Swift new view with old array

I have an problem with my code. I want to generate a random name with the array (Name.Store.names) which I used in my contentView but I get an error (var playerNames = NameStore.names).

struct GameView: View {
    
    @State var number = Int.random(in: 0...6)
    @State var randomName = Int.random(in: 0...2)
    
    let tasks = ["..."]
  
    var playerNames = NameStore.names

    var body: some View {
        ZStack {
            RadialGradient(...)
                .edgesIgnoringSafeArea(.all)
            
            VStack {
                Spacer()
                Text("\(playerNames[randomName]) \(tasks[number])")
                  
                Spacer()
                Button(action: {
                    self.number = Int.random(in: 0..<self.tasks.count)
                    self.randomName = Int.random(in: 0..<self.playerNames.count)
                }) {
                    Text("New Task")
                       
                }
            }
        }
    }
}

struct GameView_Previews: PreviewProvider {
    static var previews: some View {
        GameView()
    }
}
