title: 'var' parameters are deprecated and will be removed in Swift 3
body: <p>Alright so I just update Xcode to 7.3 and now I get this warning:</p>
  
  <blockquote>
    <p>'var' parameters are deprecated and will be removed in Swift 3</p>
  </blockquote>
  
  <p>How to fix this when I need to use the var in this function:</p>
  
  <pre><code>public func getQuestionList(var language: String) -&gt; NSArray {
      if self.data.count &gt; 0 {
          if (language.isEmpty) {
              language = "NL"
          }
          return self.data.objectForKey("questionList" + language) as! NSArray
      }
  
      return NSArray()
  }
  </code></pre>
