Delete confirmation alert is breaking constraints

I am following the instructions to implement a delete item functionality and then a delete confirmation alert. Everything works great (and looks fine too when I run the app), but xcode logs warning messages that some constraints cannot be satisfied. Why is that?

**2019-06-05 16:57:14.239004+0200 Homepwner[77897:9163488] [LayoutConstraints] Unable to simultaneously satisfy constraints.**

**Probably at least one of the constraints in the following list is one you don't want.** 

**Try this:** 

**(1) look at each constraint and try to figure out which you don't expect;** 

**(2) find the code that added the unwanted constraint or constraints and fix it.** 


**"<NSLayoutConstraint:0x600000d6fbb0 UIView:0x7f9ee6f29da0.width == - 16 (active)>"**


**Will attempt to recover by breaking constraint** 

**<NSLayoutConstraint:0x600000d6fbb0 UIView:0x7f9ee6f29da0.width == - 16 (active)>**

**Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.**

**The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.**
