I have already read:
Programatically switching tabs using selectedViewController property
I am using XCode 10 and Swift 4.2
I run 2 lines of code in a ViewController.ViewDidAppear which is assigned to the second Tab Bar Item (index 1). Below myAppsTabBarController is a swift class that subclasses UITabBarController and has a static variable called myTabBarController that is assigned to self.
myAppsTabBarController.myTabBarController?.selectedIndex = 3
myAppsTabBarController.myTabBarController?.selectedViewController = myAppsTabBarController.myTabBarController?.viewControllers[3]
The first line works as I can see the 4th tab bar item light up (like it is selected.) The second line doesn't seem to work as the view doesn't update to the 4th tab. I have printed out myAppsTabBarController.myTabBarController?.viewControllers?.count and it is 4 so I know it exists. Any idea why the second line isn't changing the user's view? Thank you.

Did you call it in the main thread?

For me, both lines are working fine individually. Even, changing the view controller also updates the selectedIndex property accordingly and vice versa.

Can you please share the code for how the viewControllers are setup?

Hmm I'm not sure what you mean by main thread. When my app starts up the 0 index tab bar item is the view that is presented. When the user clicks on the tab bar item at index 1 if certain user data isn't set up (which i check for at the end of ViewDidLoad) then I'd like to send the user to tab bar item at index 3. So this code sits in a function called at the end of ViewDidLoad.

I will add that the second line does seem to encompass the function of the first line so I guess I could drop the .selectedIndex = 3 line.
