.toInt() removed in Swift 2?

Question

I was working on an application that used a text field and translated it into an integer. Previously my code

textField.text.toInt()  

worked. Now Swift declares this as an error and is telling me to do

textField.text!.toInt() 

and it says there is no toInt() and to try using Int(). That doesn't work either. What just happened?

Answer 1

In Swift 2.x, the .toInt() function was removed from String. In replacement, Int now has an initializer that accepts a String

Int(myString) 

In your case, you could use Int(textField.text!) insted of textField.text!.toInt()

Swift 1.x

let myString: String = "256" let myInt: Int? = myString.toInt() 

Swift 2.x, 3.x

let myString: String = "256" let myInt: Int? = Int(myString) 

Answer 2

Swift 2

let myString: NSString = "123" let myStringToInt: Int = Int(myString.intValue) 

declare your string as an object NSString and use the intValue getter
