converting an element of an array to a separate String

So I have this problem where I can't convert an element of my array to a string

I have a string like this

var description:[String] =["blue","yellow","red"]

and I want to give one element of my array to another variable which is chosen by another integer like this

var pick:[Int] = 2 var chosen:[String] = description[pick]

it says Cannot assign value of type 'String' to type '[String]' and to fix it xcode suggests to do it like this 

var chosen:[String] = [description[pick]]

now if I want to cast this variable to another one or give it to a function or whatever it will say Cannot assign value of type 'String' to type '[[String]]' please help.

Is required for variable chosen to be an array? Otherwise you could just: 

var chosen: String = description[pick]

You are getting very confused here...

First...

var array = ["red", "yellow"]

Is an array of strings. Don't call it description. Call things what they are.

Second...

var pick: [Int]

Is declaring an array. Setting it = 2 doesn't make sense.

Change your last line to...

var chosen: String = array[pick]

In the above line using [String] here is telling the system that you are getting an array of Strings. You're not. You're getting a String here.
