Where is app_id value stored in xcode 6? - ios

Question

I've lost 2 hours searching the apple developer docs, google, and stackoverflow. Where can I find my project's app_id in Xcode 6?
I am trying to adapt the apple keychain sample code https://developer.apple.com/library/ios/samplecode/GenericKeychain/Listings/ReadMe_txt.html#//apple_ref/doc/uid/DTS40007797-ReadMe_txt-DontLinkElementID_11
but I've never had to use my app_id before. Thanks for any suggestions.

Notes: When you app created in iTunes Connect, apple assigns a app_id to your APP, then you can check it in "More->About This App"

Method: storeSecureValue
