How to set image in circle in swift

import UIKitclass ViewController: UIViewController {  @IBOutlet weak var image: UIImageView!  override func viewDidLoad() {    super.viewDidLoad()    image.layer.borderWidth = 1    image.layer.masksToBounds = false    image.layer.borderColor = UIColor.black.cgColor    image.layer.cornerRadius = image.frame.height/2    image.clipsToBounds = true}

If you want it on an extension

import UIKitextension UIImageView {    func makeRounded() {        self.layer.borderWidth = 1        self.layer.masksToBounds = false        self.layer.borderColor = UIColor.black.cgColor        self.layer.cornerRadius = self.frame.height / 2        self.clipsToBounds = true    }}

That is all you need....

You can simple create extension:

import UIKitextension UIImageView {   func setRounded() {      let radius = CGRectGetWidth(self.frame) / 2      self.layer.cornerRadius = radius      self.layer.masksToBounds = true   }}

and use it as below:

imageView.setRounded()

Based in the answer of @DanielQ

Swift 4 and Swift 3

import UIKitextension UIImageView {    func setRounded() {        self.layer.cornerRadius = (self.frame.width / 2) //instead of let radius = CGRectGetWidth(self.frame) / 2        self.layer.masksToBounds = true    }}

You can use it in any ViewController with:

imageView.setRounded()
