Q:

Failed to instantiate the default view controller for UIMainStoryboardFile 'Main'

I am trying to create a new Swift project and am having some issues. I tried to create a new single page application but when I build I get an error saying: 
2014-06-07 11:04:13.752 Matchismo (Swift)[2007:598021] Failed to instantiate 
the default view controller for UIMainStoryboardFile 'Main' - perhaps the 
designated entry point is not set?

But when I create the same single page application project with Objective-C as the language, it compiles and runs just fine. Is there some manual thing I must do in Swift to get a project up and running?
My understanding for this error is that I need the default view to be set, which is merely checking a box on your view controller's attributes (picture below). I tried the solution suggested in this stackoverflow post but it didnt help and I can't find much more help on the subject with Swift being so new. Any suggestions are appreciated.

A:

Select the ViewController Scene. Now, select the inspector panel from the sidebar options. Check the “Is Initial View Controller” attribute option, save the project and build the project again.
