SwiftUI iOS 16 Crash Course - Emoji Quote App in SwiftUI - ShareImageView - Part 5 - Share Image Using ShareLink

The video tutorial covers the implementation of state variables in a SwiftUI project, focusing on creating and managing state variables like 'show sheet' and 'image to render'. It addresses handling missing arguments and toggling views, followed by implementing bindings and adding a share sheet. The tutorial concludes with updating the 'quote of the day' feature and making final adjustments to ensure the app functions correctly.

What is the purpose of the 'show sheet' state variable in the main emoji quote view?

• To manage the visibility of the share sheet
