How and where is SwiftUI used?

Cases when SwiftUI does not work

1. Compatibility with Older iOS Versions: SwiftUI was introduced by Apple in iOS 13, which means apps built with SwiftUI will not be compatible with devices running on older iOS versions. If your target audience includes users with older devices that cannot be upgraded to iOS 13 or later, you will need to consider using the traditional UIKit framework instead.
2. Complex UI Customizations: While SwiftUI provides a wide range of UI components and modifiers, there might be cases where you require highly custom UI elements or complex animations that are not yet fully supported by SwiftUI. In such scenarios, you may need to rely on UIKit or other custom solutions to achieve your desired result.
3. Limited Third-Party Library Support: SwiftUI is a relatively new framework, and as a result, the availability of third-party libraries and frameworks specifically designed for SwiftUI is still limited compared to UIKit. If your project heavily relies on existing UIKit-based libraries, you might face challenges integrating them seamlessly into a SwiftUI-based app.
4. Debugging Challenges: SwiftUI’s declarative nature can make it challenging to debug certain issues. When encountering a bug or unexpected behavior in SwiftUI, the error messages and stack traces provided by Xcode may not always be as informative or detailed as when working with UIKit. This can make the debugging process more time-consuming and potentially frustrating for developers.
5. Learning Curve: While SwiftUI aims to simplify the development process, there is still a learning curve involved, especially for developers who are more familiar with UIKit. Transitioning from UIKit to SwiftUI may require investing time and effort in learning the new concepts and paradigms introduced by SwiftUI, which could impact the initial development timeline of a project.
