ILocationProvider

Geoposition source interface that the platform implements.

Methods
func setCallbacks(
	locationCallback: LocationCallback?,
	availabilityCallback: AvailabilityCallback?
)

Set the callback functions to update the current geoposition and change the availability of the geoposition source. Calling this method again overwrites the previously set callback functions. If both parameters are nil, geoposition update tracking must be disabled.

Parameters
locationCallback
LocationCallback?

Updates the current geoposition. If the provider is available ( calling availabilityCallback returns true), this source always delivers a valid geoposition. A valid geoposition is a geoposition in which all fields have the current value at the time it was sent to this channel (i.e. if the accuracy of the geoposition >= half the length of the Earth's equator, the geoposition is valid for any of the correct coordinates specified in it). If the accuracy value <= 0, the position is considered unreliable even if isAvailable == true. See the CLLocationManagerDelegate.locationManager(didUpdateLocations:) method.

availabilityCallback
AvailabilityCallback?

Changes the availability of the geoposition source. If this function is called with the value true, all subsequent locationCallback calls will contain a valid (up-to-date) geoposition. Even if tracking of geoposition changes is unavailable, the ILocationProvider implementation may send a new geoposition, but it will be considered unreliable. See the CLLocationManagerDelegate.locationManager(didFailWithError:) method.

func setDesiredAccuracy(_ accuracy: DesiredAccuracy)

Sets the desired accuracy of the positioning. If the device cannot return a location with the desired accuracy, it may return a location with a lower accuracy. If the platform does not provide a method with similar functionality, this method must have an empty implementation.
See the CLLocationManager.desiredAccuracy method and \ .

Parameters
accuracy
Properties
var lastLocation

Best currently known geoposition. If no currently known geoposition is available, nil is returned. The geoposition returned by this method may not be valid (see setCallbacks). This method must request the best currently known geoposition from the system and return it even if it is outdated and/or does not meet the required accuracy. If the platform API does not provide a method with similar functionality, this method must always return nil.
See the CLLocationManager.location method.
