SwiftUI

SwiftUI is a development framework for building user interfaces for iOS, iPadOS, watchOS, tvOS and macOS, from Apple Inc. SwiftUI provides views, controls, and layout structures for declaring the app's user interface. The framework provides event handlers for delivering taps, gestures, and other types of input, and tools to manage the flow of data from the app's models down to the views and controls that users see and interact with.[1]

SwiftUI was first introduced in 2019 at Apple's WWDC event and has gained significant popularity among developers due to its simplicity, flexibility, and seamless integration with Apple's Swift programming language.

Since SwiftUI is built on a declarative syntax, developers can describe the desired UI and its behavior using a series of structured statements rather than imperatively defining each individual UI element.

One of the most important features of SwiftUI is the ability to provide a real-time preview of the UI while coding. Developers can see the changes they make in the code reflected in the preview, facilitating rapid prototyping and iterative design. SwiftUI also includes a powerful data binding mechanism, enabling automatic synchronization between the UI and the underlying data models. When the data changes, the UI updates automatically, reducing the need for manual updating and synchronization.
