ScrollView not working after reload view swift 3

Question

I'd like to reload my View but after I reload it my ScrollView not working, but everything else refresh correctly. Here is my code to refresh view:

extension UIViewController {
    func reloadViewFromNib() {
        let parent = view.superview
        view.removeFromSuperview()
        view = nil
        parent?.addSubview(view) // This line causes the view to be reloaded
    }
}

I tried to put these into my viewDidLoad maybe I just need to refresh the SrollView manually but it's still not working.

self.beSrcollView.bounces = true
self.beSrcollView.delegate = self
self.beSrcollView.updateConstraints()
self.beSrcollView.isScrollEnabled = true
self.beSrcollView.updateFocusIfNeeded()
self.beSrcollView.setNeedsFocusUpdate()
self.beSrcollView.needsUpdateConstraints()

Have you any idea how to fix this?
