I’m storing my offline draft files in the iOS document directory(getApplicationDocumentsDirectory). I could use the files within a few hours. But when I go to my draft page after days and want to upload my draft files, its showing no such file in that directory. Why this happening in iOS? In Android, it’s working fine but in time of iOS, files get lost after a few hours without deleting these files. Is there any reason or how I could store files on iPhone and use it for offline.
