How to get data from local JSON file in swift?

I want to get data from local JSON file. It's look like:

[
[
{
  "link": "link1",
  "answers": [
    "answer1",
    "answer2",
    "answer3",
    "answer4",
    "answer5"
  ],
  "questions": "question1"
},
{
  "link": "link2",
  "answers": [
    "answer1",
    "answer2",
    "answer3",
    "answer4",
    "answer5"
  ],
  "questions": "question2"
}
]
]

How can I take separately each element? And how can I take separately each answer? I want to use answers in table view. indexPath.row[1] = answer1 indexPath.row[2] = answer2...

let url = Bundle.main.url(forResource: "info", withExtension: "json")!
    do {
        let jsonData = try Data(contentsOf: url)
        let json = try JSONSerialization.jsonObject(with: jsonData)
        print(json)

        //let current = json["title"] as! [String: [String:Any]]

        //for (key, currency) in current {
            //let quest = currency["title"] as! String
            //let img = currency["image"] as! String
            //let ans = currency["answers"] as! [String]
        //}
    }
    catch {
        print(error)
    }

}

You have to take care of the JSON structure to get the correct values. See the below snippet to see how you can reach your questions in JSON.

    let url = Bundle.main.url(forResource: "File", withExtension: "txt")!
    do {
        let jsonData = try Data(contentsOf: url)
        let json = try JSONSerialization.jsonObject(with: jsonData) as! [[[String: Any]]]

        if let question1 = json.first?[0] {
            print( question1["link"] as! String)
        }

        if let question2 = json.first?[1] {
            print( question2["link"] as! String)
        }
    }
    catch {
        print(error)
    }

So now, you know how to reach the actual data. You should create some Question class. Then you should retain a list of questions parsed from the file and use that list for your TableView.
