JSON to NSData

[magnusstubman]

Given that I have a JSON object, how do I get a NSData representation, which is suitable for sending over the network, with e.g. a POST request?

[k06a]

This can be achieved with this code:

var err: NSError?
let data = NSJSONSerialization.dataWithJSONObject(json.object!, options: nil, error: &err)

@k06a, Is there any argument for not adding a wrapper for that operation to SwiftyJSON?

[k06a]

What wrapper do you mean?

[magnusstubman]

e.g. let data: NSData = someJson.toData()or similare

Use

let object = json.object
if let data = NSJSONSerialization.dataWithJSONObject(object, options: NSJSONReadingOptions..AllowFragments, error: nil) {
   //post your data to server
} else {
   //error
}
