i have a crash on iOS from the wild which looks something like the following
Exception Type: SIGTRAP
Exception Codes: TRAP_BRKPT at 0xe7ffdefe
Crashed Thread: 0
Application Specific Information:
*** Terminating app due to uncaught exception '', reason: ''
Thread 0 Crashed:
0 MyApp 0x002bf4d8 0xdb000 + 1983704
1 MyApp 0x002bf4f4 0xdb000 + 1983732
2 MyApp 0x004e17ef 0xdb000 + 4220911
first question: I'm under the impression SIGTRAP is related to the debugger. how does this happen in production?
I am able to sylbolicate correctly, but not this TRAP_BRKPT at 0xe7ffdefe
I think knowing what lives at 0xe7ffdefe will help me figure out what's going on. so the the second question is how do i find out what is living at 0xe7ffdefe?
I've tried running
atos -l -arch armv7 -o ./MyApp 0xe7ffdefe
and got the output
0x00004014 (in MyApp)
0x0000400a (in MyApp)
Edit:
figured i might as well provide the symbolicated results
0 MyApp 0x000000010027c5d8 MyController.viewDidLoad() -> () (MyViewController.swift:26)
1 MyApp 0x000000010027c5f8 #objc MyViewController.viewDidLoad() -> () (MyViewController.swift:0)
where line 26 is self.webView.loadHTMLString(self.staticScreen.body, baseURL: nil)

Recently I submitted an app to appstore but I keep getting some error logs that I can't reproduce. I tried many times on simulator and device with the same ios version but no result. The error log is like below:

How can I find what causes the crash?
I'm trying to upload my app that uses ARKit (Unity build) to iTunes Connect for TestFlight distribution. While both exporting and uploading to app store processes from Xcode -> Organizer I see crash on "Stripping extended attributes for APPNAME.app".
I checked all configuration of bitcode and symbols on/off, signing automatically, manually. Deployment target of my project is iOS 10, as 11 cannot be set.
I also tried following steps from simillar thread (https://forums.developer.apple.com/thread/83219) and added App Store 1024 icon to Images.xcassets.
Any ideas why Xcode is crashing?

I've had to uncheck all checkboxes and use manual managing signing, then it was possible to proceed in the wizard.
Does the xattr command line tool work? It's possible your python installation is damaged, or if you've replaced the installed xattr module then you may need to reinstall the system provided one.
I had been experiencing same frustating problem and it happen almost all day , Xcode 9 suddenly crashes in the middle of the archiving process, resulting in the same error report.
#dangercheng gave me insight about archive process in xcode 9, which is, it needs the xattr command , therefore I go check xattr command in my macbook and somehow xattr doesn't work. From the verbose message, it reveals that the error is related to file permission owned by folders/files inside /Library/Python/2.7 . Somehow a user other than root has no right to write (w/ 2) on those files/folders.
From above facts I concluded that I need to change file permission in this case chmod -R 775 and apply it to all folders and its content on /Library/Python/2.7. After that my xattr is running well and my Archive process in Xcode 9 is running smoothly, experiencing no crash.
Thanks for all of you guys
In my case, it was due to permissions issues with python.
When running xattr from terminal I had the following error:
IOError: [Errno 13] Permission denied: '/Users/cb/Library/Python/2.7/lib/python/site-packages/zc.buildout-1.5.2-py2.7.egg-info/namespace_packages.txt'
Taking a look inside the /Users/cb/Library folder I found that all of the folders were owned by cb:staff (my currently logged in user and group) but the /Users/cb/Library/Python folder was owned by root:wheel
Running the following will eliminate the error:
sudo chown -R $USER:$(id -g) /Users/$USER/Library/Python
After the sudo chown you can run xattr again to verify. There should be no errors or other output from the xattr command.
Probably not your fault but do file a bug with Apple. But when the Xcode uploader fails for any reason try the good ol' Application Loader:
Xcode.app/Contents/Applications/Application Loader.app
run 'xattr' command in mac terminal，if result like bellow：
python version 2.7.10 can't run /usr/bin/xattr. Try the alternative(s):
/usr/bin/xattr-2.6 (uses python 2.6)
/usr/bin/xattr-2.7 (uses python 2.7)
Run "man python" for more information about multiple version support in
Mac OS X.
you should creat a new soft link to '/usr/bin/xattr-2.7'
run bellow commands:
cd /usr/bin
sudo rm xattr
sudo ln -s xattr-2.7 xattr
this solve my problem!
I solved my problem following #dangercheng's answer.
I upgraded my python to python 3.6 two days ago.And it seems that the xattr command was executed under python3.6 .
However, when I execute xattr in terminal.
File "/usr/bin/xattr", line 31
continue
^
TabError: inconsistent use of tabs and spaces in indentation
Something bad happened!
So I edit the source code of xattr.
for i in g:
vers = vpat.search(i)
if vers is None:
continue //add 4 space
sys.stderr.write("%s (uses python %s)\n" % (i, i[vers.start():vers.end()]))
n = 1
```
python version 3.6.3 can't run /usr/bin/xattr. Try the alternative(s):
(Error: no alternatives found)
Run "man python" for more information about multiple version support in
Mac OS X.
```
another error!
I guess the xattr command should judge the version of python and execute suitable codes and the code of python3 contains some error.
Finally I change the default version of python to python2.7 and replace softlink of xattr to xattr-2.7. It works.
Attention, when xcodebuild execute xattr command the path of python was "/usr/bin/python".
The path "/usr/bin/python" was softlink too.
So, I resolved this problem following this step.
Step1:
cd /usr/bin
Step2:
sudo rm python
sudo ln -s python2.7 python
Step3:
sudo rm xattr
sudo ln -s xattr-2.7 xattr
If you can not found python2.7 under "/usr/bin", please find another suitable python path such as "/Library/Frameworks/Python.framework/Versions/2.7" etc.
I'm using Ionic to build a hybrid mobile app. Previously I've had no trouble launching the emulator via "ionic emulate ios" command. But all of a sudden the command started throwing errors.
I've tried removing then adding back the ios platform, uninstalling then re-installing ios-sim, but still get the same error message below. Any help would be much appreciated, thanks

What version of ios-sim are you using? (Run ios-sim --version to find out.)
The containsString crash on Mavericks is caused by this bug, which exists in v3.2.0 (see here).
If you downgrade to v3.1.1, or upgrade to v4.1.1, then ios-sim should work fine on Mavericks.
I updated Xcode. Not sure if that's the problem but it is where the problem started.
But long story short:
-"$ cordova emulate android" works
-"$ cordova emulate ios" does not work
It gives me (this is the last part of the output):

However, I can run the simulator fine from Xcode itself.
I have no clue what to do, I hope someone can help.
For Xcode 6 you'll need version 3 of ios-sim. Check your version by running ios-sim --version. Upgrade by running sudo npm update ios-sim -g.

Thanks for your help.
Try sudo rm /tmp/instruments_sock -- this is the socket file created by instruments.js to communicate with instruments. That file is probably not deleateable for some reason.
That command will delete the file. Alternatively try to change the permission settings for the file.
I also encounter this issue on Xcode 5.0.1, instruments doesn't work even start from UI
but instruments works fine with Xcode 5.0
After some investigation, I found that when instruments is starting, the scriptAgent in iPhoneSimulator SDK crashes.

So I replaced iPhoneSimulator7.0.sdk with the one in Xcode 5.0, then this issue is solved.
But I am not sure whether this replacement has any side effect.
