I'm getting a weird bug on Xcode 4.5. When i tried to run my application on Ipad 2 from xcode with iOS 6, I'm getting this error.
I done the following methods to run the application, but no luck.
Cleaned the project and run
Restarted the device
Restarted xcode
I have a valid certificate in my machine and the application is installing on the device but it's not launching automatically. What could be the issue ?
Thanks in advance
That is really annoying. This error happens in a number of different situations. Sometimes restarting the Xcode, fixes the problem. If not, follow these steps:
Disconnect your device.
Delete the app from your device.
Quit Xcode (Do not just simply close the window, quit it)
Delete derived data folder (~/Library/Developer/Xcode/DerivedData/-gbrvhlvwmpiobxdujegtghggrffp - or something like that)
Now start Xcode once again, connect device and run the project. It should work fine.

I am using XCode 4.3.2 and trying to open an already existing project based on the Facebook SDK sample Project for XCODE and run it on a target IPhone with IOS 4.2.
Although it runs on the simulator it crashes on the IPhone printing this error on the console:
failed to send the qLaunchSuccess packet
I really do not know what could be the problem
This happened to me when I accidentally tried to do a device debug using a distribution profile. As soon as I noticed and switched it to a dev profile, the issue went away.
You might have some broken privileges or a hung debugger process (one that didn't quite exit fast enough). Restart Xcode or restart your phone, either way, it's not as bad as it's more annoying cousin, Processes That Can't Be Registered To The BootStrap Server
If all else fails, restore it from a backup.
In Xcode 4.3.3, this is caused by re-running the app (command+R) or stopping it (command+.) while halted on a breakpoint. To fix the error once you've gotten it, it usually works to stop the app, (command+.), unplug the device, plug it back in, and run the app again.
To avoid the issue in the future, remember to continue (command+control+y or hit the play button near the debugger output) before stopping. If you have many breakpoints or are in a loop, you can deactivate one breakpoint by going to that line and hitting command + \ or you can deactivate all breakpoints by hitting command + y.
If you eventually get the error ending in "This generally means that another instance of this process was already running or is hung in the debugger," you need to reboot the device.
I submitted a bug report to Apple. I suggest you all do the same so that this gets the attention it deserves.
Edit: the "qLaunchSuccess packet" bug doesn't happen in Xcode 4.4 or 4.5 as it did in 4.3. However, 4.4 and 4.5 experience "Timed out waiting for app to launch" instead--possibly the same issue with a new message. See this question for some possible solutions. Nothing works for met yet. The behavior seems different than 4.3.3 because the error doesn't come up every time I stop while halted on a breakpoint. I will experiment and see if my workaround for 4.3 also fixes the 4.4/4.5 issue.
I get this every time my app crashes, and I restart it by doing a Run. If I hit the Stop button before doing a run then I don't get this.
After some time, if I keep hitting Run instead of Stop first, the iPhone will only show the above error message and the only solution is to restart the iPhone. Quitting and restarting Xcode does not help.
This may be an Xcode bug.
A slightly quicker way to resolve this issue without restarting the device is to change the language.
Settings - > General - > International (4th from bottom) - > Language (top)
Alternatively If you have a bugged News stand app (in a folder) just tap it to restart springboard.
I had this error when I was trying to install over a bad version of the app that had been crashing on launch. Restarting Xcode and the device did not make the error go away, but deleting the app fixed the problem.
I am working on my first application for iPhone and I'm facing this weird problem for quite some time now.
Whenever i kill my application manually and then again try to restart, it crashes immediately with error:
Thread 1: Program received signal: "SIGKILL"
But when I again recompile and launch my application, it works just fine. Can't i just make my application to start from the same settings with which it launches when i compile and run.
I'm new to iPhone development and i think i'm missing something grave here. Will appreciate your help on this.
Thanks in advance!
So you are running the app from Xcode. If you run it from Xcode and quit it manually(not from Xcode) and try to run it from Xcode, you will receive this exception. No need to bother about this exception.
It seems to be a bug in Xcode. When you quit the application manually, no signal/intimation is sent to Xcode that the app quit running. So, Xcode thinks that app is still running. When you try to relaunch it from Xcode, it throws the exception.
I don't know the technical reason for this. May be when you relaunch the app after killing it manually, Xcode thinks that app is still running and tries to stop it before relaunching it, and throws the exception there.
I am trying to display my iphone/Ipad app on my iPad but getting this error, I checked this app on device earlier but now its giving error on console.
**warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/usr/lib/info/dns.so (file not found).**
**Couldn't register com.domainname.abcdef with the bootstrap server. Error: unknown error code.
This generally means that another instance of this process was already running or is hung in the debugger.Program received signal: “SIGABRT”.

My application working fine on Simulator but giving this error on device provided that yesterday it was also working on device with same code.
I restarted Xcode , deleted build folder but no succes.
I just restarted the device and deleted the build folder and not its working ...
but I think it could working just by restarting the device ...
Plz do as following...
Restart iOS Simulator and then Reset contents and settings and then delete build folder from directory path and then clean all targets after this run your application...
I am not sure about this but when i got this error I had done the same thing and solved this error..
Remove your device and connect it again.. and restart XCode and then try again..
Restarting Xcode will surely resolve this error....
Problem
Unlike people have asked at here and
here, I got this error after a brand new installation of Leopard (hackintosh), this problem really driving me crazy and nowhere else to find an clue, I googled and visited every article related with this, still can't get it solved.
After the first time install iPhone SDK 2.2.1, start a new project(any type, Navigate based, OpenGL ES application), then build and go, I got the following problem:
sometime it's:
Failed to launch simulated application: Unknown error.
and sometimes it's:
Failed to launch simulated application: iPhone Simulator failed to find the process ID of com.yourcompany.[application name]
It seems that apps in the simulator crashed immediately, so Xcode can find the process ID.
Solution
This link says that this even can't be solved. Some others make a detailed step by step:
Uncheck Info.plist
Quit XCode
Delete directory /Lib/Caches/com.apple.DeveloperTools.###
Open Xcode project
Clean All Targets
Rebuild
and I reset the iPhone Simulator. This also didn't solve the problem…
I've even tried uninstall the SDK and reinstall it, still got the same error…
Is this a problem related with hardwares? or the operating system version? I'm using a hackintosh (iDenebv1.4 10.5.6), all other software works good including iTunes && vmware fusion.
Great thanks for any further tips or clues!
FIXED For the issue:
iPhone Simulator failed to find the process ID of com.yourcompany.[your application name]
I was having an issue building and simulating a project I built under OS Version 2.2.1, which I could no longer get to build and run in the simulator for XCode 3.1.4, even though I forced XCode to build for "Simulator - 2.2.1 Debug"
I was able to get past this problem by:
- Close the iPhone Simulator
- Putting XCode into View->Detail
- Opening the "Info.plist" file in the "Resources" folder
- Near the top of the file you should see "Info.plist" with and up/down arrow selector
- Click on the up/down arrow selector
- Select "Clear File History"
Built For:
Simulator - 2.2.1
XCode Version:
3.1.4 (Which includes OS3.1 Beta 3)
I had the same issue last night, and suddenly my system got reboot. At that moment, i was trying to install an application into simulator. When system returned, and i tried again to install the app, it said, "Failed to launch simulated application"
Than i did googled it, and tried many solutions, like cleaining all targets and try building again, but didn't worked out.
So i have found the following link, where it is described, how to reset the iPhone Simulator contents:
http://developer.apple.com/iphone/library/documentation/Xcode/Conceptual/iphone_development/125-Using_iPhone_Simulator/iphone_simulator_application.html
I tired doing it, and you guys would'nt believe me, it worked :) ,
Solution was : "To set the user content and settings of the simulator to their factory state and remove the applications you have installed, choose iPhone Simulator > Reset Content and Settings"
Best of Luck to all.............. :)
This ends up being a product name issue:
The fix is to revert back to
${EXECUTABLE_NAME}
${PRODUCT_NAME}
for the executable file and com..${PRODUCT_NAME} in the info.plist.
Clean XCode, Quit, rese and quit simulator and you're good to go.
found some wierd log in /var/log/system.log.

Here is a discussion about how to run app in simulator via command line, hope it helps to understand how does xcode and simulator works.
But I didn't work it out.
Well, I "solved" it by install another distribution of hackintosh(IPC 10.5.6), works perfect!
In my case, I was adding a target to an existing app that had always worked. In my case, I had forgotten to select all the source code, xibs, frameworks, etc. and click their target checkbox. My clue was that the build happened instantaneously, which didn't make any sense. It never built anything. It just failed to install in the simulator. Once I included all the source files, etc., for the new target, then it built and installed fine.
I had the same problem, I fixed it by launching the simulator through another app and deleting the app I was trying to run on it. Then try to build and run and worked perfect.
Cheers
Matt
I had the same problem. I had accidentally added my info.plist file to my target and it was getting copied to the app bundle every time I built the application. So there were 2 .plist files in the bundle - mine and the Info.plist, created by XCode - which confused the simulator.
Simply delete the app from the simulator (and/or device if you're attempting to run on your device) via the UI of the simulator, then shut the simulator down and attempt to re-run the app. Doing the deletion of the actual files backing the simulator will also remove the app and do the same thing (but the deletion via the simulator's UI, if it works for you, is a little bit faster and easier).
Is your CPU Intel, and, of a model distributed in Apple hardware?
I doubt the Simulator will work reliably (if at all) on non-Intel CPUs and/or in VMWare. The simulator is very CPU specific in order to reflect the arm hardware of the iPhone.
The SDK ONLY supports Intel hardware from Apple.
There is a significant effort involved in creating the simulator and it's not easy or cheap (read, thousands of man hours) to support every CPU.
I fixed this problem by removing the "Icon already includes gloss and bevel effect" property from the Info.plist file in my project.
My problem centered around a Product Name the simulator simply wouldn't accept. Picking alternative names got me past the problem. Changing the name back to the original suspect choked the simulator every time.
Try moving the project to your local hard driver and opening it from there! That solved the issue for me (the project used to be stored on a samba share).
My fix:
restarted the Mac and it was fixed. (before that tried clearing caches, deleting caches from iPhone Simulator, cleaning, rebuilding, quitting OS, quitting Simulator, nothing worked.) Restarting the OS worked.
This was bugging me too but finally got it working.
Unfortunately, I can't reproduce what I did it but here's my list of actions for your information.
The project causing the problem was one I'd downloaded from Apple and tweaked.
Interestingly, I could still launch my own projects fine.
So, here's a list of actions that I did (note that none of the actions below worked just by itself):
- closing the simulator and doing "clear file history"
- restarting simulator
- rebooting
- restarting xcode
- resetting the iPhone with Reset Content and Settings
However, by the time I'd tried all of the above with a fresh version of the code I'd downloaded - it was working again. Just out of interest, I dragged the project that was causing this problem back to the desktop and it was OK now.
Wow, what a pain. I had to uninstall XCode 4 via the command line and then install XCode 3 again. Make sure that you restart after you reinstall. Working...
why anybody didn't tell about restarting simulator.
In my case,
Resetting the iPhone with Reset Content and Settings
and
**ReStart Simulator**
works well~
I had the exact same problem - I reset the iphone simulator and then quit the simulator then started it again.
