TWTRTwitter sessionStore now returns TWTRAuthSession: so how does one access the userName property now?

问题

With TwitterKit 3.3.0 in Swift sharedInstance().sessionStore.session() now returns a TWTRAuthSession rather than a TWTRSession, as before. Things change, that's fine, however the documentation hasn't been updated to reflect this, and as such I no longer know how to access the userName property that the former TWTRSession object offered.

回答1:

You can do this with perform(_:)

Hope below will help those who face this.

let username = session.perform(#selector(getter: TWTRSession.userName))?.takeRetainedValue() as? String
