To set the draw order for SwiftUI views in visionOS, you can utilize SwiftUI's declarative syntax and its composition capabilities. SwiftUI allows you to define the hierarchy and order of views through its container views like HStack, VStack, and ZStack. The ZStack is particularly useful for managing the draw order, as it layers its child views on top of each other, with the first view in the stack being drawn at the bottom and the last view on top.
For more advanced control, you can use SwiftUI's low-level APIs to create custom layouts and apply custom shaders, as mentioned in the SwiftUI essentials session. This session discusses how to use these tools to create unique experiences, such as using animations and graphics tricks to enhance your app's interface.
If you are interested in learning more about how SwiftUI handles view composition and modifiers, the Demystify SwiftUI containers session provides insights into how declared subviews are resolved into the views that appear on screen, which can help you understand how to manage the draw order effectively.
