Here is a useful debugging technique:

Symptoms:
  I changed X and only X.
  Now A is broken.

action:  change X back to what it was before and see if A is broken.

That's a very basic way of determining if the changes you made caused the 
problem.

In your case, you claim that the only change is trying to run a new 
swiftscript.

So if you run an old swiftscript that worked a day or so ago, what 
happens? Do you get the error or not?

When reporting problems, its useful to try things like this first, and 
include the information about where X really does afffect A in your 
problem report email.

It makes it a lot easier for other people to think about narrowing down 
the problem.
