How I got back Slide Over on my iPad Air
I’m generally loathe to provide tips on weird iOS wobbles, because too many of them feel like voodoo. But after a week of Slide Over failing on my iPad Air, I managed to get it back, and I figured my method might help other people.
Slide Over is a new feature in iOS 9. On iPads other than the iPad Air 2, iPad mini 4, and the upcoming iPad Pro, it’s the only means of getting two apps on the same screen, without jailbreaking. The way it works is through you pulling a narrow column across a portion of the screen by dragging inwards from the right-hand edge, in line with the Home button. You then select an app, use it, and dismiss it by dragging rightwards.
Only that stopped working for me pretty quickly. No matter how I dragged, Slide Over refused to make an appearance. All I ever managed to see was the little left-facing arrow temporarily display on the screen edge, noting precisely where I should be dragging from, if my fingers had the audacity to be in slightly the wrong place.
I reasoned that Slide Over must have gotten stuck somehow. Perhaps this isn’t what happened, but it seems logical enough. One thing I did know for sure is Slide Over failed shortly after I installed and tried to use updates for a selection of newly compatible apps. So I went into the App Switcher and swiped up on every single app, in that way that sets knowledgeable tech people’s teeth on edge, given that this is something you should never have to do on iOS.
I restarted the iPad. No dice. And the apps were all back in the App Switcher anyway. So I nuked them all over again, with much gusto, opened Notes, and tried dragging from the right. I saw a ‘glitch’ of Slide Over, continued dragging, and there it was, like it had never been away.
It’s hard to know what went wrong and whether it’ll stop working again, nor whether this fix is anything but luck. (Certainly, one other person I know with this problem tried quitting all the apps and restarting, and hasn’t yet gotten Slide Over back *.) I also wonder whether a specific app was to blame, such as Pixelmator. That’s a superb iPad app — highly recommended — but it’s also extremely resource-hungry. On my iPad Air, it sometimes fails to launch, due to heavy RAM requirements. On that basis, it wouldn’t surprise me if the combination of underlying demands plus Pixelmator plus Slide Over just proved too much for the feature. But I don’t really fancy testing the theory by messing up my iPad again, when I need it to write about iPad things.
Still, now I can at least get back to complaining about Slide Over’s shortcomings, rather than it not working.
* UPDATE: I heard again from the person who the fix didn’t work for. Turns out one of the Slide Over-compatible apps had a broken download and dimmed icon but still, for some reason, appeared in Slide Over. After logging out, restarting, and logging in, the app was gone. Slide Over then worked. Clearly, there’s an issue with Slide Over getting ‘stuck’ when iOS finds things it cannot properly deal with.
