Answer 1

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.
