[Swift-user] readData is treating line as a single field

[Ketan Maheshwari]

I found that the problem was a misplaced space in one of the paths in my
original file used for the run. Removing the space fixed the issue.

While trying to debug/reproduce, I found that readData() works with tabs,
multiple spaces, combination of tabs and spaces and irregular number of
spaces between fields.
