Finding the pixel location of the touch in Swift:

guard let image = imageView.image else {
    return
}

let x = image.size.width / imageView.frame.size.width
let y = image.size.height / imageView..frame.size.height

// Assuming touchLocation is CGPoint received from Touch event
var touchLocation: CGPoint
let locationInImageView = CGPoint(x: touchLocation.x * x, y: touchLocation.y * y);
