I went through the 3rd edition already, and happy to see the arrival of the 4th. Is there a list of changes/additions? I’m trying to avoid going through the whole book again. Thanks. ---

I am responsible for the Mac section - Chapters 21 & 22. There are a few cases where I have added more modern Swift, but mainly it’s just updated to handle Monterey & Xcode 13. ---
