Misplaced view warning and odd behavior with IB_DESIGNABLE custom view using auto layout

Question

I create a custom IB-designable view (see code below) which renders correctly in IB and also works fine when running it. However, in get this warning about the view being misplaced and I cannot manually resize the view in Interface Builder (when touching a resize handle, the view will jump around in its container).

I get the same or similar behavior for all kinds of different layouts. Do you have an idea if I'm doing something wrong here, or is this just a bug in IB?

(PS: I cannot just ignore the warning)

EDIT: added screenshot of constraints:

Here is the code (header):

    IB_DESIGNABLE
    @interface AKATestView : UIView
    @end

Implementation:

    @interface AKATestView()

    @property(nonatomic)BOOL subviewsCreated;
    @property(nonatomic)BOOL subviewConstraintsCreated;
    @property(nonatomic)NSDictionary* views;

    @end

Try removing self.translatesAutoresizingMaskIntoConstraints = NO; in your createSubviews method. IB seems to be relying on this translation to come up with correct measurement on the designer. I had the exact same problem and this fixed it.

I still have translatesAutosizingMaskIntoConstraints to NO for subviews. I confirmed that there aren't any extra constraints generated even with this set to YES. Hope it's the case for you too!
