We "recently" started getting crashes when taking a satelite map snapshot in app using MKMapSnapshotter. We realized that all crashes have a common denominator that they all happened on iOS 16.
The code that creates the snapshot has been unaltered and working without crashes since 2018 up until the release of iOS 16. This is likely some bug in the SDK.
let options = MKMapSnapshotter.Options()
let location = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)
options.mapType = .satelliteFlyover
options.size = size
options.camera = MKMapCamera(lookingAtCenter: location, fromDistance: distance, pitch: 0, heading: 0)
let snapshotter = MKMapSnapshotter(options: options)
snapshotter.start(completionHandler: completionHandler)
