⚠️ Compiler Error

This week's theme: SwiftUI View Modifiers!

  1. Much like UIKit, SwiftUI allows the interface orientation to be manipulated using statusBar(orientation:), moving the status bar to one of the four screen edges.
  1. Tooltips can be added to SwiftUI views using the help(_:) modifier, helping to guide the user around the interface without them needing to directly invoke any actions.
  1. Any view in the hierarchy can be modified with onOpenURL(perform:) to perform localized URL handling so long as it is part of the hierarchy when the URL is opened.
  1. A badge can be added to tab bar items using the badge(_:) modifier, but this will also add a visual indicator to list rows to help convey supplementary information.
