Autolayout Warning : Will attempt to recover by breaking constraint <NSLayoutConstraint in CollectionView
I'm using UICollectionView & Flow Layout and Class for layout of collectionView Cell is as to achieve slide animation like feedly app Or insorts app
import UIKit

Xib Design Looks like
ided into 5 parts
and each small view is assigned as SmallStory Class
and Story Board Looks Like
When I run App There is Autolayout warnings as below

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.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

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.

Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x174285e60 UIImageView:0x113d2c980.bottom == UIView:0x113d2d090.bottomMargin (active)>
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.
2017-06-06 22:18:04.070615+0530 Jansatta[1096:258239] [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.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
