Simple application crashes

Question

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?

Answer 1

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.
