David Marin Calleja enhanced accessibility in the Feedback component of the Telefonica/mistica-ios repository by implementing missing accessibilityTraits for the header label and various button types. Working in Swift and focusing on iOS development, David addressed gaps in screen reader support, ensuring that users relying on assistive technologies receive accurate feedback and navigation cues. The work involved careful analysis of accessibility requirements and integration of best practices to improve compliance. Although the project scope was limited to a single feature over one month, the changes provided a targeted solution that improved the overall accessibility and usability of the Feedback view for all users.
