In addition, SwiftUI and UIKit are interoperable, so choosing one technology doesn’t preclude you from using the other in the same app. Both SwiftUI and UIKit provide everything you need to write apps, but SwiftUI offers a better starting point for development. If you’re unsure where to start, choose SwiftUI as your app-builder technology. For a walkthrough of using UIKit to build apps, view the Getting Started with Today tutorial. Write the code you need to update views and controls, change their configuration, and communicate changes to other parts of your app. UIKit offers a more traditional approach to building apps, giving you full control over the management of interface elements. UIKit lets you build your interface programmatically in your code or visually using storyboards. Swift code also produces software that runs lightning-fast, and it’s interoperable with Objective-C so you can include source files for both languages in the same project. Swift is the preferred option because its syntax is concise, safe by design, and has modern features that make your code more expressive. Adopt SwiftĪs you set up your project, consider which programming language to use.

For additional information about how to use Xcode, view Xcode documentation. For example, select the Game option to draw your app’s content using one of several graphics technologies. The app type also defines the approach for creating your app’s UI. The option you choose determines the initial configuration of your project, including what default code Xcode provides. Xcode gives you several options for your initial app type. To create a new project in Xcode, choose File > New > Project and follow the prompts. Xcode includes the SDKs for iOS, iPadOS, macOS, tvOS, and watchOS.
