Enable adjustsFontForContentSizeCategory

10 Sep 2022

I wish the adjustsFontForContentSizeCategory was true by default. Instead, you need to configure it that way so elements adjust their font size as the content size category (dynamic type) changes when a preferred font is used for a given style.

Screen with the Cineaste app open. Then, the Text Size menu in Control Centre is opened and the largest font size is selected. If the .adjustFontForContentSizeCateogry property is true for the labels in the app, the app will react and increase the font size immediately without needing to close and open the app again, or pop and push the presented screen. But if it is false, the app would not change at a first glance. You'd have to pop and push the screen or close and open the app again for the new text size to take effect.

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.

If you are displaying something in two or more columns, you may want to change that to as little as one column when using some of the largest Dynamic Type settings to keep the text readable.

If you have any web views in your app (Terms and Conditions and Privacy Policy, I'm looking at you), you can also support Dynamic Type for them. You can set an Apple system font with the same styles available for native development in your CSS.

One of my favourite Dynamic Type tricks is to use Stack Views and flip the axis from horizontal to vertical given a certain content-size-category threshold. So effortless and it works so well in so many scenarios.
