Not working with local file in Queue about swiftaudio HOT 1 OPEN

You should check if you have permission to read the m4a file.
Normally, you can only access the folders and files in your app sandbox on iOS .
You may have two choice:

1. use UIFileSharingEnabled, expose your sandbox directory to user in iOS Files App, then copy file to that directory in Files app, here is an example
2. Or, you can just ask user to pick files outside your app container , see providing_access_to_directories

I'm new to iOS development, so if the answer has some wrong , please let me know ,thank you !
