Swift onDelete on nested Arrays

I have the following code:

struct FirstView: View {

    @State var idArray: Array<String> = ["a", "b", "c"]

    var body: some View {
         SecondView(idArray: $idArray)
    }
}


struct SecondView: View {

    @Binding var idArray:Array<String>

    var body: some View {
        List(){
            Section{
                ForEach(0..<self. idArray.count, id: \.self){id in
                    Text(self.idArray[id])
                }.onDelete(perform: deleteItem)
            }
        }
    }

    func deleteItem(at offsets: IndexSet) {
         self.idArray.remove(atOffsets: offsets)
    }
}

The problem: When performing a delete it does not delete the right element but rather the last one.

I think that the @Binding is the issue here as before I did not have the List as an own component and everything in one struct and it worked. The own component would help reduce code redundancy in the future.

List {
    Section{
        ForEach(self.idArray, id: \.self){ id in
            Text(id)
        }.onDelete(perform: deleteItem)
    }
}
