Swift: Random name from List (CoreData)

I created a list where you can add and edit names. Now I want to generate a random name (on my second page / view). Could someone help me?

File.swift:

class NameStore : ObservableObject {
    @Published var names = [Name]()
}

ContentView.swift:

TextField("New Player", text: self.$newPlayer)
            Button(action: self.addNewPlayer, label: {Text("Add")
                .disabled(newPlayer.isEmpty)})


 func addNewPlayer() {
        nameStore.names.append(Name(id: String(nameStore.names.count + 1), newName: newPlayer))
        self.newPlayer = ""}
