iOS seems to play only audio files, selected with filechooser. Please help


in my iOS app I am able to setup a playlist with different audio files. The files are selected by fileChooser. The playlist is stored as an .xml file.
When I try to play a file by the path that is stored in the xml file everything works fine as long as I close the app.

After restarting the app and trying to load my xml it fails in the URL::createReaderFrom() function.
The FileInputStream seems not to be able to open the file correctly. (openedok() returns false)

Building for MAC everything is fine.

Do you have any idea how to resolve?

Thanks in advance.

Best regards
