Use nil instead of Optional(<null>) for null value in JSON

Question

In Swift, NSJSONSerialization.JSONObjectWithData uses Optional(<null>) for null value in JSON. Is that possible to tell the parse to use nil instead (i.e., drop fields with null values because Swift Dictionary doesn't allow nil value)?

Answer 1

NSJSONSerialization uses NSNull objects, and that's what you're seeing; you can simply check for them by comparing to NSNull().

Answer 2

Optional() is an NSNull value. You can avoid error like this:

if !(myField is NSNull) {
    //Whatever you want to do with myField when not null
} else {
    //Whatever you want to do when myField is null
}
