In my case problem was different than others. I try everything but didn't solve my problem.
Let me explain my situation before explain how I solve it.
First it starts with adding Today Extension to my project. I created different bundle ID for my App Extension. For example if my application's bundle ID com.company.appname, I created for my Extension something like this "com.company.appname.TodayExtension". I'm using XCode Version 6.3.2 (6D2105), and XCode automatically (The provisioning profile specified in your build settings (“AppName”) has an AppID of “BundleID” which does not match your bundle identifier “BundleID2”. Xcode can resolve this issue by downloading a new provisioning profile from the Member Center...Of course I click the 'Fix Issue' button) create an provision profile for Today Extension.
And just after that I added "app group" to my application and go on coding for a while. But when I try to send my application to the AppStore (Product/Archive/Submit to AppStore), I get this error that says "None of the valid provisioning profiles allowed the specified entitlements: beta-reports-active, com.apple.security.application-groups".
You must know that "app group" could be the key point for you too...
Please go to member center/Certificates, Identifiers & Profiles/Provisioning Profiles/Distribution section. Find your application's Distribution profile and select it. As you can see that status for your profile is "Invalid (like in my case). Then here's the solution, click Edit button, after that Generate button. Now please repeat this action for all "Invalid" profiles. After all your profiles are re validated, now you can go back to your XCode project and update local provisions in your Mac. Go to : Xcode > Preferences > Accounts > YOUR_ACCOUNT > View Details ..., CTRL+Click one of the Profiles and open in Finder. Move all Profiles to Trash, then refresh the Profiles".
Now Product/Clean and (hopefully for the last time) Product/Archive and Submit to AppStore.
Generally speaking, it's happen because you add app group to your application, but you didn't validate all of your profiles after that.
Maybe this will helps someone.
