Swift and XCode 6 - Converting Integer to String

Question

I have an Xcode project with a label and a UIAction button. Upon tapping the button, I want the value displayed in the label to increase by 1. The problem is that I can't display the variable "value" in the label, because it's an integer, and the label takes a String data type. Here is the code I have so far:

var value = 0 

@IBOutlet var label: UILabel!

@IBAction func button(sender: AnyObject) {
    value = value + 1
    label.text = value
}

label.text = String(value)

Or

label.text = "\(value)"

Or

label.text = value.description

Which do you use most? .description or String() – spencer.sm Mar 12 '16 at 07:04
In Swift 3 ` String(describing: value)` is preferred – Tim Oct 18 '16 at 05:34

@LinhChu String(describing: ) may return "Optional(intValue)" as the string while .description does not – Charlton Provatas Oct 26 '16 at 17:42

Of course I would save some typing and express it this way:

value++ 
label.text = value.description

In the end it is the same thing as:

value = value + 1
label.text = value.description

you can convert value before saving core data directly just like that

//core data 
userid value = string

we need to store Int value we have to convert the value explicitly like that. I tried that and it works fine core data contain task entity having user_id attribute

 tasksEntity.user_id = string

that should work
