我想抓住“name”字段的 id ：“个人资料图片”。我使用 SwiftyJSON 来投射类型，到目前为止我设法做到了这一点：

 let dictionary = JSON(result)
 // print("albums **************\(dictionary)")
 if let data = dictionary["data"].array {
 print("data of profilePicture ******* \(data)")
 let index = data.index{ $0["name"] == "Profile Pictures" }

  }
 }

我可以看到 profilePicture 的名称，但现在我想抓住那个json对象的 id 。请帮忙。

Answer 2

let dictionary = JSON(result)
// print("albums ID are **************\(dictionary)")
if let data = dictionary["data"].array {
print("data of profilePicture ******* \(data)")

if let dict = data.first(where: { ($0["name"].string ) == "Profile Pictures" }) {
         let id = dict["id"]
         print("my desired id : ********* \(id)")
       }        
    }

从特定数组索引
