To dynamically set the size of a window in visionOS, you can use the window resizability modifier in SwiftUI. This allows the window to resize based on the content it contains. For example, if you have a window that needs to adjust its size according to the content, you can apply this modifier to ensure the window resizes appropriately when the content changes.
Additionally, you can use the default window placement modifier to set the initial position and size of a window programmatically. This can be useful for customizing how and where a window appears when it first opens.
For more detailed guidance, you can refer to the session Work with windows in SwiftUI (09:43) which covers window sizing in visionOS.
