My app is crashing with an error code - Program exited with status value:255. I can't find any error or stack trace in console. This crash will occur only when the app is installed and executed for the first time. I don't get this error while running the app second time. I searched around the web and found a solution. According to that I changed the Target setting of "Compile for Thumb" to off. Even after I am getting this crash and error.
In my previous versions i don't get this error. I don't know whether any change in the code or settings of Xcode causing this problem.
Any help is highly appreciated.
Thanks,
Adarsh V C.

My app consistently crashes at the same location. Should be easy to fix as I could trace the issue down to the exact location. But there is no error message at all. No break occur in debugger. It just crashes completely and silently. No stack, no actual error. App closes and that is it. Tried in 1.13 and 1.17.
Lost connection to device.
Exited (sigterm)
Any idea how to tackle? How to find such error? It is on iOS.
For those who meet a similar issue. Seems native iOS codes won't throw exception. A plugin with a bug may crash your app straight.
Yesterday i was testing my app in the iOS simulator and everything was working fine. I then decided to run the app on my iPhone and i got the error unable to install application, Unknown error occurred this has happened before so I cleaned my build folder (as this has fixed this issue before) however, the same error occurred. I then ran the app in the iOS simulator again and now i get the error Unable to run app in Simulator, An error was encountered while running (Domain = LaunchServicesError, Code = 0). I find this very weird as i didn't change anything besides trying to run the app on my iPhone. I have tried every solution given on this post and still no luck.
I'm sorry if my question doesn't contain much detail but as I said I didn't change anything and it was building and running fine a minute before plugging in my iPhone and trying to run it on there.
Any help would be much appreciated.
edit
I tried running other projects (with and without extensions) and they are working on both simulator and iPhone, therefore the problem must be within my project. (my project does have a today extension)
In that kind of cases I usually :
Product > Clean
Close xCode
Delete the Derived Data (in ~/Library/Developer/Xcode/DerivedData subfolders)
Delete the app on the iPhone
Reboot the iPhone
Restart and rebuild
I had this problem. In my case, it was caused by the Build value being blank. After putting a value there, and resetting the simulator once more, the issue went away.
I had the same problem and checking the system log carefully helped me to identify a coliding library that was causing this error. You can also check this answer if you are using extensions.
Generally it means there is a problem with the build, it may be due to old cache (solved by a clean build) or a project definition error (missing library, bad definition in info.plist, etc).
In my case it happened only on iOS 8, turns out that my widget had the wrong bundle ID.
this happens after an error that appears in organizer several time when running the program in Xcode.
the error is Xcode has encountered an unexpected error (0xC011).
any help to guide me get rid of this problem this is highly appreciated
Even when its too late but maybe for somebody else. The problem is either in your computer nor in your xcode. You must check the way you are saving the data in the files ( saving from two resource at the same file). error (0xC011) is for logging data in files.
Check your code, then delete the app. from your device then start it. It will work.
I just restarted my computer and the organizer is working now, However,the error is appearing again that is:
Xcode has encountered an unexpected error (0xC011) ‘file
exists/SourceCache/DTDeviceKit/DTDeviceKit-2083/DTDeviceKit/DTDKApplication.m:1474
Okay, so my Xcode and iPhone simulator have become really screwed up lately, all i remember doing right before this started happening is i turned off my mac. So, my first problem is that every time i open up iPhone simulator, it says the simulated application can't be run and asks to switch sdk and i click 5.0 and it keeps on saying that. I have tried reinstalling Xcode 3 times now. Second, whenever i go to open up the MainStoryboard.iphone/ipad files, Xcode freezes up and gives me the option to either crash or continue in a poor state or something like that. Next, the app I'm trying to create used to work, but then all of a sudden, it would crash at startup with this error message:
dyld: Symbol not found: ___CFObjCIsCollectable

2012-01-03 21:02:45.802 ibtoold[1399:d03] [MT] DVTAssertions: ASSERTION FAILURE in /SourceCache/IDEInterfaceBuilderCocoaTouch/IDEInterfaceBuilderCocoaTouch-933/IBPlugin/Utilities/IBObjectMarshalling.m:179
Details: Interface Builder encountered an error communicating with the iOS Simulator. "Interface Builder Cocoa Touch Tool" (1402) failed to launch and exited with status (null), signal 5. Please check Console.app for crash reports for "Interface Builder Cocoa Touch Tool" for further information.
Function: NSDistantObject<IBCocoaTouchToolProtocol> *IBAttachToCocoaTouchTool(IBCocoaTouchTargetRuntime *)
Thread: <NSThread: 0x40010a220>{name = (null), num = 1}
That is the error that i got when beginning to run the app, now instead, it just gives me two errors while building the app and here is what those say:
Command /Developer/usr/bin/ibtool failed with exit code 255
Verify exit code of build task 'CompileStoryboard MainStoryboard_iPhone.storyboard'
Build task failed without generating error messages.
These have to be in some way related and it has either to do with the storyboard settings or the iOS simulator, this has been a huge setback for the making of my app, if anyone has had this issue, please help
EDIT: ok have been trying to see if this same thing happens on other projects and it seems to be only that app with the errors, but IOS simulator doesn't work for anything. Also, literally every other thing i try to do on Xcode now prompts a crash, even trying to open up a project and look at errors in new window.
Update to a newer version of Xcode, they run smoother and are a lot less buggy.
I am getting an assertion error when I launch Xcode 4, which I just installed. I have looked on Google and Stackoverflow, and I could not find anybody with the same problem as me. As soon as I open Xcode 4, it shows me the welcome screen. I try to open a project, and Xcode gives me a message saying I can continue using Xcode in an inconsistent state or I can crash Xcode. When I click on more details it says "ASSERTION ERROR" followed by some other debugging info. I can't copy it because when I try to highlight it Xcode freezes completely.
Any suggestions?
NOTE: This is different from other people who get this error when they build, I am getting this when it is LAUNCHED.
Could it also be because I am continuing a project from the previous version of Xcode?
[UPDATE] I have solved the problem. If you are also encountering such an error, try reinstalling Xcode 4. If you continue getting the same error, then follow the advice of #mrueg.
Xcode 4 has various bugs, and the assertion error is just a general warning that an inconsistency was detected.
The best way to get more info on the actual error that happened is to crash Xcode when you get the error and then show the details.
It probably also makes sense to send the crash report to Apple so they can fix the bug.
It is probably best to keep using Xcode 3 (which is still downloadable for the newest SDKs) and wait for the next version of Xcode 4 if your project crashes it.
