The update for Airturn (in iReal Pro v8.0.2) provides compatibility with iOS11. The window shows images of their various devices; it seems you can tap on your device and it selects the correct connection method. (Remember to turn on bluetooth and pair your Airturn device first).
(From our initial tests, if your device was already connected and working with iReal Pro before this update, it will (should!) continue to work without having to do anything, although we cannot be sure this will be true for all cases.)
