Swift doesn’t have an equivalent because the language simply isn’t as dynamic as Objective-C: there is no mechanism to invoke a method at runtime given its name.

If you’re on an Apple platform, and the method you want to call, and its class, are @objc — then you can literally use NSInvocation from Swift to do this. But not otherwise.
