How to set image in circle in swift

How can i make i circle picture with swift ?

My ViewController :

import UIKit
import Foundation

class FriendsViewController : UIViewController{

@IBOutlet weak var profilPicture: UIImageView!

override func viewDidLoad() {
super.viewDidLoad()
profilPicture = UIImageView(frame: CGRectMake(0, 0, 100, 100))
}
}

My `profilPicture = UIImageView(frame: CGRectMake(0, 0, 100, 100))` do nothing ..

Exemple:

[To see links please register here]

extension UIImageView{

// Round Image
func roundCorner() {
self.layer.masksToBounds = true
self.layer.borderWidth = 1.0
self.layer.borderColor = UIColor.clear.cgColor
self.layer.cornerRadius = self.frame.size.width/2
}
}

import UIKit

class 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 UIKit

extension UIImageView {

func makeRounded() {

layer.borderWidth = 1
layer.masksToBounds = false
layer.borderColor = UIColor.black.cgColor
layer.cornerRadius = self.frame.height / 2
clipsToBounds = true
}
}

That is all you need....

For Rounded Image, Only following code would be enough in Extension:

self.layoutIfNeeded() // in case of **autolayout**(mentioned by Tom Spee in the comment).

And also make sure the property of UIImageView **contentMode** should be set correctly to get the result.
In my case it is:

imageView.contentMode = .scaleAspectFit


extension UIImageView {
func setRounded() {
self.layoutIfNeeded()
self.layer.cornerRadius = self.frame.height / 2
self.clipsToBounds = true
}
}

imageView.layer.cornerRadius = imageView.frame.height/2
imageView.clipToBounds = true

struct CircleImage: View {
var image: Image

var body: some View {
image
.clipShape(Circle())
}
}

This is correct for `SwiftUI`

// code to make the image round


import UIKit

extension UIImageView {
public func maskCircle(anyImage: UIImage) {


self.contentMode = UIViewContentMode.ScaleAspectFill
self.layer.cornerRadius = self.frame.height / 2
self.layer.masksToBounds = false
self.clipsToBounds = true




// make square(* must to make circle),
// resize(reduce the kilobyte) and
// fix rotation.
// self.image = prepareImage(anyImage)
}
}



// to call the function from the view controller

self.imgCircleSmallImage.maskCircle(imgCircleSmallImage.image!)

This way is the least expensive way and always keeps your image view rounded:

class RoundedImageView: UIImageView {

override init(frame: CGRect) {
super.init(frame: frame)

clipsToBounds = true
}

required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)

clipsToBounds = true
}

override func layoutSubviews() {
super.layoutSubviews()

assert(bounds.height == bounds.width, "The aspect ratio isn't 1/1. You can never round this image view!")

layer.cornerRadius = bounds.height / 2
}
}

The other answers are telling you to make views rounded based on frame calculations set in a `UIViewController`s `viewDidLoad()` method. **This isn't correct**, since it isn't sure what the final frame will be.

Based in the answer of @DanielQ

**Swift 4 and Swift 3**

import UIKit

extension 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()

For **Swift 4**:

import UIKit

extension UIImageView {

func makeRounded() {
let radius = self.frame.width/2.0
self.layer.cornerRadius = radius
self.layer.masksToBounds = true
}
}
