iOS Scrollbars and Discoverability

First of all, Michael Gubik says

Just discovered you can drag scroll bars on iOS (you have to hold for half a second)

And, oh my god, it works.

I’ve been using an iPhone since June 29, 2007 – twelve years! – and I never knew this was a thing. To quote Hannes Oud

Is this a new feature? I guess it is, according to Jared Sinclair

@steipete I would keep the custom handle. I’m a developer and an Apple nerd and even I didn’t discover the new feature until someone showed me, and at this moment I can’t even remember how to do it.

If developers as tuned-in to the Apple ecosystem as myself and those quoted above had no idea about this feature, how on earth are normal users ever going to figure this stuff out? Do we just accept that scrolling quickly (by dragging) is only for power-users – like keyboard shortcuts on a desktop? (Well, to be fair, at least keyboard shortcuts are discoverable since they’re listed next to each menu item.)

This all goes back to discoverability and flat design and UI affordances. Back to when a button looked like something you could click or tap (or lick). Matej Bukovinski, of fantastic PSPDFKit fame, writes:

We were considering dropping our custom drag handle in favor of the new draggable scroll bars. However, discoverability is simply not good enough. I’m sure everybody tried it when fist getting an iPhone and then made peace with the previous behavior.

It’s great to see 3rd party developers trying to improve the situation for their customers. It just sucks that they need to.

I’ll leave you with this.
