Can you validate whether a user has been recently authenticated on Firebase (Swift)?

Is there a way to check if a user has recently authenticated on Firebase to avoid this message when trying to delete a user: "This operation is sensitive and requires recent authentication. Log in again before retrying this request."

I have been playing around trying to compare lastSignInDate (below) to current time but there seems to be a large margin of error on this which can cause problems:

firebase.auth().currentUser.metadata.lastSignInTime

Are there any functions that can return a simple boolean as to whether a user has recently authenticated so the user.delete() function will work properly?

Thanks so much!

The best way to do this is by checking if the response has an error, like so:

let user = Auth.auth().currentUser
user.delete { error in
  if let error = error {
    if (error.code == "auth/requires-recent-login") {
      // The user's credentials are too old. Prompt Login screen.
    }
  } else {
    // ...
  }
}

According to Firebase Documentation, There's no other approach to this other than comparing the current date with firebase.auth().currentUser.metadata.lastSignInDate (Only if you have the Admin SDK on your app, but you most probably do not need that for enabling a user to delete themselves).
