At the 2019 WWDC Apple introduced a new UI framework called SwiftUI. From the initial phase of iOS development, we are looking at Xibs and storyboards to build a user interface in ios, macOS and WatchOS app, many more developers were fed-up from developing UI by Storyboard, maybe you are one of them, there are a lot of drawbacks of UIkit over SwiftUI.
