Error assigning a string array in Swift

Question

I am programmatically presenting a view controller and I am changing the value of a string array with a string array value stored in my SQL (gameGAMETABLEDATA). I am stuck on this error "Cannot assign a value of type 'String' to value of type [String]". I am not sure why this is happening. When I println(gameGAMETABLEDATA[index]), I get a string array, but swift is telling me that it is not a string array. Any help would be greatly appreciated.

var gameGAMETABLEDATA: [String] = []


override func viewDidLoad() {
    super.viewDidLoad()

            let index = indexPath.row

            //Error below!!! "Cannot assign a value of type 'String' to value of type [String]"
            GameViewController.tableData = gameGAMETABLEDATA[index]

        }

println(gameGAMETABLEDATA)[index] returns:

[cricket3.png, cricket1.png, cricket1.png, cricket1.png, cricket1.png, cricket1.png, cricket1.png]

if tableData is String array and gameGAMETABLEDATA is String array then use direct resultController.tableData = gameGAMETABLEDATA[index] or describe more — Ashish Kakkad

Your array declaration seems wrong. Do like below.

var gameGAMETABLEDATA: [[String]] = []

override func viewDidLoad() {
    super.viewDidLoad()
    let index = indexPath.row

    //Error below!!! "Cannot assign a value of type 'String' to value of type [String]"
    GameViewController.tableData = gameGAMETABLEDATA[index]

        }

Your gameGAMETABLEDATA should be an Array of array as per your code.

gameGAMETABLEDATA declared as array of strings (e.g. ["game 0", "game 1"]) it is ok that gameGAMETABLEDATA[i] is String (following our example gameGAMETABLEDATA[0] == "game 0")

If you need to show all contents of Game Table Data just remove braces in this line: GameViewController.tableData = gameGAMETABLEDATA If you need some specific data for single game you should use other data structure. Like

let gamesData = 
[
 ["title of game 0", "top score of game 0"],
 ["title of game 1", "top score of game 1"]
]

This structure is array of arrays of strings and particular array of strings can be accessed by gamesData[0] — this expression returns ["title of game 0", "top score of game 0"]

You are passing a single string to your tableData property. You can pass the whole array:

GameViewController.tableData = gameGAMETABLEDATA

wrap the result in square brackets to nest the string in an array:

GameViewController.tableData = [gameGAMETABLEDATA[index]]

or define your gameGAMETABLEDATA property as a matrix:

gameGAMETABLEDATA: [[String]]
