I have developed a simple app that calculates the risk of developing type 2 diabetes. The app runs fine from xcode on my iPhone 3Gs. I archived the app in a .ipa file and I have uploaded the app to my testflightapp.com account. I have installed the app on my iPhone with the standard testflightapp.com procedure: clicking the install link in the email from testflightapp.com.

When I run the app, I see the launch image for a few seconds and then it goes away. The console of my iPhone in xcode displays what is going wrong, but I do not know what this means:

Can anybody shine a light on this error?

    Check the saved crash report using the Xcode organizer or the iPhone Configuration Utility. – Till Jan 08 '12 at 19:17
  • There is nothing in the console log that can help to answer - you need to post crash log – AlexeyVMP Jan 08 '12 at 19:19
  • Yeah - as others have mentioned - this isn't the problem with the application on your phone. This is the problem with the debug version (and this can happen easily during the development process). You need to crash log from your device - and you can read here to get it: http://stackoverflow.com/questions/3844482/iphone-how-to-get-crash-log-from-customers – dtuckernet Jan 08 '12 at 19:40

On the iPhone, a process of a previous run of the application was still active. To fix the issue, all that is necessary is a reboot.
