Playground Output

Hi all. I'm having a problem when it comes to playgrounds. I'm taking the App Development with Swift course (on my own), and I'm having no luck seeing the results sidebar as it pertains to the code provided as well as the code I type. I've read the long and short ways people have tried--whether it was to go to the menu bar, VO-Right Arrow to the View column, pressing VO-Down Arrow to get to the Assistant Editor submenu, then, once in that submenu, checking the Show Assistant Editor button; or the much shorter option, pressing Command-Option-Return keys to show it. The problem is that I've done both of these things, yet I cannot seem to find an output area in either case. Help would be greatly appreciated! Thanks!
