A little extension to UIImageView which makes a nice circular profile pic

SwiftProfileImage.swift

extension UIImageView {
    func resizeForProfilePic(){
        self.layer.borderWidth = 1
        self.layer.masksToBounds = false
        self.layer.borderColor = UIColor.blackColor().CGColor
        self.layer.cornerRadius = self.frame.height/2
        self.clipsToBounds = true
    }
}
