在地图JSON中搜索

Question

我需要在这个JSON中实现搜索，我试过这样做，但它给了我错误。下面是我映射的代码和模态类。

在尝试了所有可能的方法之后，我仍然无法解决此错误。

我的搜索代码：

 self.company = self.companyDetails.filter{ _ in self.companyDetails.company_name.range(of: searchKey) }

显示错误：

  

类型'[companiesDetail]'的值没有成员'company_name'

Alamofire.request("http://34.210.142.70/isdental/api/v2.0/home/companies", method: .get, parameters: nil, encoding: URLEncoding.default, headers: params).responseObject  { (response:DataResponse<ContactRealm>) in            
   let ContactsRes = response.result.value        
   self.companyDetails = ContactsRes?.companies as! [companiesDetail]           
   self.company = ContactsRes?.companies  as! [companiesDetail]        
}

以下是我的JSON：

下面是我的映射类：

 import ObjectMapper

    mutating func mapping(map: Map) {   
       self.companies <- map["companies"]

   init?(map: Map) {     
   }

   var company_id : Int?
