42,016 Pointsyou need to put a space after learning and use \ to interpolate the language variable, not /
let language = "Swift"
// include a space
println ("Learning \(language)")
interpolation uses a backslash
the reason you include a space after Learning is so the output is "Learning Swift" and not "LearningSwift"
see the Swift eBook for more information on 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:
