Zoom lets the user magnify the screen if the user needs to zoom in a region to be able to see any details a bit closer. It is useful to know the gestures that let you zoom in, back out, move around the screen, adjust zoom level or show its menu.
Some of you have asked me how you can support what I do. This would really help, and would be hugely appreciated:
Find these posts useful? Share them at work, on social media, or with anyone that might find them interesting. Let's spread the word!
Check out any of my apps or games: Xarra!, RetroRapid!, or Mestre!.
A download and a review go a long way. They're free by default. On the App Store, ratings and reviews really help more people discover them.
Finding any of them useful? If so, and if you can afford it, purchasing lifetime access to all features or subscribing lets me buy the coffee that keeps me caffeinated. Caffeine keeps me going to maintain the apps, bring in new features that I hope you'll love, and keep writing.

I used to think of Zoom as an accessibility feature that didn't need support from developers. But actually, testing with Zoom might unveil some issues and bad practices. Watch out for buttons that change something far away on the screen. Using a snackbar is usually not a good idea. Especially if it lets you do/undo something. Because they're ephemeral, they're difficult to spot and/or reach with Zoom, VoiceOver, Switch, Keyboard... Confirming a destructive action with a dialog might be better.
If, for some reason, you are creating a button from scratch, instead of relying on UIButton (perhaps you are adding a fancy micro interaction animation?), take into account that you’ll need to configure the button accessibility trait.
Toggles or UISwitches are often found separated from the label that precedes (and describes) them; with an unclear label; missing a value, trait, or hint; or even not being actionable at all.
