Why does the UIScrollView calculate a massive contentSize with AutoLayout?

So I've followed all the best practices with respect to having a scrollable content view that works with autolayout (first have one direct subview of UIScrollView, add all the pin constraints, etc), especially when you have a UITextView (i.e. disable scrollingEnabled on the text view)

for example here, or just googling UIScrollView and Autolayout you'll find a lot of tutorials that rehash the same thing.

I've done all this, but am noticing that the scrollView is calculating a contentSize that does not match the contentView's height. I have no idea why this is:

I expect moderators to point out other questions. I looked around and nothing really matched what I'm seeing...

You say it doesn't match, so... What is the contentView's height? And, is your contentView's bottom anchor constrained to the bottom anchor of the scroll view, with a constant of Zero? – DonMag
ha! very bizarre. Somehow in the storyboard the constant was set to 680 – horseshoe7

For completeness, it was DonMag's comment that solved it. Unknowingly, the constant was not set to 0, which explains why the contentSize.height WAS 680pt larger than the content.
