Can't call user summary after auth

[emreond]

Hello,

I am trying to get user summary after authenticate with WebView. Webview is opening without any error and I am typing my pass and then It stucks at white screen and It doesn't get into userSummary calls completion blocks.

P.S: Authenticator succesfully returns secret.

                Authenticator.keychain
                .visual(filling: self.webView)
                .authenticate()
                .sink(receiveCompletion: { _ in }, receiveValue: { secret in
                     debugPrint("It succesfully returns secret")
                    Endpoint.user(secret.identifier)
                        .summary
                        .unlock(with: secret)
                        .session(.instagram)
                        .sink(receiveCompletion: { subscriber in
                            debugPrint(subscriber)
                          ....
                        }, receiveValue: { [weak self] user in
                            guard let user = user.user else { return }
                            ....
                        })
                        .store(in: &bin)
                })
                .store(in: &bin)

Hey @emreond,
are you perhaps on Xcode 13? Authenticator.keychain does not currently work with Xcode 13 (the dependency hasn't been updated to fix it yet, unfortunately).

Otherwise do you mind telling me a bit more? Does the Secret receiveValue actually get called? Are you making sure you're retaining bin?

[emreond]

Nope I am on Xcode 12.5. Authenticator successfully returns secret. Therefore, I suppose, endpoint is get called but noting returns even with .session(.ephemeral, retries: 1, logging: .default) . I assigned bin inside function just above DispatchQueue maybe It is because of that, I will try to make it global.

It's probably because you're using Combine Publisher's wrong, then.
Try this, instead:

Authenticator.keychain
    .visual(filling: self.webView)
    .authenticate()
    .flatMap { secret in
        Endpoint.user(secret.identifier)
            .summary
            .unlock(with: secret)
            .session(.instagram)
    }
    .sink { _ in
    } receiveValue: {
        guard let user = $0.user else { return }
        print(user)
    }
    .store(in: &bin)

Keep in mind this flow, when you immediately rely on the logged in Secret to drive an Endpoint, is not ideal.

If this does not work still, then it's because bin is not retained correctly and it's deallocated before it can actually publish an output.
Please refer to Combine tutorials and documentation to learn more as this is not an issue related with Swiftagram.

This is working like a charm. I am not used to Combine , I need to check more. Thank u so much.
