Crash at line 240 of BFNavigationBarDrawer.m

Here are the logs.

I am calling the hideAnimated method from my view controller's viewWillDisappear. It is important to note that this crash doesn't happen most of the time.

Line 240 is [self.superview layoutIfNeeded]. Since you're calling hideAnimated in viewWillDisappear, confirm that when this line is executed you actually still have a superview.

I am pretty sure that a message sent to a nil object is treated as no-op in Objective-C. The problem's cause should lie elsewhere.

I can't reproduce this. Could you maybe post your view controller's code in a gist, or at least the relevant parts? Thank you.

I think that I know when this error occurs. It only takes place when view controller interactive swipe takes place. I have the same issue. I didn't manage to fix it.
