次の JSON データの ObjectMapper を使用して迅速なオブジェクトを作成するのを手伝ってくれませんか?

[{
    "location": "Toronto, Canada",    
    "three_day_forecast": [
        { 
            "conditions": "Partly cloudy",
            "day" : "Monday",
            "temperature": 20 
        },
        { 
            "conditions": "Showers",
            "day" : "Tuesday",
            "temperature": 22 
        },
        { 
            "conditions": "Sunny",
            "day" : "Wednesday",
            "temperature": 28 
        }
    ]
}
]

使用している場合ObjectMapper:

import ObjectMapper

struct WeatherForecast: Mappable {
    var location = ""
    var threeDayForecast = [DailyForecast]()

    init?(_ map: Map) {
        // Validate your JSON here: check for required properties, etc
    }

    mutating func mapping(map: Map) {
        location            <- map["location"]
        threeDayForecast    <- map["three_day_forecast"]
    }
}

struct DailyForecast: Mappable {
    var conditions = ""
    var day = ""
    var temperature = 0

    init?(_ map: Map) {
        // Validate your JSON here: check for required properties, etc
    }

    mutating func mapping(map: Map) {
        conditions      <- map["conditions"]
        day             <- map["day"]
        temperature     <- map["temperature"]
    }
}

使用法：

// data is whatever you get back from the web request
let json = try! NSJSONSerialization.JSONObjectWithData(data, options: [])
let forecasts = Mapper<WeatherForecast>().mapArray(json)
