     super.viewWillAppear(true) 
     self.collectionView.hidden = true

      Top(0).to((self.navigationController?.navigationBar)!, .Bottom) 
     ] 
    } 

Und es ist zu bewegen gib mir diesen Fehler.

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:0x14c06f370 UIImageView:0x14c1c2d30.width == 40>", 
    "<NSLayoutConstraint:0x14c1e5ff0 UIImageView:0x14c1c2d30.width == 22>" 
) 

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x14c06f370 UIImageView:0x14c1c2d30.width == 40> 

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. 
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

Das Problem besteht darin, dass Sie versuchen, die Beziehung zwischen Elementen herzustellen, die nicht in derselben Ansicht enthalten sind. Stattdessen können Sie:

override func viewWillAppear(animated: Bool) { 
    super.viewWillAppear(true) 
    self.collectionView.hidden = true 
    self.tableView <- [ 
     Top(0).to(self.topLayoutGuide)) 
    ] 
}
