2次元配列から追加された配列を出力しようとすると "Team"オブジェクトの2次元配列があり、 "Team"の配列が1つあります。以下のコードでは、printにエラーがあります。2次元配列は即時に範囲外のエラーを指します
self.first_array = []
for i in 0..<json["LeagueStage"][0]["LeagueTable"].count {
guard let name = json["LeagueStage"][0]["LeagueTable"][i]["name"].string,
let id = json["LeagueStage"][0]["LeagueTable"][i]["id"].int,
let teamId = json["LeagueStage"][0]["LeagueTable"][i]["TeamID"].int,
let points = json["LeagueStage"][0]["LeagueTable"][i]["points"].string,

let wins = json["LeagueStage"][0]["LeagueTable"][i]["wins"].string,
let draws = json["LeagueStage"][0]["LeagueTable"][i]["draws"].string,
let defeits = json["LeagueStage"][0]["LeagueTable"][i]["defeits"].string,
let goalsfor = json["LeagueStage"][0]["LeagueTable"][i]["goalsfor"].string,

NSLocalizedFailureReasonErrorKey : NSLocalizedString("Veri Yok", value: "Hata", comment: "") ]
let err = NSError(domain: "ShiploopHttpResponseErrorDomain", code: 401, userInfo: dataFetch)
self.delegate?.errorUpdating(err as NSError)
return

let temp_team = Team(id: id,

)
self.first_array.append(temp_team)
}
}
self.teams.append(first_array)
print(teams[0][0].name)
初期化パート
// MARK: - Variables
var teams = [[Team]]()
var first_array = [Team]()
私は以下のように行うときに、それが動作するためfirst_arrayに問題がないことを確認しています。
self.teams = [self.first_array, self.first_array]
エラー：
fatal error: Index out of range
と私は
print(self.teams.popLast()?[0].name)
エラーログは正確に何ですか？ – Tushar
@Tushar致命的なエラー：インデックスが範囲外です – eonr
snake_caseではなく変数にlowerCamelCase名を使用するのが慣習です。また、 'let'定数と配列リテラルを' var'変数と 'append'呼び出しよりも優先させるべきです。 – Alexander
