Is UIKit is dead? Should we use this in our future projects?
Is UIkit dead?
No, UIKit is not dead. Apple has the following video from the most recent WWDC about UIKit
The choice to use UIKit or SwiftUI for a new project depends on the project and you. Use UIKit if you are comfortable with it or if you need to support iOS 13 and earlier versions of iOS. Use SwiftUI if you are interested in learning it or if you want to make an app that runs on iOS and Mac.
