What triggered this SIEGSEGV Exception type - ios

The iOS app I am developing is having this crash with many of my users (I can catch it via PLCrashReporter library). The Exception type is SIGSEGV, so I believe is an error involving memory (like acceding a deallocated variable?).
But how can I discover what triggered it? The first line in the stacktrace involving my app is line 13:
13 ****** 0x004a9b40 _mh_execute_header +
And I really can't catch what this could mean.
Is there a way to see more info, or maybe the first four/five lines can help me more than I think?
Additional information: I use massively CoreData and NSManagedObjects, so I can't check every instance if those.

How to initialize a CLLocationCoordinate2D struct [duplicate]

This question already has answers here:
CLLocationCoordinate2D can't be instantiated
(2 answers)
Closed 1 year ago.
I'm trying to initialize a CLLocationCoordinate2D from a Swift Playground, and I'm getting the error:
error: Execution was interrupted, reason: signal SIGABRT.
The process has been left at the point where it was interrupted, use "thread return -x" to return to the state before expression evaluation.
Not sure what I'm doing wrong. Here is what I tried:
var temporaryCoordinate = CLLocationCoordinate2D(latitude: 0.0, longitude: 0.0)
You have found a very unusual and interesting bug. I can reproduce your problem by running the following code in a Blank iOS playground:
import UIKit
import CoreLocation
var temporaryCoordinate = CLLocationCoordinate2D(latitude: 0.0, longitude: 0.0)
What is going wrong is that the runtime environment, the Playground, is itself crashing. In the Mac, in the Console app, with Crash Reports left tab, we can see that the Xcode Playground is crashing.

I think the problem is that there are two Core Location binaries in play:
0x18321e000 - 0x1832a8fff com.apple.corelocation (2420.12.16 - 2420.12.16) <F94D1F57-86D5-3A82-8F2B-80A9AEAC0308> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/CoreLocation.framework/CoreLocation
and
0x1b1f96000 - 0x1b1f98fff +libswiftCoreLocation.dylib (5) <EE615605-C11D-3F60-B611-8B1C1D45FEEA> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/swift/libswiftCoreLocation.dylib
and the playground is communicating from one world to the other world; talking to the iOS simulator. But there is an incompatibility between the two as the message is not carried across correctly due to type confusion. This leads to the
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSValue
valueWithMKCoordinate:]: unrecognized selector sent to class
0x1c9d3f588' terminating with uncaught exception of type NSException
I think you should file a bug with Apple. To avoid the problem, write your code based on the iOS Simulator directly, instead of using the Playground. In such circumstances, your code will execute correctly (since it directly will run against the simulator without the intervening bridge from the Playground).
As Alexander says in his comment, there is nothing wrong with the code you posted. The cause of the crash is elsewhere.

Unable to edit storyboard in Xcode 12 after IBAgent NSInternalInconsistencyException: Failed to create work interval

I am unable to edit storyboard files in my xcode project.
I have tried cleaning my Derived Data and cleaning my project but it has had no effect.
In the IBAgent crash log I found this.
I get further errors in the designer "already shutdown" errors. I believe because of the IBAgent crash
Here is the crash log:

This happened when I upgraded to Xcode 13.0.
I couldn't find much help on the subject, but from trial and error, the solution for my situation seemed to be:
open ~/Library/Developer/Xcode/iOS\ DeviceSupport
rm -rf <VERSION>
I did this for every version expect the latest version (in this case 15.0.2 (19A404))

My app workes fin in my device but crash in Apple test couldn't find the reason

I tested my iOS app thoroughly in my device and there ware no crash but when I submitted the app for release it crashes repeatedly. I tried to analyze I couldn't find the reason. When I look the creash log it looks crash happens in

How do I debug this crash in UIDictationController?

Recently I am trying to debug with the information provided by Crash Reports. So far I have been able to identify and fix some bugs but not this one.
As I read from the crash report, it's something wrong with UIDictationController, but my code did not call UIDictationController at all. The crash report is generated by PLCrashReporter.
It seems that the user is using an iPad Mini (WiFi) and running iOS 6.0.2.

Is there any way that I can do with this bug? Or, at least mitigating the issue? Thanks in advance.
the problem is that somewhere in your app you have a keyboard come up and with iOS version 6.0.1 and 6.0.2, apple enabled the dictation controller even if you didn't specify it to be enabled. Two solutions to fixing it: create a custom keyboard without it or implement dictation in your app.
My suggestion is to just let it be, only affects two outdate iOS versions and hopefully the crashes will go away as the users upgrade their devices
I have the keyboard coming up for a custom TextView, and when the user pushed the dictation button, said something, pushed finish, and then they tried to dismiss the keyboard, there would be a crash. Possible this is also what you're experiencing?

I've pasted only thread 0 because it seems it is the one which crashed.
This is all new to me and I have no idea how to interpret this log and solve the problem.
I've tested my App on my iPhones 4 and 4s and on a 3GS of a friend of mine and we didn't see any crash.
Now I'm getting 1 star reviews from some people saying iPill is crashing a lot.
Any help will be really appreciated.
Thanks.
I'd say to start in your tables cellForRowAtIndexpath method.
I'd hazard a guess that there's an issue with your data model and it's calling data from an array that is empty.
Just from this crashlog it looks as if you're having an out-of-bounds problem triggered by line 314 of ProssimeDosi.m due to something requesting more data than is available.
See the accepted answer here for a more elaborate explanation: Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSMutableArray objectAtIndex:]: index 1 beyond bounds [0 .. 0]'
