Swift 3: JSON into tableview challenge

I have the following swift3 code:

    var tempNames = ["Alan","Dan","Mark","Jack","Kelly","Andrew","Paul"]

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "LabelCell", for: indexPath)

    let tempName = tempNames[indexPath.row]
    cell.textLabel?.text = tempName
    cell.detailTextLabel?.text = "Score"

    return cell
}

Which produces the following:

enter image description here

As you can see the names are static and the score simply is the word "score". The following JSON is returned from "https://str8red.com/jsonoverallleaderboard/":

[["shanu", "1056"], ["snookro", "828"], ["tingeypa", "709"], ["shaun", "620"], ["chrakers", "506"]]

What I would like to do is used the names and score from the above JSON instead of the static name and score already in use.

I have had a look around on stackoverflow and followed some guides without success. Any help on this would be appreciated, Alan.

  • Create a struct

    struct Player {
    let name : String
    var score : String
}

  • In the view controller create a data source array

    var players = [Player]()

  • After parsing the JSON having the array in the question (assuming it's in the variable jsonPlayers of type [[String]]) map the array to the struct

    players = jsonPlayers.map { Player(name: $0[0], score: $0[1]) }

  • In numberOfRows return 

    return players.count

  • In cellForRow assign the values to the labels

    let player = players[indexPath.row]
cell.textLabel?.text = player.name
cell.detailTextLabel?.text = player.score
