@IBOutlet weak var View_Mor: UIView!
override func viewDidLoad() {
    super.viewDidLoad()
    navigationController?.hidesBarsOnSwipe = true
}
override var prefersStatusBarHidden : Bool {
    if self.navigationController?.isNavigationBarHidden == true {
        return true
    } else {
        return false

What you can do is implement this function.

func scrollViewDidScroll(_ scrollView: UIScrollView) {

    if scrollView.isTracking {   
    // ... perform actions
         //MARK:- Show Status Bar
         UIApplication.shared.isStatusBarHidden = true
    } else {
    //.. not tracking
        //MARK:- Hide Status Bar
        UIApplication.shared.isStatusBarHidden = false
    }
}

you can then detect when the user is dragging the scroll view and perform actions based on what it is you want to do and when.

I hope this helps.

Edit———-

private var hideStatusBar: Bool = false

override var prefersStatusBarHidden: Bool {
    return hideStatusBar
}

override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation {
    return UIStatusBarAnimation.slide
}

Usage 

   func scrollViewDidScroll(_ scrollView: UIScrollView) {

        if scrollView.isTracking {   
        // ... perform actions
             hideStatusBar = true 
        } else {
        //.. not tracking
            hideStatusBar = false 
        }
    }
