SwiftUI Custom View
Generated on 8/22/2024

To create custom views in SwiftUI, you can conform to the View protocol and define a body property that returns the view you want to represent. This allows you to use the same view-building syntax that SwiftUI provides, enabling compositional features and quick iteration. You can also create additional view properties to keep your code organized and reusable.
For example, you can refactor parts of your view into private view properties, allowing you to reuse the same view with different inputs. This is demonstrated in the SwiftUI essentials session, where a custom view is used to display information about different pets.
Additionally, SwiftUI provides APIs for building custom container views, which can support advanced capabilities like grouping content into sections with configurable headers and footers. This is covered in the Demystify SwiftUI containers session, where you can learn how to use new APIs to build custom container views.
