Reply to NSBundle MetalTools.framework/ principal class is nil because all fallbacks have failed
Bought a brand new Mac. Installed Xcode via App store (2024-12-09) Dec 2024. Followed the official tutorial for SwiftUI here: https://developer.apple.com/tutorials/swiftui/creating-and-combining-views At the bit where it wants to demo live editing of the app, nothing happens (despite various attempts, key combos, going through google advice). On finding the 'debug' app I can see this message displays when I try to do the 'live inspector edit' to change the string. Can't find or decode reasons Failed to get or decode unavailable reasons NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed I don't see the expected 'inspector dialog' the tutorial shows in the screen shot. Nothing happens (apart from this message showing). Could this error be causing the issue of the inspector not showing up like it does in the tutorial? Thanks! PS: I am new to the platform, so sorry if I missed anything obvious.
