Are you referring to this:
println("\(distance)....")
If so... the syntax you see there is called String Interpolation.
String interpolation is a way to construct a new String value from a mix of constants, variables, literals, and expressions by including their values inside a string literal. Each item that you insert into the string literal is wrapped in a pair of parentheses, prefixed by a backslash.
Check out "The Swift Programming Language" from Apple for additional documentation.
I hope this helps!
