How to create CLCircularRegion using min max geometry bounds

Question

I am working on geofencing where I have to do region monitoring. I am new to geofence topic. I have bounds(min-max coordinates) and geometry data(all location coordinates). From the below bounds, I am creating CLCircularRegion.

"bounds":{"minlat":50.7238333,"minlon":-1.8716499,"maxlat":50.7248599,"maxlon":-1.8683962} 

To initialise CLCircularRegion, we need center and radius. I have calculated centerpoint using the following formula:

center = CLLocationCoordinate2D(latitude: CLLocationDegrees((minLat + maxLat) / 2), longitude: CLLocationDegrees((minLng + maxLng) / 2))

But I am unable to understand how to calculate radius. Any Idea how to do that?

Answer 1

You only have to calculate the distance from center to a point. Use CLLocation method distance(from:). You can create CLLocation instances with latitude and longitude.
