ios - I would like to pass a 2d array of values to a second view in a Swift Single-View Application -

i trying create basic sudoku solver using xcode. currently, have 9x9 display of text fields gets converted 2d array , goes through solver i've made already. current dilemma want pass solved array second view , print sudoku board i'm not sure how 1.) correctly transition second view , 2.) how bring array print it.

i can't yet add images, storyboard contains 2 views. not connected currently. first has 9x9 display of text fields , button beneath no action associated. second has 9x9 display of labels , nothing else.

here entirety of code first view:

import uikit  class viewcontroller: uiviewcontroller {  @iboutlet var row1: [uitextfield]! @iboutlet var row2: [uitextfield]! @iboutlet var row3: [uitextfield]!  @iboutlet var row4: [uitextfield]! @iboutlet var row5: [uitextfield]! @iboutlet var row6: [uitextfield]!  @iboutlet var row7: [uitextfield]! @iboutlet var row8: [uitextfield]! @iboutlet var row9: [uitextfield]!   @ibaction func executesolver() {     var board = [[int]](count: 9, repeatedvalue: [int](count: 9, repeatedvalue: 0))     var board2 = [row1, row2, row3, row4, row5, row6, row7, row8, row9]      var row = 0; row < 9; ++row{         var rowe = board2[row];         var col = 0; col < 9; ++col{             var val = rowe[col].text;              if var intval = val.toint() {                 if intval > 0 && intval < 10 {                     board[row][col] = intval;                 }             }          }     }      var ss = solver(givenboard: board)     board = ss.getboard()  }   override func viewdidload() {     super.viewdidload()     // additional setup after loading view, typically nib. }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }   } 

you can consider using custom 2d struct.

why use this? gives subscripting.
also, if labels share common characteristics, might wise use array of outlets , use tags identify each instead of creating of outlets 1 one.

struct array2d<t> {       let columns: int       let rows: int       private var array: array<t?>      init(columns: int, rows: int) {         self.columns = columns         self.rows = rows         array = array<t?>(count: rows*columns, repeatedvalue: nil)     }      subscript(column: int, row: int) -> t? {         {             return array[row*columns + column]         }         set {             array[row*columns + column] = newvalue         }     }  }
