Can't initialize TWTRAPIClient

[intersect_haad]

Hi All,
I’m attempting to intialize the TWTRAPIClient to perform a client request.
When I attempt to initialize it with the following: TWTRAPIClient(userID: userID)

I receive the error:
[TwitterKit] initWithSessionStore:userID: Invalid parameter not satisfying: sessionStore

Any thoughts why? I’ve successfully logged in and authenticated the user.

Thanks.
