Convert CGFloat to NSNumber in Swift
18,112
Solution 1
In Swift 3.0
let myFloat : CGFloat = 1234.5
let myNumber = NSNumber(value: Float(myFloat))
or
let myNumber = NSNumber(value: Double(myFloat))
In Swift 2
let myNumber = NSNumber(double: myFloat.native)
or
let myNumber = NSNumber(double: Double(myFloat))
or
let myNumber = NSNumber(float: Float(myFloat))
Solution 2
For Swift 3.1
var final_price: CGFloat = 12.34
let num = final_price as NSNumber
Solution 3
Swift 3
let myNumber = NSNumber(value: Float(myCGFloat))
Solution 4
For me this is worked.
self.configuration.cellHeight as NSNumber!
Solution 5
You can access a CGFloat's NativeType
via the native
property:
public var native: CGFloat.NativeType
The native type used to store the CGFloat, which is Float on 32-bit architectures and Double on 64-bit architectures.
With this you can create an NSNumber
like so:
NSNumber(value: cgFloat.native)

I have an extension in Swift that holds some properties which are
CGFloat
's. The problem is that I don't know how to get the store theCGFloat
value as aNSNumber
using the associated objectsHere is the code I have that doesn't work but it details what I want to do:
var scaledFontSize: CGFloat { get { guard let fontSize = objc_getAssociatedObject(self, &AssociatedKeys.scaledFontSize) as? NSNumber else { //Set it let scaledFont:CGFloat = VGSizeValues.getValueFromValue(self.font.pointSize); //Fails here objc_setAssociatedObject(self,&AssociatedKeys.scaledFontSize, NSNumber( scaledFont),objc_AssociationPolicy.OBJC_ASSOCIATION_RETAIN_NONATOMIC) return scaledFont; } return CGFloat(fontSize.doubleValue); } }
Does anyone way to work around this?
