    <p>I keep getting the error "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[MainViewController minimalFormInContext:]: unrecognized selector sent to class" from this line of code: NSLog(@"Accessing specific mine entities");</p> <pre><code>NSEntityDescription *entity = [NSEntityDescription entityForName:@"Mine" inManagedObjectContext:managedObjectContext]; NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease]; NSError *error = nil; [request setEntity:entity]; NSPredicate *predicate; NSPredicate *metalFilter; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSString *region = [defaults stringForKey:@"mineArray"]; if([region isEqualToString:@"Butte &amp; Plumas"]) { predicate = [NSPredicate predicateWithFormat:@"(county Contains %@) OR (county Contains %@)",@"Butte",@"Plumas"]; } else if([region isEqualToString:@"Sutter, Yuba, &amp; Sierra"]) { predicate = [NSPredicate predicateWithFormat:@"(county Contains %@) OR (county Contains %@) OR (county Contains %@)",@"Sutter",@"Yuba",@"Sierra"]; } else if([region isEqualToString:@"Nevada &amp; Placer"]) { predicate = [NSPredicate predicateWithFormat:@"(county Contains %@) OR (county Contains %@)",@"Nevada",@"Placer"]; } else if([region isEqualToString:@"Sacramento &amp; El Dorado"]) { predicate = [NSPredicate predicateWithFormat:@"(county Contains %@) OR (county Contains %@)",@"Sacramento",@"El Dorado"]; } else if([region isEqualToString:@"San Joaquin, Amador, &amp; Calaveras"]) { predicate = [NSPredicate predicateWithFormat:@"(county Contains %@) OR (county Contains %@) OR (county Contains%@)",@"San Joaquin",@"Amador", @"Calaveras"]; } else if([region isEqualToString:@"Tuolumne &amp; Stanislaus"]) { predicate = [NSPredicate predicateWithFormat:@"(county Contains %@) OR (county Contains %@)",@"Tuolumne",@"Stanislaus"]; } else if([region isEqualToString:@"Merced, Mariposa, &amp; Madera"]) { predicate = [NSPredicate predicateWithFormat:@"(county Contains %@) OR (county Contains %@) OR (county Contains %@)",@"Merced",@"Mariposa",@"Madera"]; } [request setPredicate:predicate]; mArray = [[NSMutableArray alloc] init]; mArray = [[managedObjectContext executeFetchRequest:request error:&amp;error] mutableCopy]; </code></pre> <p>using debugger, I have narrowed down the error as occurring in:</p> <pre><code>mArray = [[managedObjectContext executeFetchRequest:request error:&amp;error] mutableCopy]; </code></pre> <p>How do I fix this?</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).
