The Accio script causes several "not permitted" and "directory not found" issues when building a project with extensions, e.g. NotificationContentExtensions.

When adding extensions to an Xcode project Xcode creates a new target for each extension. In some cases, we need to access some functionality of the app, e.g. accessing a Realm Database within a Notification Extension requires to include the Realm Framework to the Extension Target.
By doing this and running accio install Accio automatically adds the Accio script to the target. This will cause problems while building the project because several scripts are executed at build time. Therefore I propose to add a flag or possibility to disallow adding the Accio script to a specific target.
