Looping not working

[vvrinne]

I am following the example for looping through a JSON response. Creating the initial JSON object works and I am able to fetch properties. When I try to loop through the root Dictionary XCode complains that: Type 'JSON' does not conform to protocol 'SequenceType'

I am using Alamofire to make the HTTP request. Here is my response handler:

request.responseJSON { (request, response, data, error) in
let json = JSON(object: data!)
for (key: String, subJson: JSON) in json {
println(subJson)
}
}

Yeah I am just using the master version. Isn't it a bit of a problem that the readme is not in sync with the code though?

I did eventually get looping to work in this fashion:

       if let dataArray  = json["data"].arrayValue {
            for entry: JSON in dataArray {
                let id = entry["id"]
                let title = entry["title"]
                println("\(id) : \(title)")
            }
        }

@vvrinne You code will loop twice, one time to get arrayValue: [JSON], one time to loop the arrayValue to get each entry
In readme:

//If json is .Array
//The `index` is 0..<json.count's string value
for (index: String, subJson: JSON) in json {
//Do something you want
}

You should code like this:

for (_, entry) in json["data"] {
  let id = entry["id"]
  let title = entry["title"]
  println("\(id) : \(title)")
}

OR：

for var index = 0; index < json["data"].cout; index++ {
  let entry = json["data"][index]
  let id = entry["id"]
  let title = entry["title"]
  println("\(id) : \(title)")
}
