Convert a double to NSNumber in Swift

Question

How do I convert a double to NSNumber in Swift?

I tried

let myDouble = 7.12
NSNumber(myDouble)

But got the error:

Argument labels '(_:)' do not match any available overloads

Answer 1

Use init(value:)

let nsNumber = NSNumber(value: myDouble)

or simply a cast

let nsNumber = myDouble as NSNumber
