I recommend running your app with Double-length Pseudolanguage. It is a great way to stress-testing your app and see how adaptive it is and if your UI will hold to other languages that might be a bit more verbose or even with larger text sizes.

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.

Reminder to enable Larger Accessibility Sizes, so you can pick from one of the five extra accessibility sizes when configuring text sizes. You can do it from Settings, Accessibility, Display & Text Size, and Larger Text.

You don't have to offer an alternative layout just for the accessibility category. You can actually compare content size categories. So you could tweak the UI already for anything equal to or larger than .extraExtraLarge, for example.

Color contrast between text and background is very important for perceivability. As colors come closer to each other, they’re more difficult to distinguish. Notice that colors that work well with big font sizes may not for smaller text.
