UIImageView Rounded Corners in Swift

In this Swift tutorial, you will learn how to make UIImageView corners rounded.

To learn how to programmatically create new UIImage, add it to UIImageView and make it visible in your app, have a look at the following tutorial:

Create UIImage and UIImageView Programmatically

Create UIImage and UIImageView

To make image corners rounded, I will first need to create a new UIImage and set it on to a UIImageView. In Swift code snippet below, I will first do just that.

let catImage = UIImage(named: "cat.jpg")

let myImageView:UIImageView = UIImageView()
myImageView.contentMode = UIView.ContentMode.scaleAspectFit
myImageView.frame.size.width = 200
myImageView.frame.size.height = 200
myImageView.center = self.view.center

myImageView.image = catImage

Make UIImageView Corners Rounded

I will now use the created in the above Swift code snippet UIImageView and will make its corners rounded by changing the value of CALayer cornerRadius and setting the UIImageView clipsToBounds value to true.

myImageView.layer.cornerRadius = 100
myImageView.clipsToBounds = true

Setting the corner radius to 100 will make the image view completely rounded. Try different corner radius like 10, 20, 30, 40 to get image corners of different radius.

To make the image border and visible I will set the borderWidth and the borderColor.

myImageView.layer.borderWidth = 10
myImageView.layer.borderColor = UIColor.lightGray.cgColor

If I put the above code snippet together and run it, my image will look completely rounded.

Complete Code Example in Xcode Playground

Below is a complete code example that you can copy, paste and run in Xcode playground.

import UIKit
import PlaygroundSupport

class MyViewController : UIViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let view = UIView()
        view.backgroundColor = .white
        
        let catImage = UIImage(named: "cat.jpg")
        
        let myImageView:UIImageView = UIImageView()
        myImageView.contentMode = UIView.ContentMode.scaleAspectFit
        myImageView.frame.size.width = 200
        myImageView.frame.size.height = 200
        myImageView.center = self.view.center
        
        myImageView.image = catImage
            
        // Make Image Corners Rounded
        myImageView.layer.cornerRadius = 100
        myImageView.clipsToBounds = true
        myImageView.layer.borderWidth = 10
        myImageView.layer.borderColor = UIColor.lightGray.cgColor
 
        view.addSubview(myImageView)
 
        self.view = view
    }

}

PlaygroundPage.current.liveView = MyViewController()

And here how it looks when I actually run it.
