Well whaddya know. I just got the same crash and the first result for googling NSISObjectiveLinearExpression setPriorityVector:forKnownAbsentVariable: is your gist. Small world.

Does someone find out the reason of this crash? I am experiencing same on a removeFromSuperview call and cannot figure out why :(

I encounter the same problem, and app crashed while rotate, it seem that layout is not right for me. Maybe you can find something like this ' internal error. Setting empty vector for variable UIView'.

I encounter this crash because I override updateConstraints of UITableViewCell

In case it helps anyone else, I was getting an Setting empty vector for variable error with use of a UIStackView where the spacing property was not set.

Not sure if it's the actual cause, or just a weird correlation, but setting spacing property to a non-zero value prevents this error for me.

In my case it was improper usage of dispatch queues. Make sure you're calling the UIView methods on the main queue.

This doesn't worked for me! i have set spacing to 1.0
