To check the session status in theiOS Swift SDK, you should use thegigya.isSessionAlive()method. This method determines whether the current session is active and valid.
* Option A: Correct. Thegigya.isSessionAlive()method checks if the session is still valid by verifying the session token and its expiration time.
* Option B: Incorrect. Thegigya.isLoggedIn()method checks if the user is logged in but does not verify the session's validity.
* Option C: Incorrect.gigya.sessionExpirationTimestampprovides the timestamp of when the session expires but does not actively check the session status.
* Option D: Incorrect.gigya.sharedInstance().sessionExpirationTimestampis similar to Option C and only provides the expiration timestamp without verifying the session.
