While SwiftUI is excellent there are some issues when dealing with missing components, and often needing to interface with UIKit.
SwiftUIX is a project that aims to fill the gaps providing many missing components with a simple coding style.

There are also some other helpers included such as helpers for color, control flow, and custom views such as for search.
