I’m in chapter 6 of the 5th version of the book and getting the following error:

“Argument passed to call that takes no arguments”

on the following line of  
let newAttachment = ImageAttachment(entity: description!, insertInto: manager.destinationContext)

Did I forget something in another file?

Just after I pressed send, I discovered my error. In the ImageAttachment class, I failed to put a colon here: “class ImageAttachment: Attachment”

class ImageAttachment: Attachment {  
@NSManaged var image: UIImage?  
@NSManaged var width: Float  
@NSManaged var height: Float  
@NSManaged var caption: String

}
