Auto-Layout Constraints showing unexpected behavior

[cre8ivepark]

I am experiencing unexpected behavior of Auto-Layout Constraints on several places. All of them are added programmatically. Works well on Xcode but shows weird behavior on VS.
Adding some screen shots of Xcode and VS. Please take a look at the spacings marked with red block.

Example of Auto-Layout Constraints for UITableView & UIScrollView:

[tvList setTranslatesAutoresizingMaskIntoConstraints : NO];
[self.view addConstraints : [NSLayoutConstraint constraintsWithVisualFormat : @"H:|-0-[tvList(250)]" options : NSLayoutFormatDirectionLeadingToTrailing metrics : nil views : NSDictionaryOfVariableBindings(tvList)]];
[self.view addConstraints : [NSLayoutConstraint constraintsWithVisualFormat : @"V:|-0-[tvList]-0-|" options : NSLayoutFormatDirectionLeadingToTrailing metrics : nil views : NSDictionaryOfVariableBindings(tvList)]];

[svContent setTranslatesAutoresizingMaskIntoConstraints : NO];
[self.view addConstraints : [NSLayoutConstraint constraintsWithVisualFormat : @"H:[tvList(250)]-0-[svContent]-0-|" options : NSLayoutFormatDirectionLeadingToTrailing metrics : nil views : NSDictionaryOfVariableBindings(tvList, svContent)]];
[self.view addConstraints : [NSLayoutConstraint constraintsWithVisualFormat : @"V:|-0-[svContent]-0-|" options : NSLayoutFormatDirectionLeadingToTrailing metrics : nil views : NSDictionaryOfVariableBindings(svContent)]];

Below example uses Auto-Layout Constraints inside the UICollectionViewCell, for the UILabel element:

    label = [[UILabel alloc] initWithFrame:CGRectMake(0,0,150,250)];
    label.textAlignment = UITextAlignmentCenter;
    [self.contentView addSubview:label];
    label.font = [UIFont systemFontOfSize:120];
    label.clipsToBounds = NO;
    label.adjustsFontSizeToFitWidth = YES;
    self.contentView.clipsToBounds = NO;

    [self.contentView setBackgroundColor:[UIColor lightGrayColor]];
    [label setBackgroundColor:[UIColor yellowColor]];
    [label setTranslatesAutoresizingMaskIntoConstraints : NO];
    [self.contentView addConstraints : [NSLayoutConstraint constraintsWithVisualFormat : @"H:|-[label]-|" options : NO metrics : nil views : NSDictionaryOfVariableBindings(label)]];
    [self.contentView addConstraints : [NSLayoutConstraint constraintsWithVisualFormat : @"V:|-[label]-|" options : NO metrics : nil views : NSDictionaryOfVariableBindings(label)]];
