Here's how my app used to work: On one device, generate a text file with a custom extension. Send it via AirDrop or in Messages to another device. Open the file in another copy of my app. The app processes the data correctly the way I want. Now, when I try to do this, I get this: Error Domain=NSCocoaErrorDomain Code=257 "The file “Shopping List.sld” couldn’t be opened because you don’t have permission to view it." UserInfo={NSFilePath=/private/var/mobile/Library/Mobile Documents/com~apple~CloudDocs/Downloads/Shopping List.sld, NSUnderlyingError=0x282280a50 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}} file:///private/var/mobile/Library/Mobile%20Documents/com~apple~CloudDocs/Downloads/Shopping%20List.sld I think this broke with the iOS 17 upgrade. What permissions or capabilities do I need to add to my app to do that, and how do I go about adding them? I am quite new to xCode and iOS developement, but I had this working before.
