Summary:
Using the JavaScriptCore framework and a deployment target below iOS 7 gets your app rejected during App Store validation.

Steps to Reproduce:
1. Link the JavaScriptCore framework to your app
2. Set your app’s deployment target to iOS 6.0 (or anything else below 7.0)
3. Submit your app to the App Store

Expected Results:
Your app passes validation since it doesn't violate any rule regarding non-public APIs.

Actual Results:
Your app is rejected with this error during App Store validation:
"The app links to non-public libraries in Payload/MyApp.app/MyApp: /System/Library/PrivateFrameworks/JavaScriptCore.framework/JavaScriptCore"

Version:
Not applicable

Notes:
The JavaScriptCore framework forces linking to PrivateFrameworks/JavaScriptCore.framework when targeting iOS below version 7. See http://stackoverflow.com/questions/23514579/javascriptcore-framework-availability-on-ios/23514580#23514580 for a detailed explanation.

Greg Parker (engineer at Apple) said about this issue on Twitter (http://twitter.com/gparker/status/471722157295140864):
"Either the store policy should be changed to allow it or the SDK should be changed to prevent it."

The JavaScriptCore C API has been stable for a long time so linking to a version of the JavaScriptCore framework which is inside PrivateFrameworks is not an issue.

Please update the App Store policy to accept apps linking to PrivateFrameworks/JavaScriptCore.framework.
