How do I decide between SwiftUI and UIKit for my app?

Deciding between SwiftUI and UIKit for your app depends on several factors, including the nature of your project, your familiarity with the frameworks, and the specific requirements of your app. Here are some key points to consider:

SwiftUI

Declarative Syntax: SwiftUI uses a declarative syntax, which allows you to describe the UI and its behavior in a straightforward way. This can make your code more readable and easier to maintain.
Cross-Platform: SwiftUI is designed to work across all Apple platforms (iOS, macOS, watchOS, tvOS, and visionOS). This means you can share more code across different devices.
Modern Features: SwiftUI integrates seamlessly with modern iOS features like dark mode, dynamic type, and accessibility. It also supports advanced features like custom animations and metal shaders (SwiftUI essentials).
Incremental Adoption: You can adopt SwiftUI incrementally in your existing UIKit or AppKit projects. This means you don't have to rewrite your entire app to start using SwiftUI (SwiftUI essentials).
Productivity: SwiftUI can help you move from prototype to production faster, allowing you to focus on what makes your app unique (SwiftUI essentials).

UIKit

Imperative Syntax: UIKit uses an imperative approach, which might be more familiar if you have experience with traditional object-oriented programming.
Mature and Feature-Rich: UIKit has been around for a long time and offers a rich set of features and controls that have been tested and refined over the years.
Interoperability: SwiftUI provides seamless interoperability with UIKit. You can use UIKit views and view controllers within a SwiftUI app and vice versa (SwiftUI essentials).

Recommendations

New Projects: If you are starting a new project, SwiftUI is generally recommended due to its modern approach and cross-platform capabilities (Platforms State of the Union).
Existing Projects: For existing projects, you can incrementally adopt SwiftUI to take advantage of its features without needing to rewrite your entire app (SwiftUI essentials).
