What is the more elegant way to serialize my own objects with arrays in Swift

ios, json, nsjsonserialization, serialization, swift

Solution

I suggest taking this approach:

class Foo {
    var bar = Int()
}

class Bar {
    var baz = String()
    var arr = [Foo]()

    var jsonDictionary: NSDictionary {
        return [
            "baz" : self.baz,
            "arr" : self.arr.map{ $0.bar }
        ]
    }
}

let bar = Bar()
bar.baz = "some baz"
bar.arr.append(Foo())

var error: NSError?
let data = NSJSONSerialization.dataWithJSONObject(bar.jsonDictionary, options: nil, error: &error)

if error == nil && data != nil {
    // success
}

Problem

I have a classes that looks like this: ``` class Foo { var bar = Int() } class Bar { var baz = String() var arr = [Foo]() } ``` and I have an object of Bar structure that I need to serialize to JSON: ``` let instance = Bar() ``` What is the more elegant way to do it via standard library or some third-party libraries? Thanks in advance.
