Where is the "screen time" API documentation? I've found interfaces in the frameworks themselves with little documentation but the web doesn't provide any helpful documentation, examples, or guidelines to leverage the new APIs.

Mozilla employs encrypted DNS now in browsers. If in the case such DNS cannot be used, maybe users need corporate DNS for example, a "canary domain" can be resolved first and if it is successful, encrypted DNS is used by the application. However, if is is unresolved with a known and expected DNS error response, encrypted DNS is not used. Does Apple have or plan to have a "canary domain" that would allow a VPN on device to "notify" the system a per-app encrypted DNS usage is not allowed? How does Apple plan on allowing a user on a corporate network to access everything needed on their own DNS without forcibly adopting a per-app encrypted DNS usage? Thank you, Logan
