I'm using Xcode 7 Beta 3 and reading through Swift 2.2 document. I'm trying to compile this example found in the Basics section of the document:
let possibleNumber = "123"
let convertedNumber = Int(possibleNumber)
It is supposed to convert a string into an optional int. However Xcode gives the error:
Cannot call value of non-function type 'int'
I was working on Xcode 7.2.1, then I knew that Swift 2.2 is packaged with Xcode 7.3 Beta 3, so I downloaded that to try, but the same error happens.
So, is the document wrong? and how to achieve the string into int conversion?
