I first tried disabled the scroll bar by setting:
scrollView!.hasHorizontalScroller = false
and that successfully worked, but I could still scroll from left to right by using my trackpad.
Is there a way to ensure that horizontal scrolling is completely disabled for an NSScrollView object?
var scrollView = UIScrollView(frame:myFrame) let scroll = CGSizeMake(myHeight, myFrame.size.width) scrollView.contentSize = scroll
Fixes the frame width to prevent horizontal scrolling.
Even with a correct content size, I was still able to use two-finger gestures to scroll horizontally a bit before it snaps back into place. To fix this, you can set the elasticity:
scrollView.horizontalScrollElasticity = .None
