Difference between different Location Requesting Types

WHat I read in document seems to answer:

func requestWhenInUseAuthorization()

Requests permission to use location services while the app is in the foreground.

func requestAlwaysAuthorization()

Requests permission to use location services whenever the app is running.

So, if you want to receive background update, you need to request always.

In addition, you need to set allowsBackgroundLocationUpdates:

Apps that want to receive location updates when suspended must include the

UIBackgroundModes

key (with the

location

value) in their app’s

Info.plist

file and set the value of this property to

true

. The presence of the

UIBackgroundModes

key with the

location

value is required for background updates; you use this property to enable and disable background updates programmatically. For example, you might set this property to

true

only after the user enables features in your app where background updates are needed.

When the value of this property is

false

, apps receive location updates normally while running in either the foreground or background based on its current authorization. Updates stop only when the app is suspended, thereby preventing the app from being woken up to handle those events.

The default value of this property is

false

. Setting the value to

true

but omitting the

UIBackgroundModes

key and

location

value in your app’s

Info.plist

file is a programmer error.

Hope that answers.

Thanks for your answer, that helped me a lot.

Is it also right, that if the app ask for location access and the user gives only "WhenInUse" access you can access the location in background anyway but a blue indicator is shown on the status bar (the allowsBackgroundLocationUpdates property has also to be set on true, i think) when the app is in background. If the user gives "Always" access the blue indicator is not shown when the app is in the background and the location is accessed.

Is this the right behavior? I could get this behavior with a test app and only using the "requestAlwaysAuthorization" method for requesting.

Thanks in advance
