With iOS 9, Apple introduced a new mode of building and distributing iOS apps called App Thinning. As part of this initiative, apps containing bitcode are delivered.

If you choose to create your app containing bitcode, the process of acquiring your dSYM files for upload while you are in local development, debugging, and testing mode (Xcode on simulators or Devices) is exactly the same as in earlier versions.

It also works if you are using Ad Hoc Provisioning. But once you have used iTunes Connect to upload your application to Apple, for either TestFlight beta testing or application release, you have to take a few additional steps to get your dSYM files for use with Splunk AppDynamics.
