title: Xcode 10 playground is not showing the output
body: <p>I am using Xcode 10 on macOS Mojave 10.14.4. When I open the playground I am unable to get the output window to output anything, even using the print command it stays blank. Is there any other program for mac that shows output as you code in swift? Or has anyone encountered and was able to fix this problem?</p>
