Rxswift: playground does not work in swift 4

[SNThunderbolt]

hi
I'm trying to use rx.playground. I built the rxSwift-macOS successfully
but when I go to rx playground the debug area shows nothing! I tried using TryYourself.playground still
nothing, I commented out everything and just printed "hi" but nothing seems to work.
could anyone help me please?

I'm using Xcode 9.3 and macOS HighSierra.

Keep it simple by think out of the box.
Create a sample project (not playground).
Declare function & variable as normal then it's work like a charm.

import RxSwift

func example(of description: String, completion: () -> ()) {
print("--- Example of: (description) ---")
completion()
}
class ViewController: UIViewController {
let one = 1
let two = 2
let three = 3

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    let observable1: Observable<Int> = Observable<Int>.just(one)
    let observable2 = Observable.of(one, two, three)
    let observable3 = Observable.of([one, two, three])
    let observable4 = Observable.from([one, two, three])

    example(of: "subscribe") {
        observable2.subscribe { (event) in
            print(event)

            if let element = event.element {
                print(element)
            }
        }
    }
}

}
