Drag and Drop on iPad: by Readdle / by Erin Wade

At the World-Wide Developer's Conference (WWDC) on June 5th, 2017, Apple made a number of announcements, among them significant changes coming for the iPad in iOS 11.

One of the changes garnering the lion's share of attention is the upcoming addition of drag-and-drop capability to the iPad. This isn't entirely new - there has long been the ability to drag around items within a given app, but not between them.

This represents a significant advance for the iPad in general, and is particularly exciting for those of us who work at or near an iPad-only status. Unfortunately, it's mostly a tease at the moment. iOS 11 won't come out until the fall, and while it is possible to sign up for early beta's of the software, working with an operating system still in development on one's work devices simply is not the wisest of choices.

However, if you are looking to get some experience with how drag-and-drop works now without taking the risk of using a potentially unstable operating system on your production machines, Readdle has you covered.

Their announcement likely got a little lost in the excitement of WWDC, but back at the end of May, Readdle announced the capability to drag and drop files between their apps - specifically between Documents, Scanner Pro, PDF Expert, and Spark. I use all of these apps except Documents (PDF Expert largely replicates the capabilities of Documents while adding the PDF functionalities), and I'm pleased to say it works extremely well.

Say you've received some documents via email that you want to review and mark up. Open your email in Spark, and open PDF Expert in a split window, and simply drag the files from the email across to the folder you want in PDF Expert. It's that simple and straightforward. You can see it in their video, below:

The utility of this is quickly obvious, and Readdle has just about the perfect family of apps to use it with. Their is a brief explanation in their blog post of how they are doing it - servers opening and such - which would make it seem like something potentially clunky and slow, but it's seamless in application. The only limitation here I've seen thus far is that, because it relies on off-site servers, it doesn't work if you don't have an internet connection. Under those circumstances the file you are dragging simply stops at the window split. If you have, or go get, these apps you can test that yourself by putting your iPad into airplane mode.

Readdle has a fairly long history of developing applications that recognize and address some of the limitations in iOS, and this is a nice example of that. I actually feel a little bad for them that the announcement of this capability came such a short time ahead of the WWDC announcement, which takes Readdle's drag and drop capability and applies it system-wide. WWDC also announced a Files app, which appears to largely do everything that Documents does. Still, Readdle puts on a brave face on their blog entry about WWDC, indicating:

It’s great to see Apple focused on unleashing true iPad potential, while adding some tremendous improvements to the dev tools and kits. People will enjoy the new experience on the App Store, get more apps, and do more stuff done with their iOS devices.

We will dig deeper during the week and come up with awesome ideas on what we are going to do with iOS 11 and Readdle apps.

Based on their history thus far, I suspect they are up to it.
