与ObservableObject的问题

Question

我有一个设置为ObservableObject的类：

class MatchData : Identifiable,  ObservableObject {
    
    @Published var id: Int
    
    @Published var LocalPlayer: Player
    @Published var RemotePlayer: Player
    
    init(_ match: GKTurnBasedMatch, id: Int) {
        
        let local = match.participants[0].player!
        let remote = match.participants[1].player ?? GKPlayer()
        //self.id = match.matchID
        
        LocalPlayer = Player(Alias: local.alias
            , DisplayName: local.displayName
            , TeamPlayerId: local.teamPlayerID
            , PlayerId: local.gamePlayerID
        )
        
        RemotePlayer = Player(Alias: remote.alias
            , DisplayName: remote.displayName
            , TeamPlayerId: remote.teamPlayerID
            , PlayerId: remote.gamePlayerID
            
        )
        self.id  = id
    }
}

然后我在另一个班级里：

@ObservedObject var MatchList: [MatchData] = [MatchData]()

但是，这会产生错误：

泛型结构“ObservedObject”要求“MatchData”符合“ObservableObject”

我相信我的类符合ObservableObject，但是我似乎无法消除这个错误。

您可以为MatchData集合创建显式的可观察类，如

class MatchList: ObservableObject {
   @Published var data: [MatchData] = [MatchData]()
}

然后您就可以在视图中使用

@ObservedObject var matchList: MatchList
