Interacting with a stackView created in Storyboard in code crashes

[m-levi]

I have an OAStackView that I created in my storyboard. In storyboard, I set the class to OAStackView, and set its constraints. I made an IBOutlet to this stackView in my code. In my code, when I try to edit any attributes of the stackView, like the distribution, or adding another view, the app crashes and gives me the following error:

-[UIView setDistribution:]: unrecognized selector sent to instance 0x155d6500

Not really sure what I'm doing wrong, any help would be greatly appreciated, Thanks!!

Try to delete Module at Custom Class for OAStackView in InterfaceBuilder.
