I am writing var str = "Hello, Playground" and it doesn't show on the right column.
the commands I write don't reproduce to the right of the of the screen.

On the top right corner of the Xcode window, there is a little symbol that looks like two circles. If you hover your cursor over it, it reads, "Show the Assistant Editor". Click on it. And then, on the left side of the Xcode window, click on the icon that looks like a play button next to your line of code. Then it will display the result of your code like it does in teacher's video. Code results do not automatically show by default when you first install Xcode. You have to manually configure your way so that it displays on your Xcode.
I suggest you reinstall Xcode.

If it was your first time opening Xcode it'll take some time to load, give some time like a minute or two.

I am also having this problem. Have reinstalled twice. In the top bar it does say "Launching Simulator" but it has been saying that for at least 30 minutes now with no change. Any suggestions?
For those using Xcode 10.2.1 whose results do not show on the right-hand side as in the video.. select:
The overlapping circles in the top right hand corner of xcode (an empty box should pop up)
Then select Live View (located right underneath the overlapping circles)
Then click the play button on the left-hand side of your code (indicated by the triangle inside the circle)
NOTE: Xcode should now print "Hello Playground" NOTE: Have not figured it out yet, but it appears you have to do this with each new file you create.
