    <p>The answer is a bit tricky but this always works for me. This is for a <strong>clean</strong> installation of a new compatible .sqlite file, <strong>not a migration</strong>!</p> <p>launch simulator, delete the app and the data (the popup after you delete the app).</p> <p>quit simulator</p> <p>open X-Code, after making any edits to your data model</p> <p>if needed update the datamodel version:</p> <ol> <li><code>Editor &gt; Add Model Version...</code></li> <li>set your prefs in the dialog that appears (counting up is preferable)</li> <li>click on the {appname}.xcdatamodeld then in the far right pane</li> <li>click the left icon of the 3 icons on top of the far right column</li> <li>under <code>Versioned Core Data Model</code> select the one you just created</li> </ol> <p>delete the <code>{appname}.sqlite</code> file (or back it up, remove it from project folder, and delete reference)</p> <p>clean the app (<code>Product &gt; Clean</code>)</p> <p>Run the app in a simulator (for this tutorial I will assume 4.2)</p> <p>While the simulator is running, in a Finder window, navigate to: <code>{home} &gt; Library &gt; Application Support &gt; iPhone Simulator &gt; 4.2 &gt; Applications &gt; {random identifier} &gt; Documents &gt; {appname}.sqlite</code></p> <p><strong>Copy</strong> this file to another location</p> <p>Stop running your app in X-Code</p> <p>Drag and drop the {appname}.sqlite file into the files list in X-Code.</p> <p>In the dialog that pops up, make sure the <code>copy to folder</code> checkbox, is checked.</p> <p><code>Product &gt; Clean</code></p> <p>Then run the app in the simulator again</p> <p>Now you should have a working sqlite file!</p> <p>Cheers, Robert</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
