In developing OPENID / OAuth type web authentication for native apps, I am looking for confirmation that Apple iOS supports Save Password dialogue on the sign-in that occurs in the browser within the ASWebAuthenticationSession webview. Noting that both ASWebAuthentication Session and SFSafariViewController support isolated browser privacy with regards to the app, it should not (theoretically) necessitate domain trust between the App and the domain of the current AS/SF webview as it once did with wkWebViews.
Can anyone confirm that Keychain's Save Password dialogue DOES fire on either/both ASWebAuthenticationSession and SFSafariViewController?
