Strings and arrays

I don't know whats wrong with my code. Can anyone solve this ? This is what te console said: The favoriteSports variable was expected to be a array of strings (aka [String]), but it wasn't.

let bestSmartphone = "iPhone" 
var favoriteSports: String = "football"

It should look like this:

let bestSmartphone = "iPhone"
var favoriteSports = ["football", "basketball", "tennis"]
favoriteSports.append("volleyball")

Thank you verry much !

let bestSmartphone = "iPhone" 
var favoriteSports = ["football", "basketball", "baseball"]

An array is encased in []

What you wrote is:

var favoriteSports: String = "football" 

This just means that you want favorite sports array to be a explicative type of string with the value being football. In english what you said is "My favorite sports are football." Hope this helps.

I was doing this:

var favoriteSports = ["football","basketball","tennis"]
println ("\(favoriteSports), volleyball")

Yeah that works, it will add volleyball to the array, but why not .append it to the array(well mutable array)?
