I've come across same problem and nothing solved it, so i found one work around
- Download provisioning profile directly from developer account and double tap on it, it will get install in xcode.
- Download and install iPhone configuration utility.
- Open iPhone configuration utility there you will find all the provisioning profile
- Then select the provisioning profile you want to use, then it details of the profile you can see Profile identifier.
- Copy that Profile identifier and open xcode.
- Navigate to the code signing identity and there in provisioning profile select others and paste the copied Profile identifier.
- Bingo!
