I have been developing iOS applications for about 2 years and have never come across this before.
I recently took on a project, but for some reason whenever it crashes while I am debugging the console shows no details about the error. The code highlights with a SIGABRT or ESC_BAD_ACCESS but never tells me the details of the crash in the console (like unrecognised selector sent to instance etc.)
I've come to the conclusion this is a problem with the project settings as I test other apps with the same xCode and don't have the same problem.
I've looked all over but can't find anyone with a similar problem please help!
Try adding an Exception breakpoint:
Open the breakpoint navigator and click the + icon and add an exception breakpoint
Add a breakpoint with the settings as shown
I don't think this is an Xcode problem. But try this two options:
1) In your VC or AppDelegate perform crash on purpose for example:
[self performSelector:#selector(methodNameNotExistingInMyProject:) withObject:nil];
This should return you some console output
2) Are you sure you have Debug configuration in scheme? You may want to check it out.

I'm having random crashes within my swift app and they are all throwing a similar error around CFDictionaryGetValue
Here are two screenshots from my Google Crashlytics showing the error and that its effecting to different URLs, Note these are from two separate crashes
Then here is also a screenshot directly from within Xcode where I was able to reproduct the error:
There doesn't seem to be any specific action that causes this issue and it occurs at random times.
And advise for trying to trace it and debug would be much appreciated!
Thanks

As it turns out this issue was caused by a bug within the Firebase Performance SDK. After removing the SDK everything is working as expected
https://github.com/firebase/firebase-ios-sdk/issues/6734?fbclid=IwAR0L5U4dsBjyUGmklr8qEohlKTyY7P6zJwzWUnU3dUTnFmb0aclK4-rt5os
Try setting up an Exception breakpoint, it would probably give you more information to help you debug it:
In Xcode:
Go to Breakpoint Navigator (CMD+8)
Click the + button in the bottom left corner of the navigator and then choose Exception Breakpoint...
Select All in the Exception field
Re-run your app and you should get clearer information in the debugger
My ios project builds and installs on the device but has a runtime crash after launcher screen finishes.
I'm looking in the debugger console but I don't see any logs to help me diagnose what is going on. My project was working correctly before I upgraded react-native-firebase from v3 to v4 https://github.com/invertase/react-native-firebase/releases. Stepping into or over the code doesn't show me any errors in the code itself.
I'm hesitant to log an issue with the react-native-firebase project before I understand what the error could be - and whether it was a simple error somewhere.
However, the error seems pretty cryptic and I don't have any clues on what's actually causing the runtime crash. Is there a way that I can read more verbose logs that might give more info on the crash?
add an Exception breakpoint: by going to the breakpoint tab (command + 8) and the click the add "+" button on the bottom left corner and click on Exception breakpoint - all exceptions.
That will pause the code exactly were the exception is being raced therefore you will be able to see the line of code that it is causing the crash.
i need your help i've got this frustrating "random" error.
The app is compose of one Mapviewcontroller and a collectionview on the second controller.
Sometimes when I return to the map from the second controller the app suddenly crash with this error on the the "trap" line.
The crash report doesn't point to any of my lines of code.
EXC_BREAKPOINT (code=EXC_ARM_BREAKPOINT, subcode=0xdefe)
I said "random error" because the same version of the same app could be build and run smooth for days, then suddenly it stuck. The only way to regain control of the app is to delete manually from the iPad and rebuild.
For your information the app uses Coredata.
Any ideas? Some method to figure out where the error come from?
Any help is appreciated, thanks!
I had this error on line like that
NSLog(#"%#: tutorial view retain count = %ld",self.class,CFGetRetainCount(CFTypeRef(tutorialView)));
where tutorialView equals nil
Restart your iOS device - that worked for me. You can also try restarting Xcode.
I was getting the crash where I had a breakpoint set, but I had breakpoints turned off. I think that there are glitches in how Xcode handles breakpoints that can cause this issue even if there aren't issues in the code itself.
I am working on to-do list app for iOS. when i build the run the app on my system which i used to development, there are no problems. However when i xcode project on another system.
I get the following error and the app crashes on launch.
Any inputs on what is going wrong?
Thread 1: EXC_BREAKPOINT(code = EXC_I386_BPT, subcode=0x0
I've experienced this while using a breakpoint which would log something and then continue automatically. Disabled that, and things returned to normal. As the message suggests, it's a breakpoint issue
I've been testing AppCode and I can't seem to find any information as to WHY an app is crashing.
I've added an exception breakpoint and I can see the line of code causing the crash but no info on why.
In Xcode the exception reason is printed into the console but in AppCode I just get "Exception = Exception Breakpoint".
Can someone point me in the direction of getting useful information out of the crash.
AppCode, Choses Run, View Break points settings, Click on "Log message to console" by default it is off.
Command liners use, shift-fn-command-f8
AppCode also prints the exception in the console, providing that you launch the app in debug mode (as, actually, the debugger does it).
