I can't change the text of tab bar controller 8 items (after More button) using Swift

Question

I added a tab bar controller of 8 items, but the system adds the 'more' button for me. The problem is I can't change the title of tab bar item 5 and 'more'. Here is the error message. I have confirmed that I have 8 Items.

Code :

tabBarController?.tabBar.items![5].title = "ok"

Error

Consider the following code:

class TabBarController: UITabBarController {

    override func viewDidLoad() {
        super.viewDidLoad()
        configureViewControllers()
    }

    private func configureViewControllers() {
        let colors: [UIColor] = [.systemRed, .systemBlue, .systemGray, .systemTeal, .systemPink]
        var vcs = [UIViewController]()
        for i in 0...6 {
            let vc = UIViewController()
            vc.view.backgroundColor = colors.randomElement()!
            vc.tabBarItem.title = "VC \(i)"
            vcs.append(vc)
        }
        viewControllers = vcs
    }
}

So you have to set the titles of the view controllers via vc.tabBarItem.title = "your title" or you can set them even inside of your view controllers viewDidLoad() with tabBarItem.title = "...". For further reading: https://developer.apple.com/documentation/uikit/uitabbarcontroller
