Docs don't mention that on iOS geolocation needs to be done on a thread with a run loop

I'm new to iOS and expected that calling this inside a suspend function launched in Dispatchers.IO:

val geolocator = Geolocator.mobile()
val geolocatorResult = geolocator.current(priority = Priority.HighAccuracy)

would simply work on iOS just like it does on Android.
It turns out that on iOS it needs to be done like this:

var geolocatorResult
withContext(Dispatchers.Default) {    // [***]
        val geolocator = Geolocator.mobile()
        geolocatorResult = geolocator.current(priority = Priority.HighAccuracy)
}

Otherwise, the app will never return.

There is no mention of these facts in the docs, which can result in great time wasting for people in the same situation like myself.

[***] Using Dispatchers.Main here instead will trigger the warning:
[CoreLocation] This method can cause UI unresponsiveness if invoked on the main thread. Instead, consider waiting for the -locationManagerDidChangeAuthorization: callback and checking authorizationStatus first.
