Goals

Upon logging in to the Facebook app, it should return to the previous app, and the successful login callback must be invoked.

Expected results

Upon logging in to the Facebook app, it should return to the previous app, and the successful login callback must be invoked.

Actual results

When I invoked the login API of the Facebook iOS SDK, the transition to the Facebook app worked correctly. However, after logging in by selecting a profile in the Facebook app, although the Facebook app itself logged in, it did not return to the previous app, and the callback was not triggered.

Steps to reproduce

1) Prepare the Facebook app without an active login. (If already logged in, log out.) 2) Call the loginManager.logIn API with LoginConfiguration.tracking set to .enabled. 3) Transition to the Facebook app, and select the profile image within the Facebook app. 4) While the login is successful within the Facebook app, there is no transition back to the app that invoked the loginManager.logIn API, and the callback is not triggered.

Code samples & details

@IBAction func invokeLoginMethod() {
    loginManager.logIn(
        viewController: self,
        configuration: .init(permissions: [.publicProfile, .email], tracking: .enabled)
    ) { [unowned self] result in
        switch result {
        case .cancelled:
            self.presentAlert(
                title: "Cancelled",
                message: "Login attempt was cancelled"
            )
        case .failed(let error):
            self.presentAlert(for: error)
        case .success:
            self.updateLoginButton()
            self.showLoginDetails()
        }
    }
}

I also encountered this problem. Have you resolved it?

I am struggling with this as well. Any updates? I think I will route all logins through Limited Login if this issue persists.
