timeline(with context: Context, completion: @escaping (Timeline<SimpleEntry>) -> ()) {
    if locationManager.location == nil {
      locationManager.location = CLLocationManager()
    }
		locationManager.fetchLocation { location in 
				// call completion, update ui etc.
		}
}

typo in widget_main.swift

Code Block struct Provider: TimelineProvider {
    var locationWrapper = LocationWrapper()
    public func timeline(with context: Context, completion: @escaping (Timeline<SimpleEntry>) -> ()) {
        if locationWrapper.location == nil {
            locationManager.location = CLLocationManager()
        }
        locationWrapper.fetchLocation { location in
            // call completion, update ui etc.
        }
}

Hello everyone!
Has anyone managed to get it working?

I have two entries in Widget's info.plist as @markdaws mentioned.
My location manager wrapper looks this way:

Code Block swift
class WidgetLocationManager: NSObject, CLLocationManagerDelegate {
    var locationManager: CLLocationManager? {
        didSet {
            self.locationManager!.delegate = self
        }
    }
    private var handler: ((CLLocation) -> Void)?
    func fetchLocation(handler: @escaping (CLLocation) -> Void) {
        self.handler = handler
        self.locationManager!.requestLocation()
    }
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        self.handler!(locations.last!)
    }
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print(error)
    }
}

And getTimeline function this way:

Code Block swift
    var widgetLocationManager = WidgetLocationManager()
    func getTimeline(for configuration: SelectPlaceIntent, in context: Context, completion: @escaping (Timeline<Entry>) -> Void) {
        if widgetLocationManager.locationManager == nil {
            widgetLocationManager.locationManager = CLLocationManager()
            widgetLocationManager.locationManager!.requestWhenInUseAuthorization()
        }
        widgetLocationManager.fetchLocation(handler: { location in
            print(location)
            ........
        })
    }

When locationManager.requestLocation() is being called, authorisation status is authorisedWhenInUse, but delegate's method is never being called. What am I missing?
