title: How to instantiate a dictionary by using for loop (swift)
body: <pre><code>private var selectedButtonArray = [UIButton]() 
  private var buttonStepperDictionaryArray = [NSMutableDictionary]()
  
  func appendToButtonStepperDictionaryArray(ixSelectionItem: IxSelectionItem...){
      for iSelectionItem in selectedButtonArray{
          buttonStepperDictionaryArray.append("buttonDesc":iSelectionItem.button.text,"dsds":iSelectionItem.button.tag)
      }
  }
  </code></pre>
  
  <p>The result should look like this:</p>
  
  <pre><code>[{"buttonDesc":"abc","buttonTag":1},
   {"buttonDesc":"bcd","buttonTag":2},
   {"buttonDesc":"ddd","buttonTag":3}]
  </code></pre>
  
  <p>How can I do that?</p>
