Get a list of coordinates from a MKPolyline / MKRoute

MKMultiPoint+Ext.swift

public extension MKMultiPoint {
    var coordinates: [CLLocationCoordinate2D] {
        var coords = [CLLocationCoordinate2D](repeating: kCLLocationCoordinate2DInvalid,
                                              count: pointCount)

        getCoordinates(&coords, range: NSRange(location: 0, length: pointCount))

        return coords
    }
}

// Given a MKRoute, you can just do:
// route.polyline.coordinates

Thanks, good reminder of being swifty and having bester code.

Suggestion: Making the extension off of MKMultiPoint as both MKPolyline and MKPolygon are subclasses of MKMultipoint and can benefit from this extension.

@KennethFra - fair point! Thanks for that note.

Awesome job! Thanks! :)

This helped me a lot, thank you!

This is great, thank you!

Thanks for this code. Just what I needed. Working on get coordinates out of a geoJSON geometry object

Also wanted to add a thanks, still needed in April of 2022. Maybe WWDC22 we'll get some swiftui and mapkit improvements!

Thanks for this code, It's just for me. Great
