How to hide bar button item

You can hide it by disable the button & change it tintColor like that,

self.navigationItem.rightBarButtonItem?.isEnabled = false
self.navigationItem.rightBarButtonItem?.tintColor = UIColor.clear

do it right or left BarButtonItem whatever you preferred. Hope it helps.

you can hide it like this:

self.navigationItem.leftBarButtonItem = nil

and you can add a new left button like this:

self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "Button", style: .Plain, target: self, action: #selector(ViewController.buttonTapped))

I hope that helps,

Cheers
