string is not convertible to int (Swift)

Question

This is the code I have (my actual code is more complex, but I simplified it down, and I still get this error):

let x = "1" as Int

Xcode says:

'String' is not convertible to 'Int'

Am I missing something or is this a beta bug?

Answer 1

You cannot simply cast with as. There is a method that produces Int explicitly.

let x = "1".toInt()

Notice that the result is of type Int? because Swift cannot know upfront if the conversion succeeds.

println(x!)

Or:

let x = "1".toInt()!
