How to get the current MKCoordinateRegion from a MapCameraPosition
Struggled with this a bit, so figured I would write how I did this.
Goal to achieve: Get the MKCoordinateRegion
of the map I’m looking at.
What I tried and did not work:
struct MapSearchView: View {
@State private var position = MapCameraPosition.automatic
@State private var mapRegion: MKCoordinateRegion = .init()
var body: some View {
Map(position: $position)
.onChange(of: position) {
print(position.region)
}
}
}
This would always print nil
even though it’s supposed to be the current region.
What I ended up getting to work:
struct MapSearchView: View {
@State private var position = MapCameraPosition.automatic
@State private var mapRegion: MKCoordinateRegion = .init()
var body: some View {
Map(position: $position)
.onMapCameraChange { mapCameraUpdateContext in
mapRegion = mapCameraUpdateContext.region
}
}
}
I had to use the specific onMapCameraChange
to get the region and then update a state variable. I can then use that however I want.
