Disable tabbar item - Swift

Here is the answer

if  let arrayOfTabBarItems = tabBarViewController.tabBar.items as! AnyObject as? NSArray,tabBarItem = arrayOfTabBarItems[2] as? UITabBarItem {
        tabBarItem.enabled = false
    }

Here's my code for doing the same, using Swift 3:

    let tabBarControllerItems = self.tabBarController?.tabBar.items

    if let tabArray = tabBarControllerItems {
        tabBarItem1 = tabArray[0]
        tabBarItem2 = tabArray[1]

        tabBarItem1.isEnabled = false
        tabBarItem2.isEnabled = false    
    }

Just put the block of code above in the viewDidLoad() method for starters and don't forget to create the tabBarItem variables and you're all good to go from there!

In case someone is looking how to disable all tab bar items:

if let items = tabBarController?.tabBar.items {
        items.forEach { $0.isEnabled = false }
}
