First Where Violation when using filter first #254

So I have this slightly redacted piece of code:

self.webSocketHandler.isConnected.filter { $0 }.first().observeNext { _ in }

It's giving me the following warning (not sure if it's SwiftLint or vanilla Xcode though...):

First Where Violation: Prefer using .first(where:)over.filter { }.first in collections. (first_where)

However the first(where:) method doesn't seem to exist in that context.

It's not a big issue and perhaps I'm overlooking a better way to do it but it would be nice if it would actually have first(where:)
