How do I bind the picker from a fetchResult?

@FetchRequest(entity: Team.entity(), sortDescriptors: [NSSortDescriptor(keyPath: \Team.teamName, ascending: true)]) var team: FetchedResults<Team>

Picker(selection: $updateTeammate.teamName, label: Text("Select team")) {
                            ForEach(team, id: \.id) { teams in
                                Text(teams.wrappedTeamName)
                            }
                        }

i was able to figure this out...

class UpdateTeammate: ObservableObject {

    @Published var teamName: [String] = [""]

    }

@State private var selectedTeam = 0

var body: some View {
Form {
Picker(selection: $updateTeammate.teamName[selectedTeam], label: Text("Select team")) {
                            ForEach(self.team, id: \.id) { teams in
                                Text(teams.wrappedTeamName).tag(teams.wrappedTeamName)
                            }
                        }
                    }
               }
