    <p>Basically you got all your memory management wrong.</p> <p>First of all, allocating an object and putting it to a local variable will make the object disappear after the method ends. So after the end of your</p> <pre><code>- (void)viewDidLoad </code></pre> <p>method your </p> <pre><code>KBDataInitializer *data = ... </code></pre> <p>is already out of scope again. Together with it, the </p> <pre><code>@property (strong, nonatomic) NSManagedObjectContext *dataContext; </code></pre> <p>is gone.</p> <p>Second, the songs are </p> <pre><code>@interface KBSong : NSManagedObject </code></pre> <p>which makes them dependent on their NSManagedObjectContext.</p> <p>These are the basics, the short way to fix your current problem is:</p> <p>KBHomeController.h:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @class KBDataInitializer; @interface KBHomeController : UIViewController&lt;UITableViewDataSource,UITableViewDelegate&gt; { NSArray *songs; } @property (nonatomic, strong) KBDataInitializer *data; @end </code></pre> <p>KBHomeController.m:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view from its nib. self.data = [[KBDataInitializer alloc]init]; //Use for import updated new Songs [self.data importData]; songs = [self.data getAllSongs]; ... } </code></pre> <p>But this only helps with your current problem.

And also try to understand it.</p> <p>Also please note I would use a <a href="https://developer.apple.com/library/ios/documentation/CoreData/Reference/NSFetchedResultsController_Class/Reference/Reference.html" rel="nofollow">NSFetchedResultsController</a> for that task. </p>

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).
