Hey Andrew :

  • Challenge :

1) Given the constant named language, write a println statement which will print the following string: "Learning Swift".

2) Use the language constant within the string you pass to your println statement. Practice using string interpolation.

Basically they want you to use string interpolation on this challenge. Remember anything that goes in between quotes, the system will take it as strings. So you want to use string interpolation, to tell the system that there is a value in there that it may NOT be of type string, so the system can retrieve that value, and display it as a string.

This is a way to do that.

let language = "Swift"
println("Learning \(language)")

In this case, the system knows now, that there is a value inside "language" and it retrieves it and displays the value as a string too.

So even if it was an integer, it will show as a String.

Hope this helps

Good luck.
