Question

我在对应用程序中的某些代码进行故障排除时遇到困难。总而言之，我相信我能够成功地查询特定集合中的文档，但是它没有填充我的数组。我试图重新构建整个代码以进行故障排除，但是我很茫然。我有一个类似的视图控制器，它使用类似的代码，并且运行良好，这就是为什么我在弄清楚这一点时会遇到麻烦，并且这让我很生气。

我很想提出一些有关如何解决问题的想法。并提前感谢您！！

函数中的代码

var gamesArray = [Games]()

....

 private func  loadGames() {

SVProgressHUD.show()
let collectionReference = 
db.collection("games").whereField("playerid", isEqualTo: "30019")
collectionReference.addSnapshotListener { documentSnapshot, error in

    if (documentSnapshot?.isEmpty)! {
        print("Oops: No Data found in query")
        SVProgressHUD.dismiss()
    } else {

        guard let documents = documentSnapshot?.documents else {
            return
        }
        //2. This is part of the code is firing
        //But my Array is not populating with any data (See Screen 
Shot)
        print("Success: Query Data Found")
        self.gamesArray = documents.compactMap({Games(dictionary: 
$0.data())})
        print(self.gamesArray)
        self.reloadMyPlayers()

       }
    }
}

func reloadMyPlayers() {
    DispatchQueue.main.async {
        self.gameView.reloadData()
    }
    SVProgressHUD.dismiss()
 }

这是我的游戏结构

import Foundation
import FirebaseFirestore

protocol DocSerializable {
 init?(dictionary:[String : Any])
 }

struct Games {

var playerid:String
var opponent:String
var season:String
var gamedate:Timestamp
var submitdate:Timestamp

var dictionary:[String : Any] {
     return [
      "playerid" : playerid,
      "opponent" : opponent,
      "season" : season,
      "gamedate" : gamedate,
      "submitdate" : submitdate
     ]
   }
 }

extension Games : DocSerializable {
 init?(dictionary: [String : Any]) {
  guard let playerid = dictionary["playerid"] as? String,
     let opponent = dictionary["opponent"] as? String,
     let season = dictionary["season"] as? String,
     let gamedate = dictionary["gamedate"] as? Timestamp,
     let submitdate = dictionary["submitdate"] as? Timestamp
     else {return nil}

    self.init(playerid: playerid, opponent: opponent, season: season, gamedate: gamedate, submitdate: submitdate)
   }
  }
