I'm trying to access the data downloaded from a website which looks like this:

{"quizzes":[

{"id":1, "question": "Can't solve this :("},

{"id":2, "question": "Someone help pls"}]}

The data downloaded looks way more complex, with more values, more keys, and some keys being associated to another dictionary of Key:String, but since i can't even access the most simple fields I thought i would start with this.

I'm using JSONSerialization, so my question is:

If I want to create a variable where i can save the downloaded data... Which would be it's type? I would say [String:[String:Any]], but I'm not sure if "quizzes" represents a key on this specific key, since the data starts with '{' and not with '['.

Instead of using JSONSerialization one could use JSONDecoder.

Example

struct Question: Decodable {

    let id: Int

    let question: String

}



struct Quiz: Decodable {

    let quizzes: [Question]

}

Assuming jsonStr is a string with the JSON in your question:

if let jsonData = jsonStr.data(using: .utf8) {

    if let quiz = try? JSONDecoder().decode(Quiz.self, from: jsonData) {

        for question in quiz.quizzes {

            print("(question.id) "(question.question)"")

        }

    }

}

Output

1 "Can't solve this :("

2 "Someone help pls"
