How to fit bounds for coordinate array with google maps sdk for iOS?

Question

How to fit bounds for coordinate array with google maps sdk for iOS? I need to zoom map for 4 visible markers.

Answer 1

We can simplify this quite a bit, with code such as the following:

extension Array where Element: GMSMarker {
  func encompassingCoordinateBounds() -> GMSCoordinateBounds {
    reduce(GMSCoordinateBounds(), { $0.includingCoordinate($1.position) })
  }
}

The call site would like:

let markers = [GMSMarker]()
let encompassingCoordinateBounds = markers.encompassingCoordinateBounds()
