    <p>I am trying to preload a sqlite database to my core data sqlite. I got first the sqlite from the simulator and then I filled some data in. </p> <p>The problem is that I can not get data from the filled .sqlite in my root Directory to the coreData .sqlite(this file is store in the simulator)</p> <p>I have tried with the apple example <a href="https://developer.apple.com/library/ios/samplecode/CoreDataBooks/Introduction/Intro.html" rel="nofollow">CoreDataBooks</a> but I does not work. </p> <pre><code>- (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (__persistentStoreCoordinator != nil) { return __persistentStoreCoordinator; } NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"MyData.sqlite"]; NSFileManager *fileManager = [NSFileManager defaultManager]; // If the expected store doesn't exist, copy the default store. if (![fileManager fileExistsAtPath:[storeURL path]]) { NSURL *defaultStoreURL = [[NSBundle mainBundle] URLForResource:@"MyData" withExtension:@"sqlite"]; if (defaultStoreURL) { [fileManager copyItemAtURL:defaultStoreURL toURL:storeURL error:NULL]; } } NSDictionary *options = @{NSMigratePersistentStoresAutomaticallyOption: @YES, NSInferMappingModelAutomaticallyOption: @YES}; __persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: [self managedObjectModel]]; NSError *error; if (![__persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&amp;error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } return __persistentStoreCoordinator; } - (NSURL *)applicationDocumentsDirectory { return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]; } </code></pre>

    1. COWhat exactly does not work? Are you sure that MyData.sqlite is added to your target, so that it is copied into the app bundle? Is `defaultStoreURL` nil or not? Does `copyItemAtURL:...` return YES or NO? If NO, what is the error?

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).
