No launchable executable present at path

I was having problem ” No launchable executable present at path ” when migrating from 2.2.1 sdk to 3.0 sdk. Althoug the application had 0 error and 0 warning the state continued. I got this problem solved by following these 2 steps.

• Close all instance and main xcode application.
• Go to application folder of concern and simply delete the build folder and click the xcode executable in your application folder to start.

This should solve your problem.
