title: Bundling a Realm with an App section
body: <p>I am trying to bundle a realm file with my app. I followed steps 1-5, but I am not clear on step 6. It says to copy the file back to the document folder, especially if it will be edited by the users. </p>
  
  <p>Assuming, the copy statement goes inside the AppDelegate (similar to how it is done in the sample migration code), and the file is copied, what will happen the next time the app is launched? will it copy the file again, and overwrite it? Am I missing something?</p>
  
  <p>Do I need to run it once before I ship the app, and then remove the code from the app delegate?</p>
  
  <p>EDIT: this question is regarding realm-swift</p>
