如何使用Alamofire从多个响应中提取特定数据

Question

我正在构建一个应用程序以学习敏捷。我的应用正在向yelpApi发送请求。响应根据位置显示多个餐厅的信息（名称，位置，地址等）。我可以显示一家餐厅的餐厅名称，地址和类型。如何显示多个餐厅的数据。我创建了数组并追加，但我总是在获取一家餐厅的数据。

感谢所有答案

我的班级模型

'''

Class ApiRestaurantDataModel {

    var restaurantName : String?
    var restaurantLocation : String?
    var restaurantType : String?
    var restaurantRating : Int?

    init(restaurantName: String?, restaurantLocation: String?, restaurantType: String?) {
        self.restaurantName = restaurantName
        self.restaurantLocation = restaurantLocation
        self.restaurantType = restaurantType
    }


}
