ios - Cannot subscript a value of type 'Set<String>' with an index of type 'Int' -

i having set of strings have data in it. when showing data set tableview, in cellforrowatindexpath method gives me above stated error. here code:

var tradeset: set<string> = ["tkai", "yndx", "pstg"]  func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecellwithidentifier("mytrade", forindexpath: indexpath) as! mytradetableviewcell      let objects = tradeset[indexpath.row]     cell.tradename.text = objects      return cell } 

any great. thank you!

a set not indexable, because order in elements of set listed irrelevant. should storing elements in array or different data structure. quick following (not recommended):

var tradeset: set<string> = ["tkai", "yndx", "pstg"]  func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecellwithidentifier("mytrade", forindexpath: indexpath) as! mytradetableviewcell      // not best data structure job tho     (index, element) in tradeset.enumerated() {         if row == index {             cell.tradename.text = element         }     }      return cell } 

these kind of scenarios suggest incorrect data structure/algorithm.
