Updated Answer for Swift 2.0

`
let tabBarOrderKey = "tabBarOrderKey"

extension TabBarButtonsController: UITabBarControllerDelegate {

 // Saves new tab bar custom order

  func tabBarController(tabBarController: UITabBarController, didEndCustomizingViewControllers viewControllers: [UIViewController], changed: Bool) {
var orderedTagItems = [Int]()
if changed {
  for viewController in viewControllers {
    let tag = viewController.tabBarItem.tag
    orderedTagItems.append(tag)

  }
  NSUserDefaults.standardUserDefaults().setObject(orderedTagItems, forKey: tabBarOrderKey)
}
}

// set up tag to compare with when pulling from defaults and for saving initial tab bar change

func setUpTabBarItemTags() {
var tag = 0
if let viewControllers = viewControllers {
  for view in viewControllers {
    view.tabBarItem.tag = tag
    tag += 1
  }
 }
}

// Get Saved Tab Bar Order from defaults

func getSavedTabBarItemsOrder() {
var newViewControllerOrder = [UIViewController]()
if let initialViewControllers = viewControllers {
  if let tabBarOrder = NSUserDefaults.standardUserDefaults().objectForKey(tabBarOrderKey) as? [Int] {
    for tag in tabBarOrder {
      newViewControllerOrder.append(initialViewControllers[tag])
    }
    setViewControllers(newViewControllerOrder, animated: false)
  }
 }
}

}

Remember to set the delegate and call these methods in the view did load
