ios - 如何从字典数组中获取数据 - swift

Question

如何从这个数组中获取数据？这里有一个包含一些键值对的数组，一些键包含一个字典数组。

 var dataArray = [
                ["teamName":"Arsenal",
                  "image":"imageName",
                  "nextMatch":"in 2 days",
                  "matches":[
                                ["oppositeTeam":"teamName",
                                 "matchTimings":"121212",
                                 "matchId":"ID 213432"],
                                ["oppositeTeam":"teamName",
                                 "matchTimings":"121212",
                                 "matchId":"ID 213432"]
                            ],
                  "fixtures":[
                                ["oppositeTeam":"teamName",
                                 "oppositeTeamScore":"7",
                                 "HomeTeamScore":"4",
                                 "HomeTeamCards":"True",
                                 "oppositeTeamCards":"false",
                                 "fixturesId":"ID 213432"],

                            ]
    ],["teamName":"Chelsea",
        "image":"imageName",
       "nextMatch":"in 2 days",
       "matches":[["oppositeTeam":"teamName",
                   "matchTimings":"121212",
                   "matchId":"ID 213432"],["oppositeTeam":"teamName",
                                           "matchTimings":"121212",
                                           "matchId":"ID 213432"]
        ],"fixtures":[["oppositeTeam":"teamName",
                       "oppositeTeamScore":"7",
                       "HomeTeamScore":"4",
                       "HomeTeamCards":"True",
                       "oppositeTeamCards":"false",
                       "fixturesId":"ID 213432"],["oppositeTeam":"teamName",
                                                  "oppositeTeamScore":"7",
                                                  "HomeTeamScore":"4",
                                                  "HomeTeamCards":"True",
                                                  "oppositeTeamCards":"false",
                                                  "fixturesId":"ID 213432"]
        ]
    ],["teamName":"India",
        "image":"imageName",
       "nextMatch":"null",
       "matches":[],
       "fixtures":[]
    ]]

我试过了，但我无法从这个数组中获取数据。

你需要像这样使用模型

struct Team {
    let teamName:String
    let image:String
    let nextMatch:String
    let matches:[Match]?
    let fixtures:[Fixture]?
}

struct Match {
    let oppositeTeam:String
    let matchTimings:String
    let matchId:String
}

struct Fixture {
    let oppositeTeam:String
    let oppositeTeamScore:String
    let HomeTeamScore:String
    let HomeTeamCards:String
    let oppositeTeamCards:String
    let fixturesId:String
}

接下来你需要在swift中了解Codeable，我在下面附上了一篇文章
