Programmatically created NSTableView within NSScroll view cannot scroll horizontally

I am on macOS 10.16 (BigSur) XCode 12, objective-c.

I have create a NSTableView within an NSScroll View programmatically and filled it with dummy data. I CAN scroll down while i CANNOT scroll left and right. So i assume there's some misconfiguration in the code but i can't figure it out.

Here's the behaviour -as you can see theres more content on the right, but scrollbar doesn't scroll:

And here's the code:

NSEdgeInsets insets = NSEdgeInsetsMake (0,0,0,0); // This is usually dynamic, just for demo purposes
NSEdgeInsets margins = NSEdgeInsetsMake (0,0,0,0); // This is usually dynamic, just for demo purposes

// Create tableView
NSTableView* tableView = [[NSTableView alloc] initWithFrame:NSZeroRect];
tableView.translatesAutoresizingMaskIntoConstraints = NO;
tableView.backgroundColor = [NSColor clearColor];
tableView.delegate = self.delegate ? self.delegate : weakSelf;
tableView.dataSource = self.delegate ? self.delegate : weakSelf;
tableView.rowHeight = [SHDataTableCellView height];
tableView.intercellSpacing = NSMakeSize(2, 2);
tableView.headerView = [[NSTableHeaderView alloc] initWithFrame:NSMakeRect(0, 0, 0, CGFLOAT_MIN)];
if (@available(macOS 11.0, *)) {tableView.style = NSTableViewStylePlain;}
self.tableView = tableView;

// Create Scroll View
NSScrollView* scrollView = [[NSScrollView alloc] initWithFrame:NSZeroRect];

// Setup scrollView
scrollView.drawsBackground = NO;
scrollView.hasVerticalScroller = YES;
scrollView.hasHorizontalScroller = YES;
scrollView.autohidesScrollers = NO;
scrollView.translatesAutoresizingMaskIntoConstraints = NO;
scrollView.documentView = tableView;    
scrollView.scrollerStyle = NSScrollerKnobStyleDefault;
scrollView.automaticallyAdjustsContentInsets = NO;
scrollView.contentInsets = insets;
scrollView.scrollerInsets = NSEdgeInsetsMake(-(insets.top), -(insets.left), -(insets.bottom), -(insets.right));    
self.scrollView = scrollView;

[self.view addSubview:scrollView];

// Add constraints
NSDictionary *viewBindings = NSDictionaryOfVariableBindings(view,scrollView);
NSDictionary *metrics = @{ @"marginLeft" : @(margins.left),
                           @"marginRight" : @(margins.right),
                           @"marginBottom" : @(margins.bottom),
                           @"marginTop" : @(margins.top),
                           @"insetLeft" : @(insets.left),
                           @"insetRight" : @(insets.right),
                           @"insetBottom" : @(insets.bottom),
                           @"insetTop" : @(insets.top)};

[view addConstraints: [NSLayoutConstraint constraintsWithVisualFormat:@"H:|-(marginLeft)-[scrollView]-(marginRight)-|" options:0 metrics:metrics views:viewBindings]];
[view addConstraints: [NSLayoutConstraint constraintsWithVisualFormat:@"V:|-(marginTop)-[scrollView]-(marginBottom)-|" options:0 metrics:metrics views:viewBindings]];

[scrollView addConstraint:[NSLayoutConstraint constraintWithItem:self.tableView
                                                 attribute:NSLayoutAttributeWidth
                                                 relatedBy:NSLayoutRelationEqual
                                                    toItem:scrollView
                                                 attribute:NSLayoutAttributeWidth
                                                multiplier:1.0
                                                  constant:0]];

[scrollView addConstraint:[NSLayoutConstraint constraintWithItem:scrollView
                                                 attribute:NSLayoutAttributeHeight
                                                 relatedBy:NSLayoutRelationEqual
                                                    toItem:nil
                                                 attribute:NSLayoutAttributeNotAnAttribute
                                                multiplier:1.0
                                                  constant:60]]; // equals 2 rows of content

NSEdgeInsets margin and insets are set to 0 in this example are tend to be used as dynamic variables (you may ignore them)

Removed the width constraint and it worked. Sometimes its just too obvious and you still don't see it.
