I saw this sentence in the documentation at https://developer.apple.com/documentation/bundleresources/information_property_list/nsrequirescertificatetransparency: 'Don’t use this key. The current system enforces this behavior, and new certificates can’t meet the requirement on older systems.' I understand that new systems will enable CT (Certificate Transparency) verification by default. However, I created a new demo to verify this on an iOS 13 device, and CT verification was not actually enabled.
