Answer 1

// code to make the image round


import UIKit

extension UIImageView {
public func maskCircle(anyImage: UIImage) {


    self.contentMode = UIViewContentMode.ScaleAspectFill
    self.layer.cornerRadius = self.frame.height / 2
    self.layer.masksToBounds = false
    self.clipsToBounds = true




    // make square(* must to make circle),
    // resize(reduce the kilobyte) and
    // fix rotation.
    //        self.image = prepareImage(anyImage)
}
}

// to call the function from the view controller

self.imgCircleSmallImage.maskCircle(imgCircleSmallImage.image!)
