Set the Navigation Bar Title Font

This is a SwiftUI question, not UIKit

I'm trying to set a different font for the navigation bar title using SwiftUI. My suspicion is that this isn't supported yet. Here's what I've tried:

var body: some View {  NavigationView {    .navigationBarTitle(Text("Dashboard").font(.subheadline), displayMode: .large)  }}

No matter what I do with the .font settings, it doesn't change the text. I've also tried setting a custom font and removing the displayMode property.

Has anyone been able to get this to work?
