Answer 1

First you need to set equal width and height for getting Circular ImageView.Below I set width and height as 100,100.If you want to set equal width and height according to your required size,set here.

 var imageCircle = UIImageView(frame: CGRectMake(0, 0, 100, 100))

Then you need to set height/2 for corner radius

 imageCircle.layer.cornerRadius = imageCircle.frame.size.height/2
 imageCircle.layer.borderWidth = 1
 imageCircle.layer.borderColor = UIColor.blueColor().CGColor
 imageCircle.clipsToBounds = true
 self.view.addSubview(imageCircle)

Answer 2

struct CircleImage: View {
    var image: Image

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

This is correct for SwiftUI

Don't know if this helps anyone but I was struggling with this problem for awhile, none of the answers online helped me. For me the problem was I had different heights and widths set on the image in storyboard. I tried every solution on stack and it turns out it was something as simple as that. Once I set them both to 200 my circle profile image was perfect. This was code then in my VC.

profileImage2.layer.cornerRadius = profileImage2.frame.size.width/2
    profileImage2.clipsToBounds = true

You can simple create extension:

import UIKit

extension UIImageView {

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

and use it as below:

imageView.setRounded()

All the answers above couldn't solve the problem in my case. My ImageView was placed in a customized UITableViewCell. Therefore I had also call the layoutIfNeeded() method from here. Example:

 class NameTableViewCell:UITableViewCell,UITextFieldDelegate { ...

 override func awakeFromNib() {

    self.layoutIfNeeded()
    profileImageView.layoutIfNeeded()

    profileImageView.isUserInteractionEnabled = true
    let square = profileImageView.frame.size.width < profileImageView.frame.height ? CGSize(width: profileImageView.frame.size.width, height: profileImageView.frame.size.width) : CGSize(width: profileImageView.frame.size.height, height:  profileImageView.frame.size.height)
    profileImageView.addGestureRecognizer(tapGesture)
    profileImageView.layer.cornerRadius = square.width/2
    profileImageView.clipsToBounds = true;
}

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 UIViewControllers viewDidLoad() method. This isn't correct, since it isn't sure what the final frame will be.
