Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

// 1. First Create a Dummy UIViewController that has a root relation with the UITabBarController
// 2. Make this controller implement a UITabBarControllerDelegate
// 3. In ViewDidLoad:
  override func viewDidLoad() {
    super.viewDidLoad()
    self.tabBarController?.delegate = self
  }
// 4. Implement this delegate method:
  func tabBarController(tabBarController: UITabBarController, didSelectViewController viewController: UIViewController) {
    let isModalTab = viewController == self
