Should I use SwiftUI vs storyboard?

The answer is YES ! Here we will be discussing a simple way to use SwiftUI into our existing project, which already consists of a storyboard.

There is no direct way of migrating from storyboard to swift UI . This compels a developer to continue the use of the storyboard for existing apps and in lower versions. Since, it is very new so there is less community support which is not the case for storyboard.9 Kas 2021

For most new developers coding on iOS 13 or higher, you should learn SwiftUI . If you need to maintain an older code base with Storyboards, you should learn Storyboards.
