xcode 7.2.1 and playgrounds
I am having issues with Xcode playgrounds.
I created a playground, and specified mac os x for the target.
In the editor I typed in the line of code:
print("this is a test.")
Now, I did cmd+opt+return to bring up the assistant editor to review the output.
I then vo+right to the asst. editor, and it doesn't show my output.
I get one of two outputs:
1. it shows a copy of my code from the source code editor.
2. It is fully empty.
so, what am I doing wrong?
Am I supposed to hit a command to run the code so the output shows up in the assistant editor?
Any help would be greatly appreciated.
