title: CoreData syntax for inserting a new object
body: <p>Can someone tell me what is the difference between the two lines below? Don't they both create a new object that can be inserted? Thank you!</p>
  
  <pre><code>let author = Author(context: moc)
  </code></pre>
  
  <p>and</p>
  
  <pre><code>let author = NSEntityDescription.insertNewObject(forEntityName: "Author", into: self.moc!) as! Author
  </code></pre>
