I'm writing an app that, among other things, need to be able to play several tracks using AvAudioEngine. My question is about the best practice for carrying with the App a set of tracks. I could 'bundle' them with the app but currently they are about 400MB and I think it's too much. I think that this would also significantly slow my deploy times every time I need to run/debug the app. On my iPad Pro, using the File app, I can see the 'On My iPad' folder and inside that folder I already see some folders used by others App, like Cubasis LE, Acrobat and GarageBand for iOS. I can't find any example that shows me how to access these locations and which capability I need to add to my app (if any). Can you please point me in the right direction? Thanks, Guglielmo
