WgQuickConfig: Swift treats \r\n as a single character

let blah = "hello\nworld\ndoes\nthis\nwork"
print(blah.split(separator: "\n"))
//output: ["hello", "world", "does", "this", "work"]

let blah2 = "hello\r\nworld\r\ndoes\r\nthis\r\nwork"
print(blah2.split(separator: "\n"))
//output: ["hello\r\nworld\r\ndoes\r\nthis\r\nwork"]
//expected: ["hello\r", "world\r", "does\r", "this\r", "work\r"]

In blah2, the string splitting fails because swift considers \r\n to be
its own character.
