Hi Folks, I am reaching out for an iOS A11y color contrast issue, which I have also fired a bug report 12525894 but does not get any reply.
The UIAlertAction in destructive style has a poor color contrast ratio of less than 4.5: 1 between text color and background color. This applies to any system/third party app which uses UIAlertViewController from UIKit and Alert from SwiftUI (Take the system Photos app as an example). Given that the "titleTextColor" property from UIAlertAction class is private, developers have no ways to modify the alert action to make it WCAG compatible.
Here is an example of the Photo app alert. The text "Delete Photo" (#EB4E3D) should have a contrast ratio of at least 4.5 to 1 against its background(#EAEBE7) to comply to the Web Content Accessibility Guidelines (WCAG).
Actual result: The text "Delete Photo" (#EB4E3D) has a contrast ratio of 3.08 to 1 against its background(#EAEBE7), which does not match 4.5:1 Web Content Accessibility Guidelines (WCAG).
