Error while saving object in coredata - ios

Question

Here is my code:
- (IBAction) saveData
{
NSLog(#"saveData");
[self dismissKeyboard];
Fugitive *job = (Fugitive *)[NSEntityDescription insertNewObjectForEntityForName:#"Fugitive" inManagedObjectContext:managedObjectContext];
job.name = txtName.text;
NSError *error;
// here's where the actual save happens, and if it doesn't we print something out to the console
if (![managedObjectContext save:&error])
{
NSLog(#"Problem saving: %#", [error localizedDescription]);
}
// **** log objects currently in database ****
// create fetch object, this object fetch's the objects out of the database
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"Fugitive" inManagedObjectContext:managedObjectContext];
[fetchRequest setEntity:entity];
NSArray *fetchedObjects = [managedObjectContext executeFetchRequest:fetchRequest error:&error];
NSURL *storeURL = [[NSBundle mainBundle] URLForResource:#"iBountyHunter" withExtension:#"momd"];
id globalStore = [[managedObjectContext persistentStoreCoordinator] persistentStoreForURL:storeURL];
[managedObjectContext assignObject:job toPersistentStore:globalStore];
for (NSManagedObject *info in fetchedObjects)
{
NSLog(#"Job Name: %#", [info valueForKey:#"name"]);
}
[fetchRequest release];
[self.navigationController dismissModalViewControllerAnimated:YES];
}
In the console I get this error: Problem saving: The operation couldn’t be completed. (Cocoa error 1570.)
The new object is created in the tableview, but not saved thus when re-launching the app, the object disappears
