How to fix “no valid 'aps-environment' entitlement string found for application” in Xcode 4.3?

Question

I\'ve been trying very very hard to create a simple simple iOS app which can recieve push notifications. My only reason for doing this is to establish a procedure for some

There seem to be something quirky with the 'automatic' entitlements in Xcode 4.6.

There is an Entitlement.plist file for each SDK at:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/Entitlements.plist

A workaround solution I came up with was to edit this file and add the sneaky aps-environment key manually like so:

    application-identifier
    $(AppIdentifierPrefix)$(CFBundleIdentifier)
    aps-environment
    development
    keychain-access-groups
    
        $(AppIdentifierPrefix)$(CFBundleIdentifier)
    

Then, Xcode is generating correct Xcent file, which contains the aps-environment key at:

/Users/mySelf/Library/Developer/Xcode/DerivedData/myApp-buauvgusocvjyjcwdtpewdzycfmc/Build/Intermediates/myApp.build/Debug-iphoneos/myApp.build/myApp.xcent

You can locate where your Xcent file is created using Xcode's Log Navigator,
look for "ProcessProductPackaging".

Unfortunately, this is the only way I found that fixes the issue.
(and finally able to properly get push token now)

Just wondering if another more elegant solution is available.
