Distributing for App Store using beta versions of Xcode
You can't submit an app to App Store with beta software, you have to wait GM release.
From Apple
New apps and app updates submitted to the App Store must be built with release versions of Xcode 5. Do not submit apps built with beta software, as beta versions are for development and testing only.
Xcode 6 beta, iOS 8 beta, and OS X Yosemite Developer Preview are pre-release software. Your use is subject to and licensed only under the terms and conditions of the iOS Developer Program License Agreement ("iOS PLA"), including any applicable consent to collect diagnostic data set forth therein. If you have not agreed to the iOS PLA, you are not permitted to use this software.

You may now use Xcode 6 GM seed to submit apps to the App Store and Mac App Store.
I have the same error till I revoke and request new iPhone Distribution certificate from Apple.
- Go to developer.apple.com, open Certificates.
- If you have 2 or less certificates for Distribution you can create new one. But if you have 3 you need to revoke one and then create new one.
- Go to Provision Profiles and select your profile. Change old certificate to just created certificate. Download provision profile.
- Now build your app.
