Hello! I'm studying swift in college now, and have encountered a problem previewing my code using canvas. Here's part of the code: struct ContentView: View { ......(omitted) var body: some View{ ScrollView{ cards Spacer() cardsAdjuster } } The canvas panel looks all right with the line "ScrollView", as the image shows, with the only problem that "cardsAdjuster" moves with the cards. But if I remove the line "ScrollView", the panel went wrong: As the image displays, all parts of body are displayed separately, and I can't find any setting options to merge them. (Take a look at the top of the screenshot) The problem is also found on my classmate's Xcode 12 running on macOS Monterey. Looking forward to your reply and thoughts. Thank you all!!
