Mapping Properties
Sample app that demonstrates dynamically updating UIMapKit pins when user scroll / zooms the map. Written in Swift 5.
Default view - one property is displayed individually, others are close enough to other properties that they are displayed as a group to prevent clutter
Partially zoomed in - some properties have regrouped, or left group
Zoomed in - all properties shown individually
