Blazingly-Fast JSON Parser written in Swift

GottaGoFastJS.swift

import Foundation

public typealias JSON = AnyObject

public func JSONWithData(data: NSData) -> JSON? {
  do {
    let j = try NSJSONSerialization.JSONObjectWithData(data, options: [])
    return j
  } catch _ {
    return nil
  }
}

That's way too much complicated. You could have written it in 3 lines only.

import Foundation
public typealias JSON = AnyObject
let JSONWithData: NSData -> JSON? = { try? NSJSONSerialization.JSONObjectWithData($0, options: []) }

Still too complicated. You could've written it in two lines:

import Foundation
let JSONWithData: NSData -> AnyObject? = { try? NSJSONSerialization.JSONObjectWithData($0, options: []) }
