XCTest & UNUserNotificationCenter: requires bundle identifier, crashes when accessed

Number:rdar://27768556 Date Originated:08/09/16
Status:Open Resolved:
Product:iOS SDK Product Version:iOS 10
Classification:Causes Crash Reproducible:Always
Our push notification SDK is migrating to use UNNotificationCenter for iOS 10 deployment targets.

We have extensive unit and integration tests running in the simulator environments.

We'd like to extend our tests to support UNNotificationCenter to generate local notifications for which we can test our SDK code.

However, in doing so, even attempting to *access* the -currentNotificationCenter (via [UNUserNotificationCenter currentNotificationCenter]) crashes because xctest is not exposing a bundle identifier.
