Swift code:

func debug<T>(..., statement: () throws -> T) rethrows {
  let result = try statement()
  ...
  return result
}

It should compile away in optimized builds.

It's "conditional conformances". We intended to implement it in Swift 4 and didn't quite finish. It'll probably be in 4.1.

Also stop making things optional for no reason.

Yeah, you can still do it with optionals, it just turns it from usa.states.flatMap { $0.cities } into something a little more complex/obscure.

But you should also be able to just declare the properties to be nonnull. IIRC, if you do that the bridging logic will automatically turn an unexpected nil return into an empty array.
