SwiftyJSON - Returning json array from func - json

Question

I am working on my local json api and it works quite fine with receiving and parsing data using swiftyjson and alamofire, but when it comes to return these data, I have some troubles:
import Alamofire
import SwiftyJSON
...
func getApi() -> Array<JSON> {
let user = "user"
let password = "password"
Alamofire.request(.GET, "http://localhost/api/")
.authenticate(user: user, password: password)
.responseString { (req, res, body, error) in
if let data = (body)!.dataUsingEncoding(NSUTF8StringEncoding) {
let json = JSON(data: data)
println(json) // works fine
return json // does not work
}
}
}
So it prints "JSON is not convertible to Void"...
Anybody knows how to deal with this?
You think i am doing right using alamofire for a "http-basic-authentification" ?
Greetings and thanks!

Answer 1

If your api returns a JSON object, alamofire provides a .responseJSON, and swiftyJSON can wrap that response.
Also don't forget that this request is asynchronous, so you probably need to get these results in a completion handler, something like this:
func getApi(completionHandler: (jsonResponse: JSON) -> () {
let user = "user"
let password = "password"
Alamofire.request(.GET, "http://localhost/api/")
.authenticate(user: user, password: password)
.responseJSON { (req, res, JSON, error) in
println(json) // works fine
completionHandler(json)
}
}
}
Call the method like so:
getAPI(completionHandler: { (response: JSON) -> () in
// do something with your response. If the JSON contains an array you can iterate through it here.
}
Next good thing will be to check the "Response Serialization" section on Alamofire doc.

Answer 2

You are attempting to return an object of type JSON inside a block that has no return type (Void).

Answer 3

according to your variable names, you should set
res = json
or
res.setResponse(json)
or smt like that. Can't check now because I'm far away from my mac at the moment

Answer 4

Your function returns an array of JSON: [JSON].
You are trying to return a single JSON type object.
Change your return statement to return an array:
return [json] // should work
EDIT: I misread the code when I posted my answer. You are calling an async method, Alamofire.request. That method returns immediately, but the data isn't actually loaded until sometime later. Your current design won't work.
#Gwendle's answer is the right one. You need to refactor your method to take a completion block and put the response handling in that completion block.
