I am having a State in SwiftUI Mac OS, which stores my active selection of a Navigation View. Everything is working with the Navigation view.
Now I have created a new class which confirms to the Observable Object. In some child views I will make a change to that object. When the change is done, my Navigation view updated the object aswell, which is the feature of Observable Object as far as I understand.
What I now want to achieve is that the Observable object changes my @State in my Navigation view.
That is my declaration in my Navigation view. UserData stores a int aswell, which should be set to the selection on change.
@EnvironmentObject var userData: UserData
@State var selection: Int?
So userData.active = 2, should set selection = 2 aswell. Is there a onChange event I can trigger?
I am using that @State selection for a Binding in my Navigation Link.
NavigationLink(destination: SecondContentView(), tag: 0, selection: self.$selection)
{
Second approach, would be using that userData.active : Int directly as State. However, I am passing that selection State as Binding and it gives me an error when passing the variable of an EnvironmentObject as Binding.
