What is SwiftUI and what are its advantages?

SwiftUI is a declarative UI framework for all Apple platforms (iOS, macOS, watchOS, tvOS). It allows creating user interfaces using pure Swift.

Advantages:

• Declarative syntax: Instead of describing how to change the UI, we describe what it should display. This makes the code more readable and predictable.
• Cross-platform: The same SwiftUI code can run on all Apple platforms with minor adaptations.
• Live preview: Xcode provides an interactive real-time UI preview, speeding up the development process.
• Automatic support for themes, localization, and accessibility: SwiftUI simplifies the integration of these important aspects.
• Integration with Combine: SwiftUI integrates well with the Combine framework for managing data streams, simplifying reactive programming.

Example of declarative syntax:

// Creating a simple text view
Text("Hello, SwiftUI!")
    .font(.largeTitle) // Applying font modifier
    .padding() // Applying padding modifier
