I am trying to style the navigation Link button in SwiftUI right now it's the standard blue but I am trying to get it to Black and Bold similar to that of Fitness+ but the problem I encounter based on all the research I have done is finding a solution to the problem.

I hope someone can guide me.

Best, Imran

Not sure what you want but add .modifliers to want you want.

struct ContentView: View {
    var body: some View {
        NavigationView {
            NavigationLink {
                Text("New View")
            } label: {
                Text("Tapped Me")
            }
            .padding()
            .background(.black)
            .foregroundColor(.white)
            .font(.headline)
            .cornerRadius(10)
        }
    }
}

.buttonStyle also works

struct ContentView: View {
    var body: some View {
        NavigationView {
            NavigationLink {
                Text("New View")
            } label: {
                Text("Tapped Me")
            }
            .buttonStyle(.borderedProminent)
        }
    }
}

Using

.accentColour(Color.black) 

on the navigation view is what made the navigation link black.

Sorry You want the Colors in the Navigation Bar to be different color.

Then goto to the Asserts file and you will see AccentColor change this to the color you want in App struct use .tint(.accentColor). See below

@main
struct TestApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
                .tint(.accentColor)
        }
    }
}

PS .accentColour has been depreciated.
