2020-01-28 22:09:56.581680-0500 Zenn[19786:13017249] [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.

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x600000122670 UIButton:0x7f92b3c10520'Button'.height == 30   (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.

Похоже, он больше не может удовлетворять требованию установки высоты кнопки равной 30. Но что с ней конфликтует?

Внимательно проверьте ваши ограничения и добавьте метод делегата для высоты tableViewCell.

Swift 5 

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableView.automaticDimension
}
...
