    <p>As Alex said, you have to add your database file as a resource to your project. This will instruct Xcode to bundle your database file in your .app. That file however is read-only, it's up to you to copy it over to your apps document folder (on the device or simulator, same thing), where it becomes writable basically. </p> <p>Here's the code that I use for this kind of thing below. The nice thing about this code is that it will automatically refresh the writable copy in your apps document folder whenever you change the "main" copy bundled in the .app. Use 'pathLocal' to open your (writable) database...</p> <p>The function below returns YES when the operation was successful (whether a copy was needed or not). You're free to change that with whatever suits you :)</p> <pre><code>NSString *pathLocal, *pathBundle; // Automatically copy DB from .app bundle to device document folder if needed - (BOOL)automaticallyCopyDatabase { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES); NSString *documentsDir = [paths objectAtIndex:0]; pathLocal = [documentsDir stringByAppendingPathComponent:@"mydb.sqlite"]; pathBundle = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"mydb.sqlite"]; NSFileManager *fileManager = [NSFileManager defaultManager]; NSDictionary *localAttr = [fileManager fileAttributesAtPath:pathLocal traverseLink:YES]; BOOL needsCopy = NO; if (localAttr == nil) { needsCopy = YES; } else { NSDate *localDate; NSDate *appDBDate; if (localDate = [localAttr objectForKey:NSFileModificationDate]) { NSDictionary *appDBAttr = [fileManager fileAttributesAtPath:pathBundle traverseLink:YES]; appDBDate = [appDBAttr objectForKey:NSFileModificationDate]; needsCopy = [appDBDate compare:localDate] == NSOrderedDescending; } else { needsCopy = YES; } } if (needsCopy) { NSError *error; BOOL success; if (localAttr != nil) { success = [fileManager removeItemAtPath:pathLocal error:&amp;error]; } success = [fileManager copyItemAtPath:pathBundle toPath:pathLocal error:&amp;error]; return success; } return YES; } </code></pre>

    1. COThat's fantastic. Thanks for this code Zoran. It will make things a bit (i.e. a lot) easier for me :) I particularly like that the code will refresh the writable copy when the main copy changes.

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).
