After you sign in to the Skype for Business for iOS client (version 6.0), you see only a black screen.

This issue was resolved in version 6.0.1447 of the Skype for Business for iOS client, which was released on October 22, 2015. To download the latest version of the Skype for Business for iOS client, go to the following Apple website:

For IT Professionals
The method in the "Workaround" section works if you're running a single pool behind your Edge server and if users are homed on that pool. If there is a director or multiple pools (that is, users are homed on a pool that’s not the next hop) within the environment, Passive Authentication is unsuccessful even after you force a close and then restart the app.
