Audio player for iOS

I have built the application described in the “Playing Sound File Tutorial”, extended it to accept m4a and mp3 files, and verified its operation on MacOS.
I built it for iOS, and after struggling with Xcode and certificates, managed to get it to run on my iPhone.
I can see the application and can choose on of the available audio file I added (via iCloud), but the application does not create a player for it (I verified that the file chooser selected the correct file).
Can someone help me understand how to have that player (or any other JUCE based audio player) run on a real iOS device (that was my main purpose on working with JUCE).
