NavigationLink initializer unused

Hello everybody,

I am trying to navigate from one view to another using NavigationView and NavigationLink.

I can't figure out what I am doing wrong, but the way I am doing it I get a warning saying:

"Result of NavigationLink<Label, Destination> is unused".

In fact, I can't navigate to the view I want to open.

Here is my code so far:

Code Block 
NavigationView {
	VStack {
		Button(action: {
			let observation = self.createObservation()
			self.records.addObservation(observation)
 			self.isPresented.toggle()
			
			NavigationLink(destination: ObservationDetails(observation: observation).environmentObject(self.records)) {
				EmptyView()
			}
			 }) {
				  Text("Classify")
			 }
}

Thank you for your help!
