iPadOS
The new OS doesn’t look dramatically different from iOS 12, this actually might be the most low-key update that they’ve had in a while, but the name change undoubtedly makes it easier for Apple to introduce functionality to iPads that won’t exist in any capacity on the iPhone. Changes in iPadOS include an update to the Files app which will allow you share folders in iCloud drive, there’s a new column view and you’ll be able to grab files from USB-C flash drives. You’ll be able to bring up multiple windows of the same app, which wasn’t previously possible and there are a lot of small interface changes that make it easier to multi-task with your larger screen real estate.
