In visionOS, is there a way to temporarily hide the window close/position handle at the bottom of a window? The Safari app does this, so it must be possible.

When tapping the sidebar button, the window expands in the leading edge to accommodate the sidebar, and shrinks when closed. Can this be achieved with public APIs on UISplitView or NavigationSplitView?

Hi Folks, I have two question if you can help me, first is as I tested none of env trackers work in simulator I know Reality kit needs to get data from LIDAR or camera to detect env and depth the question is: the env in xcode env is a just a HDR image? means we can not make any app for VisionPro until we get a device? as I watch Apple videos all are using real device and none of them are in xcode simulation when tracking world. Second question is are we able to add light or remove default light from scene? whatever I did it doesn't have any effect on my scene. I'm 3d model maker too with Blender so I can understand the graphs in composer pro but many of those doesn't reflect any effect. Thank you so much!
