Hi, In our app we use WKWebview to log in and want to handle webcredentials. For that purpose we're trying to create a PoC using website that's not public and is accessible only behind VPN. The physical iPhone has enabled Developer mode and Associated Domains Development switched to on. Following the documentation, I Added the associated domains capability with ?mode=developer suffix and the domain of that website However, when I run my app on physical iPhone in Debug mode with developer certificate, the autofilling prompt doesn't show up. When checking device logs for swcd logs, I can see entries connected with my associated domain, which looks like this: Entry { s = webcredentials, a = <app id>, d = ko….ge….pl?mode=developer, ua = unspecified, sa = unspecified } needs its JSON updated because the app PI changed Further I can see also entries like this Request for '<private>' denied due to HTTP status 404 on route .wk for task AASA-D9B9E2C0-F657-4DA5-B2D1-487D6775766F { domain: ko….ge….pl?mode=developer, bytes: 0, route: .wk } Which seems justified, because the site is not public, thus that's why we add ?mode=developerat the end to webcredentials entitlement. When we open the same website in Safari, the autofilling works flawlessly, so we exclude the problem with html. How can I further debug the problem?
