Cannot play video using SKVideoNode but sound is audible

Question

While I am testing this app Xcode Simulator, I am unable to see video in SKVideoNode but the sound is audible.

The same issue for both .mp4 and .mov files

func showVideo() 
{  

        let strVideoFile = "Beach.mov"
        let spriteVideo : SKVideoNode = SKVideoNode(fileNamed: strVideoFile)
        spriteVideo.position = CGPoint(x: 0, y: 0)
        spriteVideo.setScale(0.5)
        spriteVideo.zPosition = 10
        spriteVideo.alpha = 1.0
        self.addChild(spriteVideo)
        spriteVideo.play()
        print("Playing \(strVideoFile)")

    }

No error messages displayed. I know that the node is added because I can see the increase in the node count.
