I have this very old camera app Luma (downloaded it with iOS 6), which has numerous recordings stored in it but as of iOS 8 have been inaccessible. I want to save these files to my Mac if possible, and delete them from the app to free up storage. The problem is － as the app is no longer supported after having been sold to Instagram circa iOS 7 － the app crashes in iOS 9 when trying to open its gallery (necessary to export from gallery to the camera roll to save to computer), and in iBrowse, the files that still are in the app are invisible and nonextractable. iBrowse screen capture shows no visible files Screen capture shows files in gallery (taking up space), immediately before crashing Luma crashing when trying to access its gallery Is it possible with any Apple Developer tools or XCode, for example, to force-extract from the phone the [invisible] files? Or is this a lost cause and I should delete the app?
