Deque University for iOS provides a series of simple examples to help sighted developers understand the implications of the iOS Accessibility APIs and how VoiceOver users are effected by poor app accessibility. In order to teach accessibility, Deque has created an app that has side by side examples of issues we see frequently in the wild. We first demonstrate how such examples can be done inaccessibly. Then we fix each, and describe why those fixes are important. The app code will soon be open sourced so that you can explore the code for each solution, so check back to the store listing frequently!
