I've been struggling to add an EditView to my list. I want to copy the list item into the EditView and then if the user saves changes, update the item.

The follow does not work, although it does compile. I guess you can't set the state during init? And then I do see the item in onAppear. Should I just keep the arugment passed in during intilization in another property and then update the state onAppear?

struct InitState: View {
    @State private var myState = "original"

    init(_ yourState:String) {
        self.myState = yourState
    }

    var body: some View {
        Text(myState)
            .onAppear {
            self.myState = "appear"
        }
    }
}

You can set the value of your @State var in your init like this:

init(_ yourState:String) {
    _myState = State(initialValue: yourState)
}

Thanks @roosterboy! Just to clear my head and potentially help other newbies.. the _ prefix comes from synthiszed code that the compiler creates for us to store the property wrapper?

The _ allows us to access the property wrapper object itself rather than the wrapped property.

So given...

@State private var myProperty = 1

myProperty gets us the integer being wrapped; _myProperty gets us the State wrapper around the integer.
