I have been reading about this prob

Answer 1

In my case it was because the xcode 4.0.2 prevented deletion of stale data in the project.pbxpro in the *.xcodepro directory. I ended up hand editing the file after shutting down xcode. In the file I looked for all of the occurrences of "PROVISIONING", something like this:

PRODUCT_NAME = Xyzzy;
PROVISIONING_PROFILE = "CF5F0AEA-92D9-48E1-99DF-301AB36C2BFB";
"PROVISIONING_PROFILE[sdk=*]" = "CF5F0AEA-92D9-48E1-99DF-301AB36C2BFB";
SDKROOT = iphoneos;

and changed it to:

PRODUCT_NAME = Xyzzy;
"PROVISIONING_PROFILE[sdk=*]" = "";
SDKROOT = iphoneos;

I restarted xcode and the build succeeded with out issue. A word of caution make sure that you back up the project directory before make changes to the project files, and only hand edit the files when you have no other options.
