Has anybody had luck with the Project 18 challenges?

I've been trying several things, but I'll limit this post to one specific issue:

Challenge 2 starts with this code from Project 5, and challenges us to offset the words lower down in the list by using GeometryReader.

VStack {
     TextField("Enter your word", text: $newWord, onCommit: addNewWord)
             .textFieldStyle(RoundedBorderTextFieldStyle())
             .autocapitalization(.none)
             .padding()

     List(usedWords, id: \.self) {
             Image(systemName: "\($0.count).circle")
             Text($0)
     }
}

I've been able to offset the Text view based on its position in the List with the code below.

My issues are:

(1) how to access the value of each string from the usedWords array when creating the Text in the List? I can no longer simply use $0 to read the value once the Text is in a GeometryReader. Is there a way to enumerate the List so I can get the appropriate value for each word in the list?

(2) what's a good way to apply the offset only to words that are later in the list? If I have an enumerated list I could apply the offset only after a certain number of words. I've hacked it together here based on the word's position within the bounds of the entire screen.

VStack {
    TextField("Enter your word", text: $newWord, onCommit: addNewWord)
        .textFieldStyle(RoundedBorderTextFieldStyle())
        .autocapitalization(.none)
        .padding()

    GeometryReader { geo in
        List(usedWords, id: \.self) {
            Image(systemName: "\($0.count).circle")
            GeometryReader { textGeo in
                Text(usedWords[0])     //this is very wrong, we don't want to repeat just the first word for each item in the List
                    .offset(x: textGeo.frame(in: .global).midY > UIScreen.main.bounds.size.height * 0.7 ? (textGeo.frame(in: .global).midY/geo.size.height) * 20 : 0)
            }
        }
    }
}

Thanks in advance for any help!
