In Swift How to change the selected tab bar

Question

I am new to swift programming and I have a Tabbed application with 2 UITabBar items , I want that when user taping the second tab, application set the selected tab index to 0 and move user to the first tab. I tried this code in my SecondViewController.swift's viewDidLoad :

self.tabBarController?.selectedIndex = 0

but it doesn't work.

What doesn't work? What error are you getting? – JAL Jun 18 '15 at 16:09 — JAL, Jun 18 '15 at 16:09

This works:

override func viewDidAppear() {
    self.tabBarController?.selectedIndex = 0
}

See this answer for a good explanation of viewDidLoad() vs. viewDidAppear.

Relevant excerpt:

This is where you want to perform any layout actions or do any drawing in the UI - for example, presenting a modal view controller
