Because I can't help myself, I was early to the game with the iOS 10 betas this year. As a nerd, I find it generally fun to be at the bleeding edge technology. When something goes wrong, I don't blame Apple because it is, after all, a beta. Most things that break in beta get fixed before the final product ships.
As such, I usually don't worry too much about problems in beta. I am, however, concerned about the "Save to iCloud" dialog box in iOS 10. Here is a screenshot.
In iOS 9, the Save to iCloud dialog box was a little buggy but generally worked. It had a search bar and a way to navigate through your folders. Starting with iOS 10 beta 1 we got the above Save to iCloud dialog box. They've removed the search function and instead made it a very long scrolling list of folders. There's no way to collapse the folders and no way to jump to a specific destination. Instead, every time you want to save something to iCloud, you need to scroll through a seemingly endless list until you find the folder you want. In that process, you need to be very careful. If you scroll too fast and the iPad mistakes your swipe for a touch, iOS 10 saves the file to whatever folder you happen to touch. As I discovered, it's not always easy to figure out exactly where things end up. With every new iOS 10 beta I go back to this thinking it will have improved. So far it hasn't.
This new Save to iCloud dialog box is unusable for someone that has more than a few iCloud-based folders. When this arrived, I was in the midst of a two-month experiment running most of my cloud-based files off of iCloud. There were good parts and bad parts but it was workable. This dialog box put the brakes on the whole experiment. At first, I thought it was simply a placeholder until they made something better. But now they are up to the fifth beta and there still has been no change with this dialog box. I'm starting to get worried that this is what they intend to ship.
Does anyone at Apple use more than 100 folders on their iCloud drive? If they do, this has to be a pain point for them. I know we still have a month or so before iOS 10 ships and I really hope that I end up looking like Chicken Little with this post but if Apple does not improve the Save to iCloud dialog box before iOS 10 ships, it's going to be difficult to use iCloud with any significant number of folders.
