UITextView stretches horizontally but not vertically inside UIScrollView

My task is very simple - just display vertically scrolling text inside custom UIView. I have an UIScrollView with some container with one UITextView in it. Container is needed to add more items later. I use IB(xib file) to add autolayout constraints like shown below:

But everything I see is:

Simulator

And it's scrolling horizontally :-(

I've tried setting contentSize of UIScrollView:

Thanks a lot!

Edit: Text View's and Container View's intristic size are set to "placeholder". I understand that I should limit width of ContainerView, but it should work with all screen sizes and orientations, so setting width in code, IMO, worse than setting constraints.

Yeah! I've found the solution!

If someone facing the same problem:

You should add left and right constraints not to UIScrollView, but to superview of UIScrollView (to super-super-view).

Unfortunately, this cannot be done in IB, but you can do it within code:

[self addConstraint:[NSLayoutConstraint constraintWithItem:self.view 
    attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationEqual
    toItem:self.containerView attribute:NSLayoutAttributeLeft
    multiplier:1.0 constant:-30]];
[self addConstraint:[NSLayoutConstraint constraintWithItem:self.view
    attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual
    toItem:self.containerView attribute:NSLayoutAttributeRight
    multiplier:1.0 constant:30]];

Where self.containerView is view inside UIScrolllView and self.view is view outside UIScrollView

So:

You set vertical constraints to UIScrollView and horizontal constraints to top-level view.
