Hey there!

In order for this to work, the code would have to be the following:

let name = "Erik";
let greeting = "Hi there, \(name)"

Only the dynamic part, in this case the variable name, has to be wrapped in \(). All static text works just like a regular string, like:

let variable = "variable"
let anotherVariable = "another variable"

let text = "This is a static part. This prints out a \(variable) and \(anotherVariable). See?"

Make sure to have a look at Apple Docs: String Interpolation for a more in-depth explanation.

Hope that helps :)
