I had a couple of questions someone could help me with, as I’m trying to do a little research for my team before they do a bunch of coding. We’re building an anywhere-to-anywhere encrypted file transfer app and wrestling currently with our share functionality. Currently, our users log into their app on their phone, and: within the application use a file picker to select files/photos and then select a destination that they pick from a permission-ed list. However, we really would like to also add the workflow where the user opens the photos or files app, finds a picture/file and then uses the share functionality to pass the object into the application, then The application launches, allowing the user to log into the app, then they pick from a list of permission-ed drop targets within the app and send the object In doing some research this morning regarding sharing files/pictures within our application, I found this thread Eskimo had more or less advised against what we intended to do: https://developer.apple.com/forums/thread/114485 We don’t want to save session tokens because of security concerns; we’re concerned primarily with third-party actors (governments primarily) having access to encryption keys. Is there a best-practice way for my team to open the app we're building and then passing the files/photos into our application? Does anyone have any advice on how to securely launch the application and pass the file/pic into the app given the constraints? Thanks!
