iOS TableViews and Rounded Images (contact photos/ avatars)

Hey all. I just completed the iOS intermediate course for tableviews. I found a way to make the contact photos round within the tableview and thought I would share so you could give it a try. It looks great! Just add this extension in your project. Since it is public, you can access this method in other files/ classes/ TableView Controllers. I used it to make all the contact photos rounded in the master view, and then the profile photo as well in the detail view. 

// Making the image Views Circular. 
public extension UIImage {
    var circle: UIImage {
        let square = size.width < size.height ? CGSize(width: size.width, height: size.width) : CGSize(width: size.height, height: size.height)
        let imageView = UIImageView(frame: CGRect(origin: CGPoint(x: 0, y: 0), size: square))
        imageView.contentMode = UIView.ContentMode.scaleAspectFill
        imageView.image = self
        imageView.layer.borderWidth = 3.0
        imageView.layer.borderColor = UIColor.black.cgColor
        imageView.layer.cornerRadius = square.width / 2
        imageView.layer.masksToBounds = true
        UIGraphicsBeginImageContext(imageView.bounds.size)
        imageView.layer.render(in: UIGraphicsGetCurrentContext()!)
        let result = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return result!
    }
}

Once you have this in, you can call it on an instance of UIImage that you'd like to display within a UIImageView: 

contactImageView.image = contact.image?.circle
