I installed xcode 4.5.1 for supporting iphone 5. After creation of the archive, the validation of the app passes without error. but afterwards during distribution when uploading the app, the following error is shown: The following issues were found during validation: An error occurred uploading to the iTunes Store.
Uploading was possible with xcode 4.3. In iTunesConnect I just see "Waiting for upload" but no error log. Is there a local error log that shows more details? What could be the reason for the error?
