Customising the UITabBar.appearance in each View Controller [Swift]

Question

I'm trying to set the tab bar to have a different background image on each view controller.

class CharacterVC: UIViewController {

var tabBarApparence = UITabBar.appearance()

override func viewDidLoad() {
    super.viewDidLoad()

    tabBarApparence.backgroundImage = UIImage(named: "BlueTB") //Loaded from Image Asset
}

This works fine and changes it to blue in that view, however when I go to the next view it stays the blue colour and doesn't change to the red colour which I programmed in with this code:

class AnonVC: UIViewController {

var tabBarApparence = UITabBar.appearance()

override func viewDidLoad() {
    super.viewDidLoad()
    tabBarApparence.backgroundImage = UIImage(named: "RedTabBar")
    // addtional code here
}

I have an additional 2 view controllers, one should display the green version of the image and the other the purple version of the image.

Any suggestions which could fix this?

If you want to change appearance of TabBar in a view controller is very easy. You can this in function viewDidLoad or viewWillAppear. The code is the next:

// Set color of titles and icons in tabBar
self.tabBarController?.tabBar.tintColor = UIColor.redColor()
// Set color of background tabBar
self.tabBarController?.tabBar.barTintColor = UIColor.blueColor()
