try this when you type you will have a filtered array
just connect this action method to textfield didchangeevent

  @IBAction func textFiledDidChange(_ textFiled : UITextField){
         var arr : [String] = ["a","ab","abc"]
         ///replace ("ab") with textfield.text!
         let filteredArr = arr.filter({$0.contains("ab")})
         print(filteredArr)
         /// filteredArr will contain now ["ab","abc"]    
         }

This might help,

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
        let array = ["g","d","s","a"]
        if array.contains(string) {
            // Typed character is in the array
        } else {
            // Typed character is not in the array
        }
        return true
    }
