Since iOS 8, Apple has supported document providers and extensions, which allowed content and files to be “shared” between applications. Often times, this felt unpolished, and was just complicated enough to be beyond your everyday iPad user. In iOS 11, however, Apple is borrowing yet another page from the classic computer interaction, allowing users to physically “pick up” (touch) almost any piece of data, and move it into any other app on the device.
Even more impressive is how iOS 11 will handle mis-matched file types and multiple content selections. Dropping a picture into the Maps app, for example, seems like it would do nothing, but thanks to image metadata, Maps will instead show where the photo was taken. Grabbing a chunk of text, an image, and a map, and dropping them into Notes will create a beautifully laid out document of your dream vacation.
Paired with the Files app, this becomes a huge productivity boost for collaborating or communicating via email, or for creating content rich documents.
