I have created a simple scene in reality composer (composer not composer pro). It contains just a cube and text item. I convert this to usdz file and load it into a Arkit swift app. Since ios 18/xcode 16 - the "text" element is not displayed at all. The cube is displayed, anchors correctly and can be moved etc....
