We are having a crash in Foundation, but we are unable to detect what could be the problem. We think that maybe an animation could trigger this problem.
Has anybody encounter this kind of crash? Here is the trace of the problem.

We are getting the crash "NSString quotedStringRepresentation" very often is the production build. I saw the answers that were given in the previous post, but they did not help me. Can someone please help? Here's the log:

Unfortunately I do not have access to this device iOS 9.2.1. in the simulator and my device is working fine iOS 10.2
A SIGSEGV is an error / signal caused by an invalid memory reference or a segmentation fault. Seems like the app is trying to access an array element out of bounds or trying to use too much memory.
The way to fix this issue is to find out what the exception may be by making it happen on another device (or simulator), or getting the full console logs from that device. An easy way to do this might be to set exception breakpoints to see where the original exception that triggered the SIGSEGV is located.
Im trying to find crash from following code / snippet.

go to "Breakpoint navigator" and click on "+" button on bottom-left and select "Add Exception Breakpoint...".
This kind of breakpoint capture all exception, so you can navigate on stack error on left side and figure out what happened.
I have an issue where a screen with autolayout that works great on iOS 8 - but crashes on iOS 7.
All subviews are configured in the XIB.
The error message is:
Terminating app due to uncaught exception 'NSGenericException', reason: 'Unable to install constraint on view.
Does the constraint reference something from outside the subtree of the view? That's illegal.
constraint:<NSLayoutConstraint:0x7ef80720 V:[UIImageView:0x7ef7fb40]-(0)-[UILabel:0x7ef802f0]> view:<UIView: 0x7ef7f1e0; frame = (0 0; 768 275); autoresize = RM+BM; layer = <CALayer: 0x7ef7f240>>'

)
What is the issue?
Turns out these two lines caused the crash:
self.ninjaStarImage.layer.removeFromSuperlayer()
self.view.layer.addSublayer(self.ninjaStarImage.layer)
Moving them to viewDidLayoutSubviews solved the problem
I get the next line on the crash log:
[NSConcreteMapTable assign:key:value:isNew:]
This crash happens on iOS 7, but not on iOS 8.
Somewhere before this line there are calls for NSLayoutConstraint:
-[NSLayoutConstraint _addLoweredExpression:toEngine:integralizationAdjustment:lastLoweredConstantWasRounded:mutuallyExclusiveConstraints:]
-[NSLayoutConstraint _addToEngine:integralizationAdjustment:mutuallyExclusiveConstraints:]
-[NSLayoutConstraint _addToEngine:]
Do you guys think this crash has something to do with the Storyboard layout constraint I have set?

seems like your using iOS 8 only constraints go to the storyboard open it on the top left corner you will see a little yellow icon with reading mark on it press on it and search for iOS8 only warnings, if you find any remove those constraints and rebuild your application.
