This code works until I add the NavigationView (which I need for an app I am writing)... Basically I want the background of each segment to change to the color indicated. Once I wrap the NavigationView it stops working....any idea why?

import SwiftUI
import UIKit

enum PickerColor: String, Hashable, Identifiable, CustomStringConvertible, CaseIterable {
    case red
    case yellow
    case green
    case blue
    case violet

    var id: String { rawValue }
    var description: String { rawValue.capitalized }

    var color: Color {
        switch self {
            case .red: .red
            case .yellow: .yellow
            case .green: .green
            case .blue: .blue
            case .violet: .purple
        }
    }
}

struct ContentView: View {
    @State private var pickerColor: PickerColor = .red

  var body: some View {
    NavigationView {
      GeometryReader { geo in
        VStack {
          Picker(selection: $pickerColor, content: {
            ForEach(PickerColor.allCases) { color in
              Text(color.description)
                .tag(color)
            }
          }, label: EmptyView.init)
          .pickerStyle(.segmented)
          .tint(pickerColor.color)                                   // <- here
          .onAppear(perform: updatePickerColor)
          .onChange(of: pickerColor, updatePickerColor)

        }//vs
        Spacer()
      } //geo
      .padding()
    }
  }//nav

    func updatePickerColor() {
        let appearance = UISegmentedControl.appearance(for: .current)  // <- here
        appearance.selectedSegmentTintColor = UIColor(pickerColor.color)
    }
}
#Preview {
    ContentView()
}

Wow! you would have thought I would of gotten a deprecation warning...that works great! Thank you!!
