I have refered to How to drag UIImageView using touches method

import UIKit


class ViewController: UIViewController {

    @IBOutlet var imgView: UIImageView!
    var imgMarker:UIImage?
    var location = CGPoint()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

        imgMarker = UIImage(named: "marker.png")
        imgView.image = imgMarker
    }

    override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?){
        if let touch = touches.first {
            location = touch.location(in: self.view)
        imgView.center = location

        }
    }
