How to show NavigationLink as a button in SwiftUI

navigationswiftui

I've read a lot here about navigation in SwiftUI and tried a couple of things, but nothing is working as desired.

Basically, I have a view with a list of workouts and you can show a single workout by clicking on a row. This works as expected using NavigationView together with NavigationLink.

Now, I want a button on the detail view to start the workout. This should open a view with a timer. The view should be presented with the same animation as the detail view did and also show the name of the workout in the navigation bar with a back button.

I could implement this with a NavigationLink view on the details page, but the link always appears as a full width row with the arrow on the right side. I'd like this to be a button instead, but the NavigationLink seems to be resistant against styling.

struct WorkoutDetail: View {
    var workout: Workout

    var body: some View {
        VStack {
            NavigationLink(destination: TimerView()) {
                Text("Starten")
            }.navigationBarTitle(Text(workout.title))
        }
    }
}

struct WorkoutList: View {
    var workoutCollection: WorkoutCollection

    var body: some View {
        NavigationView {
            List(workoutCollection.workouts) { workout in
                NavigationLink(destination: WorkoutDetail(workout: workout)) {
                    WorkoutRow(workout: workout)
                }
            }.navigationBarTitle(Text("Workouts"))
        }
    }
}

Updated: Here's a screenshot to illustrate what I mean:

Current layout: 'Starten' with default right arrow. Desired layout: Blue button with yellow background.

You don't need to wrap your view inside the NavigationLink to make it trigger the navigation when pressed.

We can bind a property with our NavigationLink and whenever we change that property our navigation will trigger irrespective of what action is performed. For example:

struct SwiftUI: View {
    @State private var action: Int? = 0
    
    var body: some View {
        
        NavigationView {
            VStack {
                NavigationLink(destination: Text("Destination_1"), tag: 1, selection: $action) {
                    EmptyView()
                }
                NavigationLink(destination: Text("Destination_2"), tag: 2, selection: $action) {
                    EmptyView()
                }
                
                Text("Your Custom View 1")
                    .onTapGesture {
                        //perform some tasks if needed before opening Destination view
                        self.action = 1
                    }
                Text("Your Custom View 2")
                    .onTapGesture {
                        //perform some tasks if needed before opening Destination view
                        self.action = 2
                    }
            }
        }
    }
}

Whenever you change the value of your Bindable property (i.e. action) NavigationLink will compare the pre-defined value of its tag with the binded property action, if both are equal navigation takes place.

Hence you can create your views any way you want and can trigger navigation from any view regardless of any action, just play with the property binded with NavigationLink.

Thanks, hope it helps.
