layer.cornerRadius not working in conjunction with NSLayoutConstraints (swift 3)
profileImageView.frame.width is zero, because of it's frame isn't calculated yet. Inside your profileImageView override layoutSubviews method:
override func layoutSubviews() { super.layoutSubviews() layer.cornerRadius = bounds.width / 2.0}Or if you're using view controller, override viewDidLayoutSubviews method:
override func viewDidLayoutSubviews() { super.viewDidLayoutSubviews() profileImageView.layer.cornerRadius = profileImageView.bounds.width / 2.0}
profileImageView hasn't been laid out yet and doesn't have a size. Presuming this is in a UIViewController subclass, you can put the corner radius code inside viewDidLayoutSubviews:
override func viewDidLayoutSubviews() { profileImageView.layer.cornerRadius = (profileImageView.frame.width / 2)}
