Return function and string

Yes that what I did too sorry but I cannot get still have an issue

func greeting(person: String) -> String { return person }

println("hello (greeting("tom"))")

I also try with

func greeting(person: String) -> String { return person }

println("hello (greeting(tom))")

And also try

func greeting(person: String) -> String { return "tom" }

println("hello (greeting(tom))")

Can some one give me the correct answer for this exercices "Function return type" in Swift Functions and Optionals courses

Thank you

You forgot the / for string interpolation. "Hello /(greeting...

The solution was like this, finded my answer.

func greeting(#personName: String) -> String { let greetings = "Hello, " + personName + "!" return greetings }

println(greeting(personName: "Kevin"))
