title: Core Data not saving directly to sqlite
body: <p>In the old days, when I developed iOS app using Core Data for &lt; iOS 7, I remembered that if I am not mistaken, sqlite file in emulator was not saved directly. I need to go to Home in iPad, then the sqlite file was updated.</p>
  
  <p>Now I faced same thing. I observe my sqlite file never get modified, <strong>only the SHM and WAL file</strong>. So how can I check my data in sqlite? </p>
  
  <p>The data is being persisted by Core Data since my app can fetch the new inserted/updated data.</p>
  
  <p>Any advices from anyone?</p>
