I'm working on Movie app for practice and I'm stuck on parsing JSON into Array. I'm using Alamofire for HTTP request and Unboxer for deserializing JSON into Object.
I'm getting JSON response in this form.

Everything is working fine, i'm getting JSON response in String type over Alamofire request but the problem starts when i need to parse JSON response into array type.
public class APIManager : NSObject {
static public func GetPopularMovies(){ // Get all POSTS
Alamofire.request(APIRouter.GetPopularMovies()).responseJSON { response in
if let json = response.result.value as? Array<Dictionary<String, Any >>
{
var movies : [Movie]
movies = try! unbox(dictionaries: json)
print("GetPopularMovies() -> Executed")
print("JSON: \(json)") // JSON Response
} else {
print(response.result.value!)
}
}
}
}
The if statemant is always false, and i don't know in which type of array should I parse JSON response.
Here are the models i'm using to deserialize JSON with Unboxer.
struct Movie {
let id : Int
let original_title : String
let overview : String
}
extension Movie : Unboxable {
init(unboxer : Unboxer) throws {
self.id = try unboxer.unbox(key: "id")
self.original_title = try unboxer.unbox(key: "original_title")
self.overview = try unboxer.unbox(key: "overview")
}
}
struct Genre {
let id : Int
let name : String
}
extension Genre : Unboxable {
init(unboxer : Unboxer) throws {
self.id = try unboxer.unbox(key: "id")
self.name = try unboxer.unbox(key: "name")
}
}
It would be great if you could help me with resolving this problem, I've never had problem like this before because probably i was using API's with smaller and easier responses.
Thank you guys very much!
I think you are using array of dictionary for your response in this line -
Array<Dictionary<String, Any >>
But your json response is a dictionary which contains the array of results. If you want the parse the results array then you must parse only the results not the conplete response like this -
if let json = response.result.value as? [String: Any]
{
let results = json["results"] as? [[String: Any]]
let movies : [Movie] = try! unbox(dictionaries: results)
print("GetPopularMovies() -> Executed")
print("JSON: \(json)") // JSON Response
} else {
print(response.result.value!)
}
