SOLVED: How to conditionally navigate to a different view within a List or ForEach?

Hey everyone,

I have two different views that I want to display to the user depending on if a variable within a data array is marked as a "pod". I'm having trouble implementing the conditional within the List/ForEach, as no matter how I implement, the destination stays the same. Here's an example of the list:

List {
                    ForEach(getrealmdata.plantarray) { plants in
                        NavigationLink(destination: FloraPodDetailView(plantdata: plants, plantsensor: self.plantsensor)) {
                        PlantSensorRealmRow(plantsensor: self.plantsensor, plantdata: plants)
                        }
                    }.onDelete(perform: delete)
                }

The plantdata object contains a variable named sensortype that I want to read - this type is either "pod" or "plant".

Basically, I want the destination to go to PlantDetailViewNew if the plantdata.sensortype = plant, and it should go to FloraPodDetailView if plantdata.sensortype = pod.

Any ideas how I should construct this?

One way:

var body: some View {
    NavigationView {
        VStack(spacing: 20) {
            NavigationLink("Push (One)", destination: PushedView(text: "one"),
                           tag: 1,
                           selection: self.$selected)

            NavigationLink("Push (Two)", destination: PushedView(text: "two"),
                           tag: 2,
                           selection: self.$selected)

            NavigationLink("Push (Three)", destination: PushedView(text: "three"),
                           tag: 3,
                           selection: self.$selected)

            DelayButton(selected: self.$selected, tagId: 1)
            DelayButton(selected: self.$selected, tagId: 2)
            DelayButton(selected: self.$selected, tagId: 3)
        }
    }
}
