Day 172

It is not just about applying accessibility APIs, but about caring, and thinking of features that can make your app more accessible and inclusive to everyone. Twitter's alt-text feature is a great example. Thanks, @TwitterA11y! You'll be missed.

When composing a tweet, and adding an image, there is a button that lets you add some alt text to it. On a separate screen, you'll be able to write up to 1000 characters. There is a link to find some help on how to write alt text. After publishing a tweet with an image with alt text, an ALT badge will be shown at the bottom left corner of the image and tapping it, it opens a modal view with the alt text configured.

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.

When implementing a UISlider, it is a good idea to consider how much the slider value should change when swiping up/down to adjust it. It might not always make sense to do it in 10% increments, which is the default behaviour. Could be because the value at those intervals doesn't make sense, or feel random, or because it wouldn't provide the user with a fine enough control being able to go through the whole slider in just 10 swipes. It user will still be able to adjust the slider to any value by double tapping and holding and then moving the finger left or right, bypassing VoiceOver gestures. VoiceOver announces the new value as it changes.

Day 141

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.

Day 51

Guidelines from Apple: Begin with a verb that explains the results of the action. Avoid using the imperative form of a verb because that can make it sound like a command. Don’t include the action type. Don’t include the control. https://developer.apple.com/documentation/objectivec/nsobject-swift.class/accessibilityhint
