iPadOS 15 Allows You to Build iPhone and iPad Apps on an iPad
In iPadOS 15, Swift Playgrounds features the ability to create iPhone and iPad apps using Swift UI. Swift Playgrounds app project packages can also be opened and edited in Xcode on a Mac, giving users the option to develop apps across the iPad and Mac.
Code is immediately reflected in the live preview when building apps, and users can run their apps full screen to test them out. Created apps can be submitted to the App Store directly in Swift Playgrounds.
