Conclusion

In this lesson, you learned about building complex views in SwiftUI. First, you learned how to use a ViewBuilder to pass views into another view when doing iterations. You also saw how generics let your views work without hard coding specific types. Finally, you saw how using a KeyPath provides a way to reference an object property without invoking the property.

Now, you can:

• Leverage SwiftUI’s principle of modular design to build a complex view from smaller, simpler ones.
• Use ViewBuilder to create a reusable view.
• Use generics and key paths to encapsulate a view for reuse anywhere.

For more on key paths, see the Key-Path Expression section of the Swift Programming Language Manual’s Expressions chapter. For more about generics in Swift, see Swift Generics Tutorial: Getting Started.
