Xcode will run app on simulator but not on device

I receive the following error when trying to run the app on my device.

error: failed to launch '/Users/michael/Library/Developer/Xcode/DerivedData/Build/Products/Debug-iphoneos/Word Processor.app/Word Processor' -- No such file or directory (/Users/michael/Library/Developer/Xcode/DerivedData/Build/Products/Debug-iphoneos/Word Processor.app/Word Processor)

The app runs fine in the simulator. When I try to debug on the device, it appears to copy the app (I can see the icon), but then stalls with the above message. Xcode says it is running the app on my iPod, but nothing is happening on my iPod.

When I click on the app, the app appears to launch, but seems to be missing resources. Other projects of mine work properly. What setting do I need to change to make this work properly.? Looking at the error message, it seems to be looking in my mac for the app. But this doesn't make sense since I am trying to run it on my 4th gen iPod touch. I am using Xcode 4.3.1 and iOS 5.1

This is a recurring problem that many developers are having with the current version of Xcode. The temporary workaround has been consistently deleting the DerivedData folder.

You can add doing it to a build script or even make it a cron job:

rm -rf ~/Library/Developer/Xcode/DerivedData

Sad, but true.
