Here are the steps I took.
Type "vapor new Hello" and then "y" in terminal.
In Xcode, when I clicked run, it builds but doesn't run. Debug console is empty.
When I executed "vapor build" and "vapor run" in the terminal, it runs though.
I have Xcode 8.3.2, Swift 3.1, Vapor Toolbox 2.0.3, Vapor Framework 2.0.0.
Thanks!
@jsl303 Can you confirm that you selected "Run" see the attached image for an example.

Thanks!!! That was what was missing! I don't remember ever checking run
from the Scheme for my IOS/OSX projects. Maybe it's checked by default
for those.
Would you be able to add the instruction to Xcode part of the
documentation for beginners?
Thanks again!
@tanner0101 @jsl303 Brings up a good point. We may want to add this to the documentation for beginners.
@Aaron-A great suggestion, submitted a PR to documentation 馃憤
