An app concept shows how the iPod click wheel and cover flow UI would look like on the iPhone's touch screen. Developed in Swift, the app is a proof-of-concept by designer/developer Elvin Hu, who showed his creation in a video on Twitter.

Elvin Hu used SwiftUI to turn the classic iPod user interface into a music playing app. The click wheel works by swiping a finger over it to rotate the cover flow interface. The cover flow interface shows a list of different music albums. In case you are a fan of the cover flow, Apple used to have it on iPhone as a part of the music app, but removed it in iOS 7. Users could use it even in landscape mode, and tap on an album to flip it around and see a list of tracks in it.
