In some more detail:
- We know that using accessibility services features described at
https://developer.apple.com/documentation/accessibility/
https://developer.apple.com/documentation/uikit/accessibility_for_uikit
- One can develop an application more accessible to users who are blind or have low vision.
- We have experience in developing iOS apps using UIKIt and SwiftUI
- We are developing screen reader applications since 2014, and we have experience in developing screen reader-like applications for Android, similar to Talkback.
- We want to experiment with doing the same for iOS eventually replicating some of the VoiceOver features
Therefore the more detailed question for us is:
Is there any API for programmatically accessing accessibility features exposed by a running third party iOS application compliant with UIAccessibility specifications?
For instance, Whatsapp is the foreground running application, I want to access its UI Element features (namely the UI accessibility features). Is it possible? If yes, which API or SDK can I use?
