Expected to decode Dictionary but found an array instead.", underlyingError: nil))












0















I trying to parse some json using swift 4 and using decode. What I am confused is on the




Expected to decode Dictionary<String, Any> but found an array instead.", underlyingError: nil))




I am new to using decode and new to swift in general so I was wondering why I would be getting this error, I assume I am not really defining my structs the right way.



This is how I am defining my strucs



struct QuizDesc: Decodable {

    let title: String

    let desc: String

    let questions: [Questions]

}



struct Questions: Decodable {

    let text: String

    let answer: Int

    let answers: [Answers]

}



struct Answers: Decodable {

    let answerOne: String

    let answerTwo: String

    let answerThree: String

    let answerFour: String

}


And this is how I am using the decode function



let jsonString = "http://tednewardsandbox.site44.com/questions.json"



guard let url = URL(string: jsonString)else {return}



URLSession.shared.dataTask(with: url) { (data, response, err) in

    guard let data = data else{return}



    do {

        let quiz = try JSONDecoder().decode(QuizDesc.self, from: data)



        print(quiz.title)

    } catch let jsonErr {

        print("Error", jsonErr)

    }

}.resume()

          Your JSON is an array of QuizDesc. Change QuizDesc.self to [QuizDesc].self. Then rename quiz to quizzes.
