doesn't dequeue the cell with identifier that exists and is set

I set the identifier in in the storyboard file and my code is: 

@interface SLSpuriosCorrelationsTableViewController ()

@property (strong, nonatomic) SLDataSourceObject* dataSource;

@end

@implementation SLSpuriosCorrelationsTableViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    _dataSource = [[SLDataSourceObject alloc] initWithDefaultValues];
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return _dataSource.dataBankURLs[1].count;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    SLSpuriosCorrelationsTableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@"reuseableCustomCell" forIndexPath:indexPath];

    if (!cell) {
        cell = [[SLSpuriosCorrelationsTableViewCell alloc] initWithRow:indexPath.row];
    }

    return cell;
}

I was told that if the class and the identifier are set inside the main storyboard file registering is not needed.

the custom cell class:

@interface SLSpuriosCorrelationsTableViewCell ()

@property (weak, nonatomic) SLDataSourceObject* dataSource;

@end

@implementation SLSpuriosCorrelationsTableViewCell

- (SLSpuriosCorrelationsTableViewCell*)initWithRow:(NSUInteger)row {
    self = [super init];

    _row = row;
    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);
    dispatch_async(queue, ^{
        NSURL* imageURL = [[NSURL alloc] initWithString:[_dataSource.dataBankURLs[1] allValues][_row]];
        NSData* imageAsData = [[NSData alloc] initWithContentsOfURL:imageURL];
        UIImage* image = [[UIImage alloc] initWithData:imageAsData];
        dispatch_async(dispatch_get_main_queue(), ^{
            self.imageViews.image = image;
        });
    });

    return self;
}

but i still get right after dequeueReusableCellWithIdentifier is called

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'unable to dequeue a cell with identifier reuseableCustomCell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard'

You get that error, because you put SLSpuriosCorrelationsTableViewCell not in SLSpuriosCorrelationsTableViewController, but in SLSettingsTableViewController

try this

 - (void)viewDidLoad {
    [super viewDidLoad];

      [self.tableView registerNib:[UINib nibWithNibName:@"SLSpuriosCorrelationsTableViewCell" bundle:nil]
     forCellWithReuseIdentifier:@"reusableCustomCell"];
}

and call like 

 -(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

static NSString *CellIdentifier = @"reuseableCustomCell";

SLSpuriosCorrelationsTableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];


if(!cell)
{
    cell = [[SLSpuriosCorrelationsTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}

// Configure the cell...



cell.xxx.text = [yourarrayNam objectAtIndex:indexpath.row];

return cell;
}
