Call a NavigationLink programmatically?

Is it possible to call a Navigation Link programmatically?

It was possible, but now deprecated.

var link1 = NavigationLink("Link Text", destination: MyView1())
var link1 = NavigationLink("Link Text", destination: MyView2())

//Something like this
           Button(action: {

            if (option == 1){
                self.link1.presented?.value = true
            }
            else{
                self.link2.presented?.value = true
            }
        }

I don't know how to help with calling a Navigation Link but maybe I know the way to do what do you want..

Remember in SwiftUI we use structs, and they are static. For this reason you cannot set self.link1.presented?.value to true while the code is running.

To do that, you can first change this var to a @State var which means SwiftUI will make this var dynamic. With this in mind, you can handle which view you will show, simply saving which option is marked.

I modified your code to show this:

//begining of your struct
@State var selectedOption = 1 

//something changed the selectedOption
self.selectedOption = 2

//Here your NavigationLink ( use it without button)
NavigationLink("Link Text", destination: selectedOption == 1 ? View1 : View2)

Hope it helps!
