[android] Displaying a message in iOS which has the same functionality as Toast in Android

This is how I have done in Swift 3.0. I created UIView extension and calling the self.view.showToast(message: "Message Here", duration: 3.0) and self.view.hideToast()

extension UIView{
var showToastTag :Int {return 999}

//Generic Show toast
func showToast(message : String, duration:TimeInterval) {

    let toastLabel = UILabel(frame: CGRect(x:0, y:0, width: (self.frame.size.width)-60, height:64))

    toastLabel.backgroundColor = UIColor.gray
    toastLabel.textColor = UIColor.black
    toastLabel.numberOfLines = 0
    toastLabel.layer.borderColor = UIColor.lightGray.cgColor
    toastLabel.layer.borderWidth = 1.0
    toastLabel.textAlignment = .center;
    toastLabel.font = UIFont(name: "HelveticaNeue", size: 17.0)
    toastLabel.text = message
    toastLabel.center = self.center
    toastLabel.isEnabled = true
    toastLabel.alpha = 0.99
    toastLabel.tag = showToastTag
    toastLabel.layer.cornerRadius = 10;
    toastLabel.clipsToBounds  =  true
    self.addSubview(toastLabel)

    UIView.animate(withDuration: duration, delay: 0.1, options: .curveEaseOut, animations: {
        toastLabel.alpha = 0.95
    }, completion: {(isCompleted) in
        toastLabel.removeFromSuperview()
    })
}

//Generic Hide toast
func hideToast(){
    if let view = self.viewWithTag(self.showToastTag){
        view.removeFromSuperview()
    }
  }
}
