title: How to display next question in a label from an array of questions
body: <p><a href="https://i.stack.imgur.com/q0eyT.png" rel="nofollow noreferrer">Screenshot of current code in simulator, once the next button is clicked nothing changes and the question presented in the label remains the same</a></p>
  
  <p>I am building a survey app and want to display a list of questions through a label. However, my current code functionality presents the same question and I need to go to the next question once a button is tapped. Once the button is tapped id like for the label to present the next question in the array and also move the previously asked question to the end of the array. Here is my current Swift code for the function that is called when the button is tapped, as of now it presents the same question when the button is tapped:</p>
  
  <pre><code>         func nextQuestion() {
      var questions = [choice1, choice2, choice3]
      var y = 0
  
      questionLbl.text = questions[y].question
      questions.remove(at: y)
      y += 1
  
  
  
      var button = UIButton()
      var tags = [0,1,2,3]
  
      for quest in questions {
  
      }
  
      for idx in tags {
          button = choiceButtons[idx]
          if idx &lt; options.count {
              print("True! Index = \(idx) and options count = \(options.count)")
              button.setTitle(options[idx], for: .normal)
  
          }
          else {
              print("False! Index = \(idx) and options count = \(options.count)")
  
          }
      }
  
      print(questions)
  
  
  }
  </code></pre>
  
  <p>Here's my object model that contains the objects that are used for the array of questions:</p>
  
  <pre><code>      import Foundation
  
     var choice1 = User.Choice(question: "How old are you?", opt1: "12", opt2: "11", opt3: "10", opt4: "23")
     var choice2 = User.Choice(question: "What color are you?", opt1: "Black", opt2: "White", opt3: "Purple", opt4: "Brown")
     var choice3 = User.Choice(question: "What day is it?", opt1: "Monday", opt2: "Tuesday", opt3: "Friday", opt4: "Sunday")
  
  
  
     var users = [User]()
  
     struct User {
  var fields: Field
  var choices = [Choice]()
  
  struct Field {
      var firstname: String
      var lastname: String
      var email: String
  
      init(first: String, last: String, email: String) {
          self.firstname = first
          self.lastname = last
          self.email = email
      }
  }
  
  struct Choice {
      var question: String
      var opt1: String
      var opt2: String
      var opt3: String
      var opt4: String
  
      init(question:String, opt1: String, opt2: String, opt3: String, opt4: String) {
          self.question = question
          self.opt1 = opt1
          self.opt2 = opt2
          self.opt3 = opt3
          self.opt4 = opt4
      }
  }
  
  }
  </code></pre>
