It was always going to be too early for Apple to announce anything about automation at WWDC. We're probably looking at iOS 12 before the Workflow acquisition starts to bear any native fruit.
Perhaps we'll see some fledgling - and by that I mean beta - functionality in a later point update but, if we do, it will be minimal.
Seeing as so much of what I do now goes through Workflow I've been thinking about the implications of becoming so reliant on a single solution. Likes, replies, microblog posts, titleless posts, the microcast, they all rely on Workflow.
Apple won't have acquired the app without having a plan for it or its developers, and some form of native automation seems almost inevitable, although most likely in the context of Siri and AI rather than in Workflow's current remit.
Once any native automation arrives I can't help but feel that the Workflow app will be pulled from the App Store potentially leaving quite a vacuum in its wake.
Perhaps other solutions will appear by then. Perhaps native automation will be more powerful and versatile than I imagine. Perhaps I'm worrying over nothing, however, I doubt it.
We may be some time from any changes but the sooner we assess our options the better.
