Adjusting map view span to annotiation pins in Swift

Question

I wonder if Swift supports any faster way to do that without implementing arythmetics. I guess adjusting the map span to let user see all the annotation pins is not a rare problem.

I found this: Zooming MKMapView to fit annotation pins? but it's a bit complicated in objective-c and seems to be a vulnerable solution. Did swift developers find any other way(or method) to deal with it?

Thanks in advance

If you can target iOS 7 or above, you can use showAnnotations:animated, and pass in the map view's annotation property.

Thanks! But I'm not sure how to pass the annotations, as an array of them? – theDC Dec 29 '14 at 19:22
Assuming your MKMapView is named `mapView`, I believe you can just past in `mapView.annotations` – Dominic K Dec 29 '14 at 19:27
