iOS 15: Why does \.self work for ForEach? – Core Data SwiftUI Tutorial 1/7

Is the point of this that you can now safely foreach over an array with non-unique elements? Let studentGrades = [92, 88, 100, 98, 92]. Good student.

Thank you very much for explanation !

why doesn't he explain why the hashs are separate in between app runs when before he says the point of hashs is that "hello world" will have the same hash all the time?

One basic understanding I lacked that needed to be spelled out for me:
\.self refers to each element of the ForEach array, not the \.self of the containing ContentView Struct

Why is this Core Data Swift Tutorial 1/7 after the Bookworm project which also uses Core Data?

Interesting.
