I am trying to get response values from an API url using Alamofire. I created a data model and the response is fine but I am getting null for poster_path and release_date. I was wondering how can handle JSON response correctly. here is my code:
let decoder: JSONDecoder = {
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
return decoder
}()
func fetchMovies( completion: @escaping(MovieResponse?, AFError?) -> Void) {
let url = URL(string: "url")!
let params = [:]
AF.request(url, method: .get , parameters: params)
.responseDecodable(of: Data.self, decoder: decoder) { response in
switch response.result {
case .success(let movies):
completion(movies, nil)
case .failure(let error):
completion(nil , error)
}
}
}
Response:

>Solution :
Remove the entire CodingKeys enum in Movie.
The convertFromSnakeCase strategy does already the key mapping.
And don’t declare all properties carelessly as optional. Serious services like themoviedb send very consistent data. At least most likely a movie has always a title and an identifier.
