To dynamically change the window size based on the content in visionOS using SwiftUI, you can use the window resizability modifier. This allows the window to resize to match the size of its content. Here's a brief overview of how you can achieve this:
-
Window Resizability Modifier: Apply the window resizability modifier to your window group. This will ensure that the window resizes according to the content size. For example, if you have a movie window group, you can set the window resizability to match the content size, allowing it to resize within specified minimum and maximum limits.
-
Content Size Constraints: Define minimum and maximum sizes for your content. This ensures that the window can resize down to a certain size and up to a reasonable limit, maintaining a good user experience.
-
Initial Size and Placement: Use the default window placement API to specify an initial size for your window. This can be adjusted based on the screen size or other windows.
For more detailed guidance, you can refer to the session Work with windows in SwiftUI at the "Sizing" chapter.
