    <p>To start you need a data model to reflect what you want to save, in this case, some text and a date. So:</p> <pre><code>DatedText{ savedText:String dateSaved:Date } </code></pre> <p>To create a new <code>DatedText</code> object (without a custom class) do:</p> <pre><code>NSManagedObject *newDatedText; newDatedText=[NSEntityDescription insertNewObjectForEntityForName:@"DateText" inManagedObjectContext:theManagedObjectContext]; [newDatedText setValue:someText forKey:@"savedText"]; [newDatedText setValue:aDateObject forKey:@"dateSaved"]; NSError *saveError=nil; [theManagedObjectContext save:&amp;saveError]; if (saveError!=nil) { NSLog(@"[%@ saveContext] Error saving context: Error=%@,details=%@",[self class], saveError,saveError.userInfo); } </code></pre> <p>To retrieve a <code>DatedText</code> object with a specific date you create a fetch like so:</p> <pre><code>NSFetchRequest *fetch=[[NSFetchRequest alloc] init]; NSEntityDescription *testEntity=[NSEntityDescription entityForName:@"DatedText" inManagedObjectContext:self.moc]; [fetch setEntity:testEntity]; NSPredicate *pred=[NSPredicate predicateWithFormat:@"dateSaved==%@", targetDate]; [fetch setPredicate:[NSArray arrayWithObject:pred]]; NSError *fetchError=nil; NSArray *fetchedObjs=[theManagedObjectContext executeFetchRequest:theFetch error:&amp;fetchError]; if (fetchError!=nil) { NSLog(@" fetchError=%@,details=%@",fetchError,fetchError.userInfo); return nil; } </code></pre> <p><code>fetchedObjs</code> will now contain an array of all <code>DatedText</code> objects with the same <code>savedDate</code> as <code>targetDate</code>.</p>

    2. COHaving spent so much time looking at different code and paying with it its making much more sense coming back to this, however one thing about the managed object context. Where does it come from? Do I just need to declare one? Or is it more complex? And 'theFetch' is that not just what you declared as 'fetch'?

    3. COUse one of the Xcode template projects to create a core data based app. In the application delegate class, it will provide methods that will show you how you set up the core data stack.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
