How to: Save order of tabs when customizing tabs in UITabBarController

Question

I am having problems finding any other information than the docs for how to save the tab order for my UITabBarController, so that the user\'s customization is saved for next

Answer 1

I'd like to share the code I have been working on for nearly 3 days now trying all sorts of combinations with many errors and failure - the general life of coding! ha ha. Anyway the code below works with Swift 5. It's the extraction of How to: Save order of tabs when customizing tabs in UITabBarController , Sam's Code, but with the for loop update for Swift 5. I have got this working great, all in the TabBarViewController.swift file.

So if you just paste this into your Swift file, make sure your Tab Bar Items have a tag number from the Attributes Inspector and your good to go!

Thanks again to Sam for the Code in the first place.

import UIKit


class TabBarController: UITabBarController, UITabBarControllerDelegate {

let tabOrderKey = "customTabBarOrder"

override func viewDidLoad() {
super.viewDidLoad()

self.delegate = self
loadCustomTabOrder()
}

func loadCustomTabOrder() {

let defaults = UserDefaults.standard
let standardOrderChanged = defaults.bool(forKey: tabOrderKey)

if standardOrderChanged {
    print("Standard Order has changed")

    var VCArray = [UIViewController]()
    var tagNumber = 0

    let tabBar = self as UITabBarController

    if let countVC = tabBar.viewControllers?.count {
        print("\(countVC) VCs in total")
        for x in 0..
