swift - How to set text value when I used pickerview with multiple components -

i implemented demo of picker view multiple component

when set value text right want output

one 1 

but set

    1     1     2     2 

below code:

var  pickdata = [ ["one","two"],               ["1","2"]             ]   func pickerview(_ pickerview: uipickerview, numberofrowsincomponent component: int) -> int {    return pickdata.count }     func numberofcomponents(in pickerview: uipickerview) -> int  {      return 2    }  func pickerview(_ pickerview: uipickerview, titleforrow row: int, forcomponent component: int) -> string? {      return pickdata[component][row] } func pickerview(_ pickerview: uipickerview, didselectrow row: int, incomponent component: int) {    activetextfield.text = pickdata[component][row]     print(pickdata[component][row]) } 

like @david mentioned changing data structure dictionary right approach. if looking easy hack code help, though not best approach. output "one 1" , on can useful

    var pickdataindices = ["1", "2"]     var pickdata = ["one", "two"]   func pickerview(_ pickerview: uipickerview, numberofrowsincomponent component: int) -> int {      return pickdata.count }  func numberofcomponents(in pickerview: uipickerview) -> int {      return 1 }  func pickerview(_ pickerview: uipickerview, titleforrow row: int, forcomponent component: int) -> string? {      return pickdata[row] } func pickerview(_ pickerview: uipickerview, didselectrow row: int, incomponent component: int) {     activetextfield.text = pickdata[row]     print("%@ %@",pickdata[row], pickdataindices[row]) }
