Getting the coordinates from the location I touch the touchscreen

Question

I try to get the coordinates from the location where I hit the touchscreen to do put a specific UIImage at this point.

How can I do this?

Answer 1

For SwiftUI I created a new swift file called HostingController.swift

import Foundation
import UIKit
import SwiftUI

class HostingController: UIHostingController {

    override func touchesBegan(_ touches: Set, with event: UIEvent?) {
        if let touch = touches.first {
            let position = touch.location(in: view)
            print(position)
        }
    }
}

Then I changed the following lines of code in the SceneDelegate.swift

window.rootViewController = UIHostingController(rootView: ContentView())

to

window.rootViewController = HostingController(rootView: ContentView())

SwiftUI is basically wrapped in a ViewController via the UIHostingController. At least thats how I think it is.

I hope this helps!
