iCloud Drive really is Apple's Vista. It is a terribly thought out product and it is so riddled with bugs it's almost unusable. Before I start I'm not a troll. My home and business is full off Apple products. I wanted iCloud Drive to replace my reliance of DropBox. I genuinely thought that iCloud Drive would be better integrated into iOS 8 (another Vista). I am using iCloud Drive with a Mac Pro, MacBook Air, iPad Air and iPhone. All the latest models running the latest software. For starters, I've uninstalled Pages, Numbers and Keynote from every device I own yet they remain in the iOS iCloud Drive document picker. There is NO way to remove the dammed folders. I will never use them, nor will I use the iMovie, Automator folders etc but I can't remove them. They just sit there taking up space. I have deleted ALL documents in the Pages folder using all of my devices and 10 minutes after I delete them, 1 or 2 documents re-appear on 1 or more of my devices. If I delete them half a dozen times they tend to delete. Documents can't be edited, renamed or deleted in the iCloud Drive document picker so the idea or iOS being used without a computer is impossible because a computer is needed to manipulate the files. The document picker is fundamentally broken. No matter which app I use that supports iCloud Drive, half the files display as blank icons and cannot be opened by an app that indeed supports the file type. Why oh why Apple didn't make iCloud Drive work like DropBox but with better iOS integration is beyond me. iCloud Drive could have been wonderful but at the moment it's a pathetic reason to exist.
