When the following error occurs in Titanium Mobile, it’s caused by a JavaScript syntax error.

[ERROR] Script Error = Parse error (unknown file) Terminating app due to uncaught exception of class '__NSCFDictionary' terminate called throwing an exception

Check if the code you recently modified is syntactically correct JavaScript.

That’s all.
