NSPNGFileType - not found in Swift?

Question

Today, I found something strange :

I wanted to write this code in swift :

    NSData *data = [myImage representationUsingType: NSPNGFileType properties: nil];

In swift it's look like this:

var data: NSData = imageToSave?.representationUsingType( NSPNGFileType ,
            properties: nil)

The problem is that the compiler say : " Use of unresolved identifier 'NSPNGFileType'". Does anyone have any idea why ?

Thanks, and sorry for my english !

Answer 1

You probably have to use .NSPNGFileType, or more explicitly NSBitmapImageFileType.NSPNGFileType

Answer 2

In Swift 3 this has changed to simply .PNG or as the full version NSBitmapImageFileType.PNG (docs).
