What is SwiftUI?

SwiftUI is Apple's declarative user interface framework designed to build apps across all of Apple's platforms. It is easy to learn and packed with advanced features, making it the best way to build apps for any Apple device. SwiftUI allows developers to focus on describing the UI they want, while it handles details like dark mode, dynamic type, and tracking changes in the model. This approach enables code sharing across multiple devices and platforms.

SwiftUI integrates seamlessly with the underlying OS and other frameworks like UIKit and AppKit, providing interoperability and allowing incremental adoption. It supports a wide range of features, enabling apps to take full advantage of the devices they run on and feel native to Apple's platforms. SwiftUI also offers tools for creating custom experiences, such as custom control styles, high-performance imperative drawing with canvas, and custom layouts.
