In your greeting constant you have Hi there wrapped with a (). When you wrap something with () it tells the complier to interpolate whatever is inside there, or pull the value out of whatever it is referencing, essentially. Hi there can't be interpolated because it isn't referencing anything, the complier doesn't know what that is. What you want to do is just put your string "Hi there" and then an object to interpolate. So it would need to look like this.

// Enter your code below
let name = "Aditya"
let greeting = "Hi there,  \(name)."

Does this make sense?
