Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…

Pragmatic programmer checklists in form of Gists.

Architectural Questions

  • Are responsibilities well defined?
  • Are the collaborations well defined?
  • Is coupling minimized?
  • Can you identify potential duplication?
  • Are interface definitions and constraints acceptable?
  • Can modules access needed data—when needed?

Create an MKCoordinateRegion from an array of coordinates. Safely handles coordinates that cross the 180th meridian.
import MapKit
extension MKCoordinateRegion {
init?(coordinates: [CLLocationCoordinate2D]) {
// first create a region centered around the prime meridian
let primeRegion = MKCoordinateRegion.region(for: coordinates, transform: { $0 }, inverseTransform: { $0 })
// next create a region centered around the 180th meridian
