Don’t expect to, say, drop an image from Safari into Spark, or a PDF from Slack into PDF Expert. With their iPad apps, Readdle is taking a limited, but perhaps more effective approach: drag & drop works for certain file types and specific drop targets in the UI, and it’s only supported in Split View and with Spark, Documents, PDF Expert, and Scanner Pro. As I outlined in last week’s story, a native drag & drop feature would have to be an official framework created by Apple and opened up to third-party developers with an API. Since the launch of iOS 9, I’ve seen a few third-party libraries attempt to bring drag & drop to iPad apps, but all of them failed to gain widespread adoption. I’ve been testing this functionality for the past week, and, even if it’s not system-wide iOS drag & drop, it’s been enough to pull me back into Spark and PDF Expert – at least for now. Today, in addition to the release of Documents 6, the company is updating most of their iPad apps with a custom drag & drop feature that simplifies the transfer of documents between two apps in Split View. Readdle, makers of the popular Spark and PDF Expert, aren’t waiting for Apple to add a native drag & drop framework to iOS, though. In my iOS 11 wish list for iPad and concept video, I focused on system-wide drag & drop – a feature that could reshape how iPad users move documents and data between apps.
