When a member is clicked, the app proceeds to the detail view displaying their picture along with a short bio about them. In this tutorial, we’ll look at the basics of SwiftUI and explore how to create navigation views, images, texts, and lists by building a simple contact list that shows all our tutorial team members. It’s important that developers learn early how to use SwiftUI because Apple will eventually migrate much of their focus to this framework. If you want to dive deeper into SwiftUI, you can check out our Mastering SwiftUI book. So now, your UI code can be synchronized across all platforms giving you more time to focus on the minor platform-specific code.Įditor’s note: This tutorial has been updated for Xcode 11.4 and Swift 5.2.

What’s even more is that the use of SwiftUI automatically enables your app to take advantage of features like Dynamic Type, Dark Mode, Localization, and Accessibility. Since SwiftUI is built with Swift, it allows you to create the same complexity of apps with much less code. However, the syntax is very easy to understand and can quickly be previewed with Automatic Preview. Unlike UIKit which was commonly used conjoined with storyboards, SwiftUI is completely based on code.
SwiftUI is a brand new framework that allows you to design and developer user interfaces with way less code and in a declarative way.
