Unable to set progress bar progress twice in iOS?

Question

I have UIProgressView.On begin to text edit for a UITextField I set the value of progress bar to 1 . Before that initially I make it progress to 0.1 .But it is setting progress only once. If I first set progress to 0.1 then after it does not set progress to 1.please tell me what is the issue ?

func textFieldDidBeginEditing(_ textField: UITextField) {
    setViewBottomColor()

    var view:BottomView?

    if textField == textFieldEmail {
        view = self.bottomViewFirst
        view?.trackTintColor = Constant.AppColor.viewBottom
        view?.progressTintColor = Constant.AppColor.purpleViewColor

    }
    else if textField == textFieldPassword {
        view = self.bottomViewSecond
        view?.trackTintColor = Constant.AppColor.viewBottom
        view?.progressTintColor = Constant.AppColor.purpleViewColor
    }
    if view != nil {
        view?.setProgress(1, animated: true)
        UIView.animate(withDuration: 1.0, animations: {
            view?.layoutIfNeeded()
        }, completion: { (finish) in
        })
}
}

func setViewBottomColor() {

    self.bottomViewFirst.trackTintColor = Constant.AppColor.viewBottom
    self.bottomViewFirst.progressTintColor = Constant.AppColor.purpleViewColor
    self.bottomViewFirst?.setProgress(0.1, animated: false)
    self.bottomViewFirst?.layoutIfNeeded()

}

Check below code snippet I have used to check. It is working fine.

You may check few things:

1. All IBOutlets connections must be there.
2. If you are using custom UIProgressView as BottomView then you must changed both progress view class in xib/storyboard as well.

3. No Need to have view animation if for progress value change only.

    func textFieldDidBeginEditing(_ textField: UITextField) {
   
       resetProgresses()
       var view = UIProgressView()
   
       if textField == t1 {
           view = self.progressBar
           view.trackTintColor = .red
           view.progressTintColor = .green
   
       }
       else if textField == t2 {
           view = self.progressBar2
           view.trackTintColor = .green //Constant.AppColor.viewBottom
           view.progressTintColor = .red//Constant.AppColor.purpleViewColor
       }
   
       if view != nil {
           view.setProgress(1, animated: true)
       }
   
     }
   
    func resetProgresses()  {
       self.progressBar?.setProgress(0.1, animated: true)
       self.progressBar2?.setProgress(0.1, animated: true)
   
     }
