How do I make a UIImageView with rounded corners on a Swift iOS Playground?
Inside it needs to be filled with a color.

Answer 1

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;
