title: How to pass an error pointer in the Swift language?
body: <p>I am attempting to pass an error pointer in swift and am unable to do so. The compiler complains that "NSError is not convertible to 'NSErrorPointer'".</p>
  
  <pre><code>var error: NSError = NSError()
  var results = context.executeFetchRequest(request, error: error)
  
  if(error != nil)
  {
      println("Error executing request for entity \(entity)")
  }
  </code></pre>
