swift - Retrieving values from 2D array in JSON string -

we fetch json data using rest protocol this.

jsonresult = try nsjsonserialization.jsonobjectwithdata(data!, options: nsjsonreadingoptions.allowfragments) 

which looks this:

jsonresult: (     {     board = "[[\"1:\",\"y\",\"u\",\"p\"]]"; }) 

from game board so:

     if let boardcontentarray = jsonresult[0]["board"] nsarray?{         print("boardcontentarray: \(boardcontentarray)" )     } else {         print("board element not nsarray")     } 

the boardcontentarray looks this: supposed 2d array 1 row , 4 columns @ moment, should should work given size.

[["1:","y","u","p"]] 

how can retrieve individual values of boardfromremote. imagine element @ 0,0 in 2d array way this:

boardcontentarray[0][0] 

this should return "1:", not case. exact syntax incorrect , won't compile. correct way retrieve element boardcontentarray variable?

the content of jsonresult[0]["board"] json string can decoded array nsjsonserialization. have first transform string nsdata, decode example:

do {     let boardcontentarray = "[[\"1:\",\"y\",\"u\",\"p\"]]" // string jsonresult[0]["board"]     if let boarddata = boardcontentarray.datausingencoding(nsutf8stringencoding),         let boardarray = try nsjsonserialization.jsonobjectwithdata(boarddata, options: []) as? [[string]] {             print(boardarray[0]) // ["1:", "y", "u", "p"]     } } catch let error nserror {     print(error) }
