This is the correct answer. To be clear: (1) Yes there is a mistake in the tutorial. (2) This fix needs to be applied to LandmarkList.swift. On line 15, change "landmarks.filter { landmark in" into "modelData.landmarks.filter { landmark in" (3) Thank you to @ayee999

Back again, after double checking the tutorial. And I realized that the tutorial is actually correct, it DOES mention the same change: "Step 2 Use modelData.landmarks as the data when filtering landmarks." - I guess the problem is that step 2 was somehow easy to miss (or they fixed it since I looked there last time 🤪 ) tutorial at https://developer.apple.com/tutorials/swiftui/handling-user-input and we are talking about Section 5, Step 2.

Can you please detail or point to the detail of the full steps to do a macOS ventura installation on a separate partition? And what is CCC?

Actually I just tested the latest iOS 16.1 beta 4 and it seems like the issue might have been fixed as I once again get images. Thanks 😊
