What is the purpose of SwiftUI?

Let’s begin by creating a framework in Xcode by selecting File > New > Project … from the menu bar. Continue by selecting Framework project template under the iOS tab. Then click Next. Finally name your framework, you can name it whatever you want.

So “SwiftUI” is the thing that draws buttons and stuff, Swift is the language it is written in , and probably the language that a programmer doing a “let’s show a list of flowers, let people tap on them, and see details about them” app uses.

SwiftUI helps you build great-looking apps across all Apple platforms with the power of Swift — and as little code as possible . With SwiftUI, you can bring even better experiences to all users, on any Apple device, using just one set of tools and APIs.

MVVM is the new standard architecture SwiftUI comes with MVVM built-in. In the simplest case, where the View does not rely on any external state, its local @State variables take the role of the ViewModel , providing the subscription mechanism ( Binding ) for refreshing the UI whenever the state changes.

Xcode also includes Apple’s WebObjects tools and frameworks for building Java web applications and web services (formerly sold as a separate product). As of Xcode 3.0, Apple dropped WebObjects development inside Xcode; WOLips should be used instead. Xcode 3 still includes the WebObjects frameworks.

Overview. The UIKit framework provides the core objects that you need to build apps for iOS and tvOS . You use these objects to display your content onscreen, to interact with that content, and to manage interactions with the system.
