Worked on the Telefonica/mistica-ios repository to enhance the accessibility of the Button component by implementing font size adaptation that respects both dynamic type and user accessibility settings. Utilized Swift and iOS development skills to update the component so that it automatically adjusts its font size in response to changes in the UI environment, specifically by leveraging traitCollectionDidChange to reapply the correct font style. This approach ensures consistent accessibility fidelity and usability for users with varying needs. The work focused on inclusive UI development, aligning the component with accessibility standards and improving the overall user experience across iOS applications.
