i have a question, i auth my user with AuthentificationServices but at disconnect, i don't know how to flush the session previously saved, if a user clic on reconnect right back, it will be connected with the previous account that made the disconnection
do you have an idea ?
ASWebAuthenticationSessiondoesn't maintain your session itself, but it does use session stored in Safari. See this section in the docs:So if you're authenticating to an OAuth service/app and that service maintains a user's session in Safari then you might see it auto-authenticate you without having to re-enter a username/password. This is only an issue if you want to support multiple logins for a single device - more likely to be an issue during your testing than in normal use (in my experience).
iOS let's users opt-out of the auto-login using previous session each time it tries to authenticate them with the previous session, but I'm not sure of an easy way to flush their session on behalf of them every time you try to do an OAuth from your app.
Hope that helps!
Thank you for your kind and detailed answer,
Indeed, maybe my wish to fully disconnect after logout is related to my dev role and I would find this annoying as a user.
I’m still curious if there is a possibility or if it’s intended in the design of ASWebAuthenticationSession
You could try prefersEphemeralWebBrowserSession, a new feature in iOS 13, to at least block your web view from sharing session with Safari and be a bit more explicit about making your user login. I'm not sure it speaks to your specific issue, but might be worth exploring.
Ran into the same issue, what we ended up doing, was instead launching a clear session url which auto redirects to the login each time.
Hi,
Is there a way to set the modalpresentationstyle to Fullscreen for the aswebauthenticationsession controller?
There might be a way to enforce that for your entire application by writing an extension or swizzling, but I don't think you can set it on the ASWebAuthenticationSession provided modal. Hope that helps.
Same here, I'm having issues getting an auth code for the callbackURL. The crazy thing is that the ASWebAuthSession's callback doesn't execute. I've given it a valid url and callbackURLScheme.
Hello, I have the same problem, have you found a solution?
Hi, I'm having trouble to get the call back in completion handler once response back from the API. can you help me pls?
Hello, I have the same problem, have you found a solution?
I tried ASWebAuthenticationSession mentioned in the above example, the callback handler is not being called. Hence, the web view doesn't dismiss after the authentication is complete.
The same thing I tried with WKWebView. It works fine.
Could you please help me with this?
If you're being authenticated but not routed back it sounds like it could be an issue with the callback URL? Just an initial thought, make sure your callbackUrlScheme is correct.
Hello, I have the same problem, have you found a solution?
I am trying to use the Ecobee API, but they want you to use a HTTPS prefixed URL for the callback scheme... "example.com:/auth".
When I try to get the auth token I can login and authorize my app, but it always ends with "cannot find the server..." and all I can do is cancel.
On GitHub (for using the GitHub API) you create an OAuth App that will accept the callback URL scheme and act as your auth server, by handling callbacks and returning a token for access. That's what I did for my implementation. See if Ecobee has a similar setup, otherwise you might have to implement your own auth server.
I have a question, after successful authentication, the redirect_URI (universal link) is handle by the SceneDelegate Class and don't go back to my initial view controller!
The sign-in screen never dismiss because completionHandler is never called on success.
Do you have an idea or a sample Xcode Project?
@rosatp Were you able to get this working?
@ajkueterman,
i have implemented the ASWebAuthenticationSession as you said in example but somehow its not working, could you please share the sample project to login OAuth.
Thanks in advance.
Unfortunately I don't have any open source apps that are using the modern ASWebAuthenticationSession flow. I'll see if I can't put something together soon, but for now if you have specific questions I can try to help.
