title: How to migrate core data model from 'xcdatamodel' to 'xcdatamodeld'?
body: <p>I am using core data in <code>XCode 11</code> with the <code>MagicalRecord</code> library. My records are lost after app update. I have also tried to migrate the core data model from <code>xcdatamodel</code> to <code>xcdatamodeld</code>. Has anyone else faced the same issue? Any help would be appreciated. </p>
