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'm dealing with a weird crash which I didn't find a solution yet for.
The title of the crash in Organizer is UIKit: __57-[UIView(AdditionalLayoutSupport) _switchToLayoutEngine:]_block_invoke_2 + 316 and the whole stacktrace is below.
I've checked the startController(_:) method from AppDelegate and everything seems to be fine. Is it a constraint issue maybe? What else could it be?

Thanks in advance!
I finally solved the problem. Shortly, the crash appeared only on iOS 10.x devices, because some of my .xib files had had set a later version of iOS (11.0 i.e.) in "File Inspector -> Interface Builder Document -> Builds for" instead of the default Deployment Target set in the project settings, which was 10.x of course.
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.

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.
I have this app in the app store, which according to Crashalitics, its %92-%95 stable. I made a similar app for Android and its around 98% stable. I am trying to get the stability up - but I don't see how. All the bugs I am seeing in the IOS version are not touching my code.
I see random bugs, that are not reproducible, and when they do are very random. Each happens 1-10 times, but I have a list of ... ~30 different items.
The app is pretty simple - a mostly linear storyboard (a few jumps, but no loops). The only project I am using which is not Apple's code is InAppSettingsKit, and most of the app is just maps which shows some items. The project is using ARC and currently compiled using XCode6 (but XCode5 showed the same symptoms).
How can I find these crashes? Is this in an inherent problem of IOS7-8? I do see some apps just closing up when I use the IPhone, and friends to tell me that IOS is not that stable, but ... I just think I am doing something wrong.
IOS8 70% IOS7 30%
