thanks Ishu, you helped me a lot by pointing the NSArray way!!!

this was the solution I ended up by enlightenment !

- (NSPersistentStoreCoordinator *)persistentStoreCoordinator {

if (persistentStoreCoordinator_ != nil) {
    return persistentStoreCoordinator_;
}



NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:@"ChildCare_v02.sqlite"];

NSString *storePath = [[NSBundle mainBundle] pathForResource:@"ChildCare_v02" ofType:@"sqlite"];


NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"ChildCare_v02.sqlite"]; //este es el que sirve!!! CREE ESTE

NSLog(@"store URL %@", storeURL);

    // Put down default db if it doesn't already exist
NSFileManager *fileManager = [NSFileManager defaultManager];
if (![fileManager fileExistsAtPath:writableDBPath]) {
    NSLog(@"proceda aqui");
    NSString *defaultStorePath = [[NSBundle mainBundle] pathForResource:@"ChildCare_v02" ofType:@"sqlite"];
    NSLog(@"no existe todavia");
    NSLog(@"defalultStorePath %@", defaultStorePath);


    if (defaultStorePath) {
      [fileManager copyItemAtPath:defaultStorePath toPath:writableDBPath error:NULL];
        NSLog(@"storePath= %@", storePath);
    }
}    

NSError *error = nil;
persistentStoreCoordinator_ = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]];
if (![persistentStoreCoordinator_ addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:nil error:&error]) {

NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
abort();
    }    

   return persistentStoreCoordinator_;
    }

hope it helps some noob like me wanting to import prepopulated sqlite to a coredata db, note that first need to create blank db, to keep the structure and then populated (I used SQLite database browser to import CSV columns to my sqlite)
