iOS Development with Swift Techdegree Student 424 PointsCannot see results of code
In my Xcode window I cannot see any results of my code in the results space. Following Xcode Help, I have gone to the Editor menu to unhide this but there is no unhide results or show results option available. What is wrong? Is my Xcode app damaged?
I cannot proceed until I sort this out. Any advice please?
Thanks
Alison

icon in the upper right, in between the ||_]
and [_||
icons. When you hover over it, it should say "Hide or show the debug area." Make sure it is blue to activate it, then it will pop up in the bottom of your XCode. Do some print statements to verify print statements are getting printed to the console. Remember, without print statements, running code usually doesn't produce any output (print statements are categorized under "IO", or "input/output").

That dumps the value inside the function (the ( and ) signs) into the console. The console is like a terminal/command line. It can take in text and output text too.
In this case, the value that is being dumped/printed in the console is the "hello world!" string, which is denoted by the quotation marks (the text in between " and ").
