Xcode7 Swift - iPad App NavigationItem title not showing

问题

I am using the latest XCode 7 Beta and creating a simple iPad application using Swift programming language.

This is how I have setup my Storyboard:

1. I started with a single view app template
2. Then I embedded the view in a NavigationController
3. I then created my "Login" view UI elements
4. I then dropped a TabBarViewController onto the storyboard
5. I then linked the "Login" button to the TabBarController
6. Then within each view of the tabbar, I added a NavigationBarItem and set a title

When the app runs and I click the login button, I am taken to the TabBarController, but I do not see the title.

This is how my storyboard looks like:

The app runs like this (after I clicked the login button):

Any ideas why? Am I using the controls incorrectly? Or is this a bug in Xcode 7 Beta?

This issue exists even in older Xcode versions. I resolved this issue in next steps:

1. Create custom class for Sales and Customers
3. Add self.tabBarController!.title = "Sales or Customers" in viewWillAppear() method for each custom class.

Please set title in view didload:

navigationItem.title = "title"
