UI Development Trend in 2020: Declarative UI to Rule Them All

In year 2020 it seems that major players in UI development are agreed in how we, developers, should design the UI (User Interface) of our apps or web apps. In this article I will show you the current UI development trends with different frameworks and environments available in 2020 and sum them up. Later I’ll take a look on the UI development trends in Java / GWT / J2CL.

Design Trend in UI

SwiftUI

SwiftUI has renovated the whole UI development in Apple world. Native on all Apple platforms with all those nice design tools set a very high bar for UI development. Also move from imperative UIKit / AppKit / WatchKit to declarative design to be able to make UI development more easier and straight forward. So how do you implement the UI today? You describe your UI textually. If you need a state you can mark a variable with @State and then use it to write something to it like $name. To read the content we just need to use \(name). This is what we call “two ways binding”. So each time we write something into the TextField the variable name will be updated and the Text which uses that variable will be updated automatically.
