// First Step

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    Label.text = ""
    Label.animation(typing: "Bangladesh is small country.", duration: 0.1)
}

extension UILabel {
    func animation(typing value: String, duration: Double){
        for char in value {
            self.text?.append(char)
            RunLoop.current.run(until: Date() + duration)
        }
    }
}



// Second System:


override func viewDidLoad() {
        super.viewDidLoad()
        Label.animate(newText: "Bangladesh is small country", characterDelay: 0.1)
}


extension UILabel {
    func animate(newText: String, characterDelay: TimeInterval) {
        DispatchQueue.main.async {
            self.text = ""
            for (index, character) in newText.enumerated() {
                DispatchQueue.main.asyncAfter(deadline: .now() + characterDelay * Double(index)) {
                    self.text?.append(character)
                    self.fadeTransition(0.2)
                }
            }
        }
    }
}

extension UIView {
    
    func fadeTransition(_ duration:CFTimeInterval) {
        let animation = CATransition()
        animation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
        animation.type = CATransitionType.fade
        animation.duration = duration
        layer.add(animation, forKey: CATransitionType.fade.rawValue)
    }
}
