Courses Plus Student 196 Pointsprintln does not work: why? not in Xcode either. let language = "Swift" println("Learning",language)
Using Treehouse course "iOS, i have problems:
println does not work: why? not in Xcode either.
let language = "Swift" println("Learning",language) // should say "Learning Swift" // doesn't
// above is Treehouse Teacher // below is Xcode, on mac
let language = "Swift" // shows: "Swift\n" print(language) // shows: "Swift\n" print("Learning",language) //shows: "Learning Swift\n" println("Learning",language) //shows: ERROR 'println' has been renamed to'print"
So, println is NOT right?
Is there no way to use this course? or is there something useful online?
\Thanks, Shelli
let language = "Swift"
println("Learning",language)

You need to use String Interpolation to add the value associated with the variable into the string literal. You do this by writing \() and placing the variable name inside of the parentheses.
let language = "Swift"
println("Learning \(language)")
Good Luck!

7,806 Pointsin Swift 2.0 the println has been renamed to print. when you use print() xcode will print whatever you add in between the parenthesis and finishes up with a new line "\n" so if you do:
print("Swift Course") the result will be Swift Course\n
