Updating a json

[yelled3]

Hi, is there a way to update a JSON object? e.g

let json = JSON(data: dataFromNetworking)
json[0]["user"]["name"] = "new user name"

You need to fully rewrap your edited object in JSON enum or propose another genius solution for editing SwiftyJSON :)

Try this fork: k06a/SwiftyJSON/tree/editing I think this functionality will be implemented in SwiftyJSON soon, method names and form of calls may be changed.

Following NSJSONSerialization.JSONObjectWithData there are mutable data in JSON, but the first thing is set the data safety. If I do not know the type of the data, I can't set the data to unknown type. If I do know the type, I can set the data like this:

var newJson: JSON?
if let dictionary = json[999]["user"].dictionary {
    //It's safe
    var newObject = json.array
    (newObject[999] as Dictionary<String, AnyObject>)!["user"] = "new user name"
    newJson = JSON(object: newObject)
} else {
    //do something where dictionary is not the Dictionary<String, Anyobject>
}

Hi @k06a, thanks for the reply :-)

I assume you're referencing:
https://github.com/k06a/SwiftyJSON/blob/editing/Source/SwiftyJSON.swift#L229-L263

I could find any other usage (tests or documentation)...

@yelled3 you can see example of usage in my PR: #61

@yelled3 just added new syntax:

let json2 = json.updated((0,"user","name"), newValue: JSON(object: "Anton Bukov"))

It is mush shorter and readable :)

@k06a @yelled3
I will release the 2.0.0 version of SwiftJSON in a few days, like this:

var json = JSON(object: object)
value[0]["id"] = "12345667"
println(value[0]["id"]) // print "1234567"
value[0]["id"] = "789012"
println(value[0]["id"]) // print "789012"

var json1:JSON = 12345677
var json2:JSON = "hello"
var json3:JSON = [1,2,3]
var json4:JSON = ["name":"tangplin",list:[1,2,3,4]]
//Update
json1= 456
json2= "www"
json3[0] = 4
json4["name"] = "Jack"

It's very cool!

Looks most native way to update a nested JSON. Are you using mutable collections inside JSON enum?

Done in 59996b2 748ef28 eb7cc54 at develop branch.
It's need more test before merge into the master branch.
