Swift debugging driving me nuts. #helpMe

I have a multiline file that I’ve loaded into a string using String(contentsOfFile:encoding:)

I'm trying to split the string using “someString.components(separatedBy: "==========\n“)

But it... just doesn’t. I know that particular string does exist in the file multiple times.

If I change the separator to just a linefeed it does split the file into 1600 items just fine. So for some reason it's not finding the "==========\n“ ?

I'm stumped.
