    <p>Yes, more times than I care to recall.</p> <p>What this means is that Core Data's internals failed to connect to iCloud in some obscure and undocumented way. There's no recovery path or fix-- you just get to try again later. Those errors don't come from Magical Record or your code, they're an internal Core Data / iCloud failure.</p> <p>Here's the thing: <strong>This does not mean you did something wrong.</strong> And the corollary of that is, <strong>there is nothing you can do to fix it</strong>. When using iCloud with Core Data, <em>this just happens sometimes</em>, and you just have to deal with it. File a bug and pray to whatever god or gods you believe in that they fix it some day. Core Data with iCloud is just fundamentally flaky and you're encountering one of the most maddening parts.</p> <p><strong>Sometimes</strong> it helps to just try the call again. But Magical Record returns <code>void</code>, so detecting failure in code is not as simple as you might hope.</p> <p>During testing, it <em>might</em> help to delete all of your app's data from iCloud, to start clean. You do this in iOS at Settings --> iCloud --> Storage &amp; Backup --> Manage Storage --> (your app name here) --> Edit --> Delete All. Also be sure to check out <a href="http://developer.icloud.com/" rel="noreferrer">http://developer.icloud.com/</a> to see what's present in the cloud. Also, when you're having problems, be sure to delete your app from the device so that no old data is sitting around.</p>

    3. COYes but none that I have used seriously yet. Check out http://www.wasabisync.com and https://simperium.com, both of which work with Core Data. There's also Dropbox's API, but it won't work directly with Core Data.

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.
