You added an extra space. The \ has to be up against the (. Just as a note, the \ is used to escape characters, that is why you got an invalid escape error, \ + space is not a valid escape sequence.

var str : String = "Learning "

let language: String = "Swift"

var greeting = "\(str) + \(language)" 


println("Learning  \(language)")
