ios – 在swift 3中将json解析为数组

我是 swift的新手,我从请求中得到一个json,但我无法解析.我正在尝试获取json信息并创建在mapkit上使用注释的坐标

下面是我回来的json

{
    coord =     [
                {
            islocationactive = 1;
            latitude = "37.8037522";
            locationid = 1;
            locationsubtitle = Danville;
            locationtitle = "Schreiner's Home";
            longitude = "121.9871216";
        },{
            islocationactive = 1;
            latitude = "37.8191921";
            locationid = 2;
            locationsubtitle = "Elementary School";
            locationtitle = Montair;
            longitude = "-122.0071005";
        },{
            islocationactive = 1;
            latitude = "37.8186077";
            locationid = 3;
            locationsubtitle = "Americas Eats";
            locationtitle = "Chaus Restaurant";
            longitude = "-121.999046";
        },{
            islocationactive = 1;
            latitude = "37.7789669";
            locationid = 4;
            locationsubtitle = "Cheer & Dance";
            locationtitle = Valley;
            longitude = "-121.9829908";
        }
    ] }

我尝试解析的代码就是这个

let task = URLSession.shared.dataTask(with: request as URLRequest){
            data,response,error in
 
            //exiting if there is some error
            if error != nil{
                print("error is \(error)")
                return;
            }
 
            //parsing the response
            do {
                //converting resonse to NSDictionary
                var teamJSON: NSDictionary!
 
                teamJSON =  try JSONSerialization.jsonObject(with: data!,options: .mutableContainers) as? NSDictionary
                print(teamJSON)
                //getting the JSON array teams from the response
                let liquidLocations: NSArray = teamJSON["coord"] as! NSArray
 
                //looping through all the json objects in the array teams
                for i in 0 ..< liquidLocations.count{
 
                    //getting the data at each index
      //              let teamId:Int = liquidLocations[i]["locationid"] as! Int!
 
                }
 
            } catch {
                print(error)
            }
        }
        //executing the task
        task.resume()

但不是我尝试工作.我想得到纬度,经度并在地图上创建一个注释

谢谢您的帮助

解决方法

您可以尝试使用与@Niko Adrianus Yuwono相同的代码,但进行了一些更改,因此您将获得teamid作为整数

do {
        let data : NSData = NSData() // change your data variable as you get from webservice response
        guard let teamJSON =  try NSJSONSerialization.JSONObjectWithData(data,options: []) as? [String: Any],let liquidLocations = teamJSON["coord"] as? [[String: Any]]
            else { return }
 
        //looping through all the json objects in the array teams
        for i in 0 ..< liquidLocations.count{
            let teamId: Int = (liquidLocations[i]["locationid"] as! NSString).integerValue
            print(teamId)
        }
 
    } catch {
        print(error)
    }
