Could you try pulling and running again?

I am having a bit of trouble running this myself from the command line. I attempted to hot fix with a solution similar to what the user annca posted here. The suggested fix is not working for me but I am interested to see if my changes will do anything on your end.

In the meantime, opening the package in Xcode allows it to function without the error.
