Using Int, combined with a String to print existing String

newbie programmer here, can't figure out why it does it...

let a1 = "This is some text"
let x : Int = 1

var stringValue = "a\(x)"

print(stringValue)

I want it to print "This is some text", but it only ever prints a1.

Rather than storing 'This is some text' in a1 string, save it in a dictionary so you can create the key (x1,x2 etc) to access it:

let stringDictionary = ["a1": "This is some text", "a2": "This is more text"]

You can then pull it out using:

let x : Int = 1
let stringKey = "a\(x)"
let stringValue = stringDictionary[stringKey]
print(stringValue)

What you want is an eval or evaluate type function, but that doesn't exist. What you're actually getting is a description of the x variable, which is the number 1 converted into text, hence a1.

If you want to get a value for a key you should use a dictionary.
