Xcode says it cannot launch app when it in fact does run - iphone

What do I do about this?
Xcode launches the app on the device and it starts up, but when it has started the image below pops up and when I click "OK" it crashes the app.
The simulator has no issues, but I cannot read the console in regards to debugging because of this. There really is not a reason why this should be happening.
Also I have no idea what code could cause this. I have no errors or warnings and everything has been fine right up until yesterday.
If there is any code or more info you need to help me with this, please ask:-)
I have removed the app, restarted the devices and my mac.

Ok I found the answer here:
Same issue here
Basically you can't do debugging on a Ad-Hoc profile:-)

xcode simulator crashing xcode when trying to run app

I was propted by apple to upgrade my debugger settings yesterday, In doing so I have some how broken xcode.
When ever I now try to load an application (dosn't matter what version of the simulator I am using) Xcode and my simulator both freeze up. then the rainbow loader just sits their constantly turning over.
Is there any way to fix this? I'm really stuck and don't know what to do as it dose not seem like a very common problem from all the research I have done to fix this.
I am running the latest version of xcode 4.3.2 (4E2002) and using 5.1 simulator.. and have tried 4.2 simulator to the same effect.
any help in getting my xcode back up and running would be massively appreciated.
Okay so I figured out what the problem is but not a real solution...
Basically the error started happening when I was prompted by xcode to update my debugger to the LLDB version. this is what cause my simulator to keep crashing xcode.. or vice versa honastly I still dont know why this is happening but yea...
so.. what I did to get this simulator working again was go to Product>edit scheme> debugger then changed from LLDB back to GDB.. this solved my issue for now... however I need to figure out why LLDB is not working and what I should do leading into the future. hope this helps someone else.
I have facing this problem too but I got a solution either you said its temporary ... some time ios 5.1 simulator hangs when I shifted to the ios 4.1 sdk its a common practice for the developer to check it I have simply first close the simulator and again start it and then reset all the content in the preference area that its resolved my issue .. check it might be you also got resolve for apply this trick or technique.
Thanks
In my case, was too many old breakpoints tracks (788), even to deleted files, I just clean it and now it runs perfect, I hope it helps.
A picture to illustrate:

SIGABRT on iPhone but not simulator

My IPhone app is suddenly giving a SIGABRT error message when I attempt to run it on my iPhone, before even the first line of the application delegate is reached. It runs fine in the simulator, and even restoring previously working snapshots give the same error when I attempt to load the application on the device.
I fiddled with the Product Name build setting and the data model prior to the problem occurring, but as mentioned, old snapshots that ran fine now won't load, suggesting that the problem isn't in the code.
I have tried restarting xCode, the computer, the iPhone and deleting the app but the problem is still occurring.
I am sure that the problem lies with the device
Any ideas what the problem might be or how I can fix it?
Taking on Till's suggestions I reinstalled iOS (well, actually I updated it to 5.1) and everything is working again. Thanks for the advice. I've no idea what went wrong, but at least its working again now!

Application running on iOS4.2 but not on iOS5

I have an application of which i have created .ipa file and tried to run the application on iOS5. If i run it on iOS 5, it works but when i try to run it on iOS4.2 it doesn't work. It opens up, shows black window and then back to home screen. I have tried things like deleting app, installing again, restarting phone, reseting it's setting.
I know most people face vice a versa situation. Let me know if any one of you have good solution for it.
Thank you,
Anks
Your only hope is the console, see what it says about why it is dying. If that doesn't give any messages, stop it in the debugger in AplicationDidFinishLaunching, and step as far as you can...
The console though SHOULD have a message about why the app is terminating early. Without knowing why, we cannot help further.
Did you change your build target immediately before creating the .ipa? If so, do a clean build and then re-create the .ipa file again—that may fix your problem.

Why is XCode Organizer console sometimes empty when I connect my iPhone

When testing my iPhone app I have found it incredibly useful to log information to the console window. I think it is amazing that I can send out an adhoc build to my co-workers and if they experience problems I am able to plug their iPhone into my mac and grab their console output. However, sometimes the console window is blank when we do this. Why is this the case? The code has been built with logging enabled. Besides that, it seems that the console output, when I see it, contains information about not only my app, but other iphone system logging.
Thanks for any insight you can provide.
It looks like if I restart XCode then the console gets populated properly. Must be a bug in XCode, but restarting seems to always work.
It seems to be a new bug in 3.2.3 - older versions worked fine.

iPhone app was working, suddenly starts crashing on startup, reinstall fixes, but why?

Here's the situation:
-Had a development build of the app we just submitted on my phone, working fine for days (and previous builds worked fine for weeks).
-Yesterday, I touched the app icon, the app launches then crashes out (I wasn't connected to my computer at the time, but if I had to guess, it was around or before when applicationDidFinishLaunching runs). Basically, I briefly see my Default.png, then the app closes. This happens every time I try to run it.
-I restart my phone. No difference, the app is still failing to launch. All other iphone apps I have appear to be working fine.
-This morning I reinstall the app from my development computer and all is well, it's working fine again. No problems. This is the SAME EXACT CODE with the same build parameters.
This has me really worried, does anyone have any idea at all what might have happened? It's like the app permanently broke itself, before it even hits any of my code no less :(. I had a theory it might have had to do with an expired provisioning profile, but I didn't get any message then or when I reinstalled.
I'd appreciate any advice/pointers/ideas people have!
Connect your iPhone to the computer, launch XCode, go to the Window menu, and select Organizer. Click on your device in the left hand bar, and check your crash logs.
That should tell you when it is crashing, and why.
Actually, the crash logs should still be there from when your app WAS crashing, so even if you have reinstalled, you may be able to figure out what WAS going wrong.
Are you using core data?
Did you change your schema? That would cause a crash on startup and a reinstall would then fix it.
If it was the exact same code it seems to point to a data issue.
