AWSMobileClient initialise returns user-state "SignedIn" after uninstalling and then installing application

Question

I am using aws-cognito UserPool (via. AWSMobileClient) for authentication of users to access the AWS Services. Currently the user may choose to log-in via Phone, Google and Facebook using Hosted UI option, which requires to initialise the AWSMobileClient, via. AWSMobileClient.default().initialize(<#T##completionHandler: (UserState?, Error?) -> Void##(UserState?, Error?) -> Void#>) Which returns me the current user state.

Use Case : I sign in to my application via UserPool, and the uninstall the application. When reinstalling the application I fetch the current user state, it returns as “Signed-In”.

How may I stop this behaviour?

Answer 1

The "problem" is that AWS SDK stores the login information in the keychain, and this information is not deleted when the app is uninstalled.

Solution is to perform a signout in the first access of the user to the app. Use a Bool in UserDefaults to know if it is the first access.
