Answer 1

import UIKit

class ViewController: UIViewController {
  @IBOutlet weak var image: UIImageView!

  func makeRounded() {

    image.layer.borderWidth = 1
    image.layer.masksToBounds = false
    image.layer.borderColor = UIColor.blackColor().CGColor
    image.layer.cornerRadius = image.frame.height/2 //This will change with corners of image and height/2 will make this circle shape
    image.clipsToBounds = true
}

Happy Coding
