Cannot Pre-Populate Core Data with SQLite

I have a list app that I'm working on that I want the core data to be pre-populated, so when a user launches the app for the first time, tableview is populated with some default lists, rather than empty tableview. I searched through a lot of questions and followed their steps, but the app always launches with empty tableview.

Here are the insufficient steps I'm taking. I'll also leave some links to where I got these steps from, if that helps.

1. Disable .sqlite-wal, and .sqlite-shm, to save data directly into .sqlite. NSDictionary *options = @{ NSSQLitePragmasOption : @{@"journal_mode" : @"DELETE"} }; Link


2. Run the app on a simulator and populate .sqlite file the way I want it to be populated. I used the Firefox SQLite Manager to make sure that .sqlite file is populated.


3. Find the .sqlite file location with NSLog(@"StoreURL Path %@", storeURL.path); , and copy the file from Finder into app directory, with Destination box unchecked. Link - at "Doctor, you’re needed in Xcode"

   In persistentStoreCoordinator in AppDelegate Link

   
   

   
   - (NSPersistentStoreCoordinator *)persistentStoreCoordinator {
   
   
       if (_persistentStoreCoordinator != nil) {
           return _persistentStoreCoordinator;
       }
   
       _persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc]
           initWithManagedObjectModel:[self managedObjectModel]];
       NSURL *storeURL = [[self applicationDocumentsDirectory] 
           URLByAppendingPathComponent:@"App_Name.sqlite"];
   
       NSLog(@"StoreURL Path %@", storeURL.path);
   
       // If the expected store doesn't exist, copy the default store.
       NSFileManager *fileManager = [NSFileManager defaultManager];
       if (![fileManager fileExistsAtPath:[storeURL path]]) {
           NSURL *defaultStoreURL = [NSURL fileURLWithPath:[[NSBundle 
           mainBundle] pathForResource:@"App_Name" ofType:@"sqlite"]];
   
           if (defaultStoreURL) {
               [fileManager copyItemAtURL:defaultStoreURL toURL:storeURL 
               error:NULL];
           }
   
       NSError *error = nil;
   
       // Options for migration
       NSDictionary *options = @{NSMigratePersistentStores
                               AutomaticallyOption: @(YES),
                          NSInferMappingModelAutomaticallyOption : @(YES) };
   
       //NSDictionary *options = @{ NSSQLitePragmasOption : 
                                 //@{@"journal_mode": @"DELETE"} };
   
       if (![_persistentStoreCoordinator addPersistentStoreWithType:
          NSSQLiteStoreType configuration:nil URL:storeURL options:
          options error:&error]) {
           // Handle error
       }
       return _persistentStoreCoordinator;
   }
   
   

I've also tried the below method, from the CoreDataBooks sample code, with no luck.

// If the expected store doesn't exist, copy the default store.    
NSFileManager *fileManager = [NSFileManager defaultManager];
if (![fileManager fileExistsAtPath:[storeURL path]]) {
        NSURL *defaultStoreURL = [[NSBundle mainBundle] URLForResource:
                                 @"CoreDataBooks" withExtension:@"CDBStore"];

     if (defaultStoreURL) {
            [fileManager copyItemAtURL:defaultStoreURL toURL:storeURL 
            error:NULL];
        }
}

Also, I only want to populate the tableview with few lists. Is it better to create a flag for first launch, and populate with code?

I really don't know what I missed. Please help me with this. Your help will be appreciated. Thanks
