Play sound on Apple Watch using SwiftUI

Hi all, Im making a standalone app for the Apple Watch and Im trying to play sound there, after trying all I could think of I only get errors with it. I wonder if I should import the sound file in a specific way or folder I made a simple test with the code Im running in app, the test sound is called 5.wav and is in assets folder, tried also in other folder or in folder inside assets folder The message is not being printed and get some error related to sound not being loaded "Watch App[53825:678174] void * _Nullable NSMapGet(NSMapTable * _Nonnull, const void * _Nullable): map table argument is NULL "

import SwiftUI
import AVFoundation

struct ContentView: View {
    @State var avp:AVAudioPlayer?
    var body: some View {
        VStack {
            Button("PLAY")
            {
                guard let url = Bundle.main.url(forResource: "5", withExtension: "wav")else
                {
                    return
                }
                try? avp=AVAudioPlayer(contentsOf: url)
                avp?.play()
                print("printing")
            }
        }
        .padding()
    }
}
