SwiftUI is a fantastic framework for building iOS apps, offering a declarative approach to building user interfaces. However, as projects grow, SwiftUI views can become large and difficult to maintain. In this article, we’ll explore strategies for breaking down large SwiftUI views into manageable, reusable components while maintaining readability and scalability.

Why Refactor Large SwiftUI Views?

Large SwiftUI views can lead to several issues:

• Reduced Readability: Code becomes harder to understand and maintain.
• Limited Reusability: Duplicated code may emerge when components aren’t modular.
• Complex State Management: Managing state for large views can be complex.
• Testing Challenges: Extensive views make unit testing difficult.

By applying effective refactoring techniques, you can mitigate these issues and create a more organized and modular codebase.

Signs That Your SwiftUI View Needs Refactoring

Before diving into refactoring, consider whether your SwiftUI view exhibits these signs:

• The view file exceeds 200 lines of code.
