Visible SQLite file but invisible data in iOS simulator

i've created an app that uses Core-data. Now i want to see the data that i've stored in various entities in that app. App has been installed in iOS-simulator (7.0.3)

This did not help

ScreenShot:Table schema

Here is the Empty table

And here is how I am saving the data..

EffController *newController = [NSEntityDescription insertNewObjectForEntityForName:@"EffController" inManagedObjectContext:self.managedObjectContext];
    newController.name=@"fgfghjfghj";
    newController.uniqueUID= @"ffghfg";
    newController.parentOutputID = @0;
    newController.localIP=@"***.***.***.***";
    newController.localPort= @XXXX;

    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc]
                                    initWithEntityName:@"EffControllerType"];
    NSError *requestError = nil;
    /* And execute the fetch request on the context */
    NSArray *types = [self.managedObjectContext executeFetchRequest:fetchRequest error:&requestError];

    for (EffControllerType *type in types) {
        if ([type.name isEqualToString:@"***********"]) {
            newController.type= type;
            break;
        }
    }
    NSError *error = nil;
    if (![newController.managedObjectContext save:&error]) { //here is the mistake.
    //It should be self.managedobjectContext    
        NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
        abort();
    }

Edit
After long discussion with @HaniIbrahim problem was solved… But still not clear about why the content was visible in app, not in sqlite file? & why context for managed object? Can anybody help to find real issue behind the topic?

After you insert, update or delete anything in CoreData you have to save context to actual apply your updates

NSError *error = nil;
[context save:&error]; // context is your managedObjectContext that you use to communicate with coreData

Edit

After you post your code I found that you are using two context self.managedObjectContext and newController.managedObjectContext ?

You can view the data by using SQLite Manager plugin for Firefox. Open firefox -> Install the plugin -> Open the plugin -> navigate to the below path using Open File option 

Library/Application Support/iPhone Simulator/VERSION_OF_YOUR_SIMULATOR/Applications/YOUR_PROJECT(Usually in alphanumeric)/YOUR_DB_FILE.sqlite

That should do.

There are number of plugins and applications available similar to SQLite Manager. You may choose that as per your desire.
