Hi all , I'm sure many like me were expecting more from Apple when it came to the iCloud Drive experience on ios. I have been trying to create a dropbox like experience and think I have managed. Download goodreader, enable iCloud in settings. Once enabled add documents into this area, dropbox etc can be added as sources in the connect option. Simply download everything into the iCloud section. If you don't want the files on the device but in the cloud select the folders in the manage files option and click evict, this removes them from the device but there on cloud if needed. Have transferred loads from dropbox, skydrive and Google drive, evicted it all so it's now on the cloud. Hope this helps if anyone else was hoping for a centralised cloud storage option.
