I am developing an application on macOS in SwiftUI which exchanges files with other processes on a network. Some of these processes may be on Linux and write to a network drive. The files are refreshed at 10, 15 or 60 second intervals, and keep the same name. The software is supposed to run 24/7 and have persistent paths, so that on restart it does not need setting up. And it runs in the sandbox.
I have got this working with macOS-only external processes by putting the exchange files in a fixed folder on the network storage and using security-scoped bookmarks to the file and or folder.
But it doesn't work so well when one of the writing processes is a Linux process writing to its own storage. I can put a symlink in my fixed folder and if i select the folder and the symlink after each app restart, it works.
but how can i make such a set-up persistent so it works after app restart without manual selection?
