Xcode 11: User Interface Menu for New Projects

When you create an iOS or Cocoa app project in Xcode 11, there is a User Interface menu in Step 2 of the New Project Assistant.

For iOS projects the user interface choices are SwiftUI and storyboard. For Mac projects the user interface choices are SwiftUI, storyboard and xib file.

Xcode defaults to using SwiftUI as the user interface for new Xcode 11 projects. If you want to use storyboards and view controllers for your app’s user interface, make sure you choose Storyboard from the User Interface menu.
