iOS Swift 2.0 Basics Swift Types String Manipulation

Interpolated greeting. My attempt is let greeting = "\(Hi There),\(name)" I don't understand my error

let name = "Alexis" let greeting = "(Hi There),(name)"

or is it

let name = "Alexis"

let greeting = "Hi there"

let interpolatedGreeting = "(greeting),(name)"

I'm confused about what I'm doing wrong here.

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

Don't overthink it. Try this

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

When you try to interpolate (Hi + there), it is looking for a variable called "Hi + there".

Also, your second example would technically work (with one minor tweak), but it is unnecessary to create the "greeting" variable in this example. If the greeting would be reused or a more complicated string, I would maybe use a variable, but in this case its fine.

Oh I see! Thank you!
