In certain circumstances, the App SDK displays a screen to allow the end user to pick an account. This happens when the user has registered an authenticator for multiple accounts.
An example of how to replace the user selection screen is in SampleUserSelectionUI in the Tutorial App. This example silently selects the first account instead of prompting the user. To test replacement of the user selection UI, uncomment the following code in the AppDelegate.swift file of Tutorial App as shown below.
SampleUserSelectionUI.replace()See the Client API Docs for more information on the specific APIs.
