how to use MapView from a framework library Xcode8

Question

I created a custom tile service and add it to a mapView then it works fine. then I used the same code and created a framework library with a MapView return type in Xcode 8. then I used a sample test app and import that library to it and I called the method used in library and add it to a mapView. So my problem Is when I call and that method to mapView it displays the MapKit map not my custom map

code used in library

import Foundation
import MapKit
public class mapLib: NSObject{

    public  class func createMap(mapView: MKMapView) ->MKMapView{
        let mapView = mapView
        //custom map URL
        let template = "http://tile.openstreetmap.org/{z}/{x}/{y}.png"
        let overlay = MKTileOverlay(urlTemplate: template)
        overlay.canReplaceMapContent = true
        mapView.add(overlay, level: .aboveLabels)
        return mapView;
    }
}

code used in app

import UIKit
import MapKit
import mapLib
class ViewController: UIViewController {
    @IBOutlet weak var mapV: MKMapView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let view = mapLib.createMap(mapView: mapV)
        mapV.addOverlays(view.overlays)

        //any additional setup after loading the view, typically from a nib.
    }

I need to clarify that the way I'm going to approach would work or any other method to do it :)

You are missing add self as delegate and implement func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer method, you can do this in your library

something like this

import Foundation
import MapKit
public class mapLib: NSObject{

    public  class func createMap(mapView: MKMapView) ->MKMapView{
        let mapView = mapView
        //custom map URL
        let template = "http://tile.openstreetmap.org/{z}/{x}/{y}.png"
        let overlay = MKTileOverlay(urlTemplate: template)
        overlay.canReplaceMapContent = true
        mapView.add(overlay, level: .aboveLabels)
        mapView.delegate = self
        return mapView;
    }
}

extension mapLib : MKMapViewDelegate{

    func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
        if let overlayTile = overlay as? MKTileOverlay{
            let overLayRenderer = MKTileOverlayRenderer(tileOverlay: overlayTile)
            return overLayRenderer
        }

        return MKOverlayRenderer(overlay: overlay)
    }
}

now the app get crashed and says "0__abort_with_payload" – Saneth Chandrasekara Aug 31 '17 at 10:01

then add the delegate and the implementation in your viewController, and try, for me is hard to test your setup @Saneth – Reinier Melian Aug 31 '17 at 11:50
func mapView(_ mapview: MKMapView, rendererFor overlay: MKOverlay) ->MKOverlayRenderer{...}. is there any other way to add this method problem is in it – Saneth Chandrasekara Sep 01 '17 at 10:22

that method is required if you want render custom tiles on your mapView – Reinier Melian Sep 01 '17 at 11:19
I need to put that method somewhere in the library and call it from view controller to display the map – Saneth Chandrasekara Sep 02 '17 at 13:39
