in your viewDidload add this line of code

self.headerImageView.layer.cornerRadius = self.headerImageView.frame.size.width / 2

In Swift 4 you can do it fairly easily like this:

yourUIImage.layer.cornerRadius = 10 // Set it how you prefer
yourUIImage.layer.masksToBounds = true

And if you use a rather long rectangle image, for example for a featured content part in your app or whatever, make sure the Content Mode is set to Scale To Fit because otherwise the corners will be somehow rounded but will cut badly and it will not be a perfect round corner but rather a rounded, then sharp cut where it clips.

For rounded circle image frame in swift, what it worked for me was:

self.profileImageView.image =  UIImage(named:"profileUser")
self.profileImageView.layer.cornerRadius = self.profileImageView.frame.size.width / 2
self.profileImageView.clipsToBounds = true

And for adding a shadow:

self.profileImageView.layer.masksToBounds = NO;
self.profileImageView.layer.cornerRadius = 8;
self.profileImageView.shadowOffset = CGSizeMake(5.0, 5.0);
self.profileImageView.shadowRadius = 5;
self.profileImageView.shadowOpacity = 0.5;

Swift 5.0:

My personal preference is to have an extra swift file for specific changes like this one. What I do is then create a class e.g. "RoundCorner" which is a subclass of the element I want to change in this case a View element. And then I am overriding the individual settings.

class RoundCorner: UIView {
override func draw(_ rect: CGRect) {
    self.layer.cornerRadius = 10 // change this number to get the corners you want
    self.layer.masksToBounds = true
    }
}

After that, you only have to select the element you want this changes on, and set the custom class to the class we created earlier.

Setting layer.cornerRadius = 10 at User Defined Runtime Attributes section on the Identity inspector works even on repeatable elements like table cells.

If you want to use the storyboard. I applied this and make sure that "Clip to bounds" is enable.

If you want to have an option to round each UIImageView, you can copy this code into your project without forgetting to check clip to bounds and set its value to true

import UIKit

@IBDesignable
extension UIImageView
{
    private struct AssociatedKey
    {
        static var rounded = "UIImageView.rounded"
    }

    @IBInspectable var rounded: Bool
    {
        get
        {
            if let rounded = objc_getAssociatedObject(self, &AssociatedKey.rounded) as? Bool
            {
                return rounded
            }
            else
            {
                return false
            }
        }
        set
        {
            objc_setAssociatedObject(self, &AssociatedKey.rounded, newValue, .OBJC_ASSOCIATION_RETAIN_NONATOMIC)
            layer.cornerRadius = CGFloat(newValue ? 1.0 : 0.0)*min(bounds.width, bounds.height)/2
        }
    }
}

I was tired of writing set radius and mask to bound for each UIView. So I made the following extenstion for UIView. Should work for every UIView subclass, though I have not tested it. The extension can be narrowed down for specific Views you use of course.

extension UIView {      
    func setRadius(radius: CGFloat? = nil) {
        self.layer.cornerRadius = radius ?? self.frame.width / 2;
        self.layer.masksToBounds = true;
    }
}

It will default to the view's half width if you don't pass it any specific value.

Try this, it worked for me.

self.profileImageView.layer.cornerRadius = self.profileImageView.frame.size.width / 2
self.profileImageView.clipsToBounds = true

let imageView = UIImageView(frame: CGRectMake(0, 0, 100, 100))
imageView.backgroundColor = UIColor.redColor()
imageView.layer.cornerRadius = 8.0
imageView.clipsToBounds = true

Result:
