There is currently an airplay issue with XBMC 12.2 (and below) and IOS 7. When streaming Airplay video to XBMC from an IOS 7 device, you only hear the audio and no video shows up on screen. This issue is being resolved in XBMC 12.3+ and XBMC 13.
For Taffy Media Center Linux users, an update is required to use airplay video which should be issued soon. All Android users should not have a problems with Airplay as it is not passed through XBMC. Airplay is passed through an Android App and therefore is problem free.
