When building a SwiftUI app, there are several best practices to keep in mind:

  1. Declarative Syntax: SwiftUI uses a declarative syntax, which means you describe what you want the UI to look like and SwiftUI takes care of the details. This approach allows you to focus on the design and functionality of your app without worrying about the underlying implementation details.

  2. Incremental Adoption: You don't need to rewrite your entire app in SwiftUI to take advantage of its features. You can incrementally adopt SwiftUI in your existing app, integrating it with UIKit or AppKit as needed. This flexibility allows you to modernize your app at your own pace (SwiftUI essentials).

  3. Adaptive Views: SwiftUI automatically provides adaptivity along several dimensions, such as dark mode, dynamic type, and localization. Use Xcode previews to quickly see how your views look in different contexts without needing to run the app repeatedly (SwiftUI essentials).

  4. Customizability: SwiftUI offers a large set of modifiers and protocols to customize and fine-tune the look and feel of your app. You can build unique custom experiences using low-level APIs, such as custom control styles, canvas for high-performance drawing, and even custom Metal shaders (SwiftUI essentials).

  5. Cross-Platform Code Sharing: SwiftUI enables you to share more of your code across different Apple platforms. Once you have a user interface built using SwiftUI for one platform, you have an excellent start to bringing that UI to any other Apple platform (SwiftUI essentials).

  6. Integration with Other Frameworks: SwiftUI integrates seamlessly with other frameworks in the SDK, such as Swift Data for persistent models and Swift Charts for creating information visualizations. This integration helps you build comprehensive and feature-rich apps (SwiftUI essentials).

  7. Use of Previews: Xcode Previews is a powerful tool that allows you to see your SwiftUI views in real-time as you code. This feature helps you understand how your UI will look and behave without needing to run the app on a device (Platforms State of the Union).
