When to create new storyboard vs View Controller for a new screen?

Question

I am new to iOS development and cannot find an answer for this.

When should I create a new storyboard and when should I just create a new View Controller for a new screen?

Launch Screen and Main are two different storyboards. Let's say Main is login screen, so after user is logged in, he should see a new screen of something. Which method should I use to create that screen?

Answer 1

To directly answer your last question, use the Main storyboard only for this: Create the scene that your user will see when he is logged in. Make that be the first view that is shown. Then create another scene that is your login screen. When your main screen is launched, have it check to see if you're logged in. If not, it should modally launch your login screen.
