I know that you can't use a sheet inside of a ForEach view but my workaround outputs me most of the time the right index but sometimes just the first.

@State private var isEditPresented: Bool = false
@State private var cardIndex: Int = 0

var body: some View {
    ForEach(lesson.cards.indices, id: \.self) { index in
        Button {
            cardIndex = index
            print("edit: \(cardIndex)")
            isEditPresented = true
        } //:BUTTON
    }.sheet(isPresented: $isEditPresented) {
        EditCardView(cardIndex: cardIndex)
    } //:FOREACH
} //:BODY

The print statement outputs: edit: 1

My EditCardView:

@State var cardIndex: Int

var body: some View {
    Form {
        SomeViews()
    }.onAppear() {
        print("editView: \(cardIndex)")
    } //:FORM
} //:BODY

The interesting thing is that the first print statement is edit: 1 but the print statement from my EditCardView returns editView: 0 Sometimes it works fine and prints:

edit: 1
editView: 1

How do I fix that?

Use .sheet(item: ...) instead, or capture the variable, like .sheet(isPresented: $isEditPresented) { [cardIndex] in ...}. Note, no need for @State in your EditCardView
