I'm stuck on this code challenge. See code below:

I thought I formatted the interpolation correctly

// Enter your code below
let name = "Nate Drexler" 

let greeting = "\(Hi there,) \(name.)"

Hey Nate,

There are a couple issues going on here.

  • You can not interpolate a string. Only variables / constants can be interpolated, so "Hi There," should not be enclosed in parenthesis.

  • The period needed cannot be added inside of a interpolated variable. You can add this two ways: After the closing parenthesis for the name variable but before the closing quote. Or just add in to the end of the value assigned to the name variable (I chose the latter).

Other than that... looks good. Below is the corrected code for you to reference. I hope it makes sense.

let name = "Nate Drexler." 

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