I've been using Autolayout with NSScrollView. Basically to answer your
question, you need to set the constraints on the NSClipView inside the
NSScrollView
NSClipView *clipView = [_scrollView contentView];
NSDictionary *viewsDict = @{@"childView": _childView};
[clipView addConstraints:[NSLayoutConstraint
constraintsWithVisualFormat:@"H:|[childView]|"
options:0 metrics:nil views:viewsDict];
Otherwise the NSClipView will give your view a width of 0. This is assuming
your view has overriden -(NSSize)intrinsicContentSize to return
NSViewNoIntrinsicMetric for the width
Hope that helps slightly. I've been finding Autolayout pretty good once you
get your head around it and taking all the hassle out of recalculating
layout frames
