I keep getting weird constraint errors and the views in my cell don't show up, below are the cell class and error log.
My table view cell class
#import "TableViewCell.h"
@implementation TableViewCell
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
self.translatesAutoresizingMaskIntoConstraints = NO;
self.recipeImageView = [UIImageView new];
self.recipeImageView.image = [UIImage imageNamed:@"imagePickerBackground"];
self.recipeImageView.layer.cornerRadius = 20;
self.recipeImageView.layer.borderColor = [[UIColor blackColor]CGColor];
self.recipeImageView.layer.borderWidth = 1;
self.recipeImageView.layer.masksToBounds = YES;
[self addSubview:self.recipeImageView];
self.descriptionLabel = [UILabel new];
self.descriptionLabel.text = @"description";
self.descriptionLabel.font = [UIFont fontWithName:@"Chalkduster" size:12];
self.descriptionLabel.textColor = [UIColor blackColor];
self.descriptionLabel.layer.cornerRadius = 20;
self.descriptionLabel.layer.borderWidth = 1;
self.descriptionLabel.layer.masksToBounds = YES;
self.descriptionLabel.layer.borderColor = [[UIColor blackColor]CGColor];
[self addSubview:self.descriptionLabel];
NSDictionary *viewsDictionary = NSDictionaryOfVariableBindings(_descriptionLabel, _recipeImageView);

// NSArray *constraintsTwo = [NSLayoutConstraint constraintsWithVisualFormat:@"V:|-10-[_recipeImageView]-10-|" options:0 metrics:nil views:viewsDictionary];
NSLayoutConstraint *equalConstraint = [NSLayoutConstraint constraintWithItem:self.descriptionLabel attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:self.recipeImageView attribute:NSLayoutAttributeWidth multiplier:1 constant:0];

[self addConstraints:constraints];
// [self addConstraints:constraintsTwo];
[self addConstraints:verticalConstrains];
[self addConstraint:equalConstraint];
}
return self;

here are the programatic registration methods in the view controller (datasource and delegate of the table view)
in view did load
- (void)viewDidLoad {
[super viewDidLoad];
self.tableView = [[UITableView alloc]initWithFrame:self.view.bounds style:UITableViewStyleGrouped];
self.tableView.delegate = self;
self.tableView.dataSource = self;
[self registerTableView:self.tableView];
[self.view addSubview:self.tableView];
[self.tableView reloadData];
[self setUpNavigationBar];
}
register method
- (void)registerTableView:(UITableView *)tableView {
[tableView registerClass:[TableViewCell class] forCellReuseIdentifier:@"cell"];
}
cell for row at index path
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

return cell;
}

return 300;
}
The error log (it doesn't crash so I can't put a breakpoint)
