XCode--When do I sign with developer provisioning profile vs distribution profile?

Question

I am trying to prepare my app in Xcode 4.6 for enterprise deployment. I am getting this error: "failed to get the task for process 5057".

Under the project's build settings' Code signing identity section, I have selected the iPhone Distribution provisioning profile that I made for my app (it is valid). I did not select the development provisioning profile as my identity, b/c I'm trying enterprise distribution.

But of course, I get the error "failed to get task for process 5057". Why am I getting this error? I know that the fix is to use the development provisioning profile, but why--I want to prepare my app for distribution.

Should I have two schemes for my app, one for development and one for release? And inside the dev scheme, I use my dev provisioning profile and inside my release build settings, I use my distribution provisioning profile?

XCode has made this very confusing.

Failed to get task sounds like you're trying to run this build via Xcode on device. If that's the case, you want to use a development profile, not a distribution profile (AdHoc). If you're attempting to create an enterprise release build, you'll want to select your target and choose the iOS device option, then use Product > Archive to create a release build.
