title: How to handle NSExtensionActivationRule is truepredicate?
body: <p>I got warning:
  Embedded binary's NSExtensionActivationRule is TRUEPREDICATE. Before you submit your containing app to the App Store, be sure to replace all uses of TRUEPREDICATE with specific predicate statements or NSExtensionActivationRule keys. If any extensions in your containing app include TRUEPREDICATE, the app will be rejected</p>
  
  <p>what can I do? I try to modify NSExtension, but I really don't figure out how to solve it.</p>
