thanks !

you need this:

 var goodanswers = ["one", "two", "three"]  var textfields:[int:uitextfield]!   override func viewdidload() {     super.viewdidload()     self.textfields = [0:textfield, 1:textfield2]  }  @ibaction func btnclick(sender: anyobject) {     for(index, answer) in goodanswers.enumerate() {         if textfields[index]?.text == answer {             textfields[index]?.backgroundcolor = uicolor.greencolor()         }         else {             textfields[index]?.backgroundcolor = uicolor.redcolor()         }     } } 

update:

if want have answers change code this:

declare new property:

var collectionofgoodanswers: [int : [string]]! 

and in viewdidload() method:

self.collectionofgoodanswers = [0:  ["hello", "world"],                                         1:  ["welcome", "friend"]] 

and implement click action:

@ibaction func btnclick(sender: anyobject) {     for(index, _) in collectionofgoodanswers.enumerate() {         guard let goodanswer = collectionofgoodanswers[index] else { return }         guard let answer = textfields[index] else { return }         guard let text = answer.text else { return }          if goodanswer.contains(text) {             textfields[index]?.backgroundcolor = uicolor.greencolor()         }         else {             textfields[index]?.backgroundcolor = uicolor.redcolor()          }     } } 

hope helps.
