Answer 1

For swift 3.2 and 4

extension UIImageView{
    func changePngColorTo(color: UIColor){
        guard let image =  self.image else {return}
        self.image = image.withRenderingMode(.alwaysTemplate)
        self.tintColor = color
    }
}

Use :

self.yourImageView.changePngColorTo(color: .red)
