Question

I try do it in willMove method but get bug when I break gesture(swipe to back VC)

override func willMove(toParent parent: UIViewController?) {
super.willMove(toParent: parent)

self.tabBarController?.tabBar.isHidden = true
}

Give some more information about what you have tried till now? — Ankit Jayaswal, Sep 21 '18 at 06:42
And I won't put this logic to other VC. I need hide and show on current VC. Show when current VC loaded and hide when current VC close. — Aleksandr Maybach, Sep 21 '18 at 06:50
Have you considered making your own tab bar? It's just a `UIView` at the bottom of a container view controller that you would be able to easily toggle using the container view's scroll view delegate. — trndjc, Sep 21 '18 at 07:02

Use below method in ViewDidLoad() of ViewController(where you are going)

self.tabBarController?.tabBar.isHidden = true

and in ViewDidDisappear()

self.tabBarController?.tabBar.isHidden = false

Can I do it in current VC? Don't use both VC? – Aleksandr Maybach Sep 21 '18 at 06:56
You can do it in current VC where you are going(Push/Pop). its mean for a specific view controller tab bar will be hidden and when you are about to leave that controller form stack then tab bar will show. if any issue please let me know – Saurabh pandey Sep 21 '18 at 07:24

In your current view controller:

In viewDidDisappear:

self.tabBarController?.tabBar.isHidden = true

In ViewDidAppear:

self.tabBarController?.tabBar.isHidden = false

in viewDidDisappear self.tabBarController = nil – Aleksandr Maybach Sep 21 '18 at 07:00
In iOS view-controller's are arranged in stack, even if you go to next view-controller previous one stays in your stack. So if you will set `self.tabBarController = nil`, then on coming back it will not be shown again as `nil` will dealloc it from memory. – Ankit Jayaswal Sep 21 '18 at 07:03
sorry I mean its value is nil. (print(self.tabBarController)) – Aleksandr Maybach Sep 21 '18 at 09:58
