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

michaelevensen / PagingCollectionViewController.swift
Last active April 10, 2024 08:46
An example of perfectly paging horizontal UICollectionViewController with overflowing cells. Works great with Storyboard — no need to set any specific attributes, just add this Class to the Controller and set your desired size for the cells like you would normally.
import UIKit
private let reuseIdentifier = "Cell"
class CollectionViewController: UICollectionViewController {
/* Custom scrollView for paging */
let pagingScrollView = UIScrollView()
/* Return item size */
