Concise Swift assertion for Bool? || Bool?

Can I formulate a concise expression in Swift for asserting that the activity indicator of one of two view controllers is animating. The expression may assume that either

vc1
or
vc2
is distinct from
nil
.

The following does not quite work, presumably because it is of the form
Bool? || Bool?
instead of
Bool || Bool
:

assert(vc1?.activityIndicator.isAnimating ||
v22?.activityIndicator.isAnimating)

Answer

== still works for optionals, so you could do something like this:

assert(vc1?.activityIndicator.isAnimating == true ||
       v22?.activityIndicator.isAnimating == true)
