Sometimes we may fail to convey to the user of things changing on the screen in a perceivable way. Toasts and similar should be announced. We may want to make clear that some content on the screen changed. Or we might want to update on progress.

Sometimes we may fail to convey to the user of things changing on the screen in a perceivable way. Toasts and similar should be announced. We may want to make clear that some content on the screen changed. Or we might want to update on progress.

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.

@azzoor is the developer of the Braille Scanner It uses computer vision to locate the page and Machine Learning to match Braille to letters. You can see English letters above the braille, convert them to speech, copy and paste it... so cool!

You should convey important information in multiple modes, not just color. If you are still required to do so, at the very least you should complement that info with other modes, like symbols, if the user requested differentiation without color.

Since iOS 14, you can get a human readable localised name for a UIColor, with a very useful property called accessibilityName, that you can use in accessibility attributes like labels or values. How cool is that? https://developer.apple.com/documentation/uikit/uicolor/accessibilityname
