UIKit ViewController with SwiftUI #If you are curious like me, you must have tested SwiftUI. Personally I like this framework more and more. But I will tell you about my feedback in another article. However I have to reproach it for something: it still lacks a lot of things! And yes, SwiftUI tries to join all the worlds (iOS, macOS, …) in one. The problem is that the task is not easy.

Have you ever made an iOS app with UIKit? Have you ever made your own views? Customized a user control or a view? Then you have probably already been in contact with the frames and bounds.

In software development there is one thing that is difficult to achieve : quality. Anyone can code but few are able to code good software. When I say good I mean robust, stable and malleable according to the necessary evolutions. But to guarantee such a quality you need tools. Beyond the timeless design pattern, debugging tools or other, there are especially unit tests. Of course making an iOS application in Swift is no exception to the rule.
