【问题描述】：

我正在使用这段代码，当我打印（jsonResponse["data"]) 时，我非常快速轻松地从我的 API 收到返回。

但在第一个循环中我有一个无限循环。由于我的 API 的返回，我需要执行此循环。

有人可以帮助我吗？我正在使用相同的代码来获取课程数据并填充表格视图及其工作......但现在这个课程不适用于学校，我的 API 收到相同的结构：

SWIFT 代码：

func findSchools()
    let parameters: Parameters = [:]

    let headers: HTTPHeaders = [
        "ContentType": "application/json"
    ]

    API.consultAPI(headers: headers, type: .get, parameters: parameters, endpoint: "schools", completionSuccess:  (response) in

        if let responseValue: AnyObject = response.result.value as AnyObject? 
            let jsonResponse = JSON(responseValue)
            print(jsonResponse["data"])
            for (_, data) in jsonResponse["data"]
                print(data)

                if data["id"] != nil && data["name"] != nil
                    let school = School(id: data["id"].int!, name: data["name"].string!)
                    self.arraySchools.append(school)
                

            
        
        print(self.arraySchools)

    , completionFailure: (response) in
        if let responseValue: AnyObject = response.result.value as AnyObject? 
            let jsonResponse = JSON(responseValue)
            print(jsonResponse)
            AlertView.showAlert(view: self, message: "Error")
        
    )

API 返回：

【参考方案1】：

在代码中添加 .dictionaryValue 现在它正在工作（没有无限循环）：

 for (_, data) in jsonResponse["data"].dictionaryValue
    if data["id"] != nil && data["name"] != nil
      let school = School(id: data["id"].int!, name: data["name"].string!)
           self.arraySchools.append(school)
