After putting some operators on a publisher I am curious as to what the current return value and/or error is. Is there a quick way in Xcode that you can check that?

I would like to see something like Map<CombineLatest<Published<String>, Published<String>, String?>>.

I know I don't need to know if I erase it with .eraseToAnyPublisher, but I like to check.

An easy way is to insert the line

.map{$0}

– which practically does nothing – and ⌥-click on $0
