This occurs on an even simpler example. It doesnt seem to like:
   cond =  (st != "");


This script:

string st = "foo";
boolean cond;
cond =  (st != "");

gives:

sur$ swift tp2.swift
Could not start execution.
         Error reading source:  : unexpected character in markup > 
(position: START_TAG seen ...<argument name="value">\n\t\t 
    <>... @49:22)  :  : unexpected character in markup > (position: 
START_TAG seen ...<argument name="value">\n\t\t                 <>... 
@49:22)
