Convert JSON output to an array with SwiftyJSON

Question

I have this subJSON["guestpics"] as JSON data from SwiftyJSON.

When I print(subJSON["guestpics"]) I have this:

[
  "/images\/profile_pic\/1.jpg",
  "/images\/profile_pic\/2.jpg",
  "/images\/profile_pic\/3.jpg"
]

How can I convert this to an array ?

 for (_, subJSON): (String, JSON) in json[0]["data"] {
     print(subJSON["guestpics"])
 }

So, what is the type of subJSON["guestpics"], it seems like it is an array of strings. — Sandeep

SwiftyJSON has already parsed your JSON data and prepared typed objects.

If the key subJSON["guestpics"] contains an array, then use SwiftyJSON's optional getter .array to get it:

if let guestPicsArray = subJSON["guestpics"].array {
    // here "guestPicsArray" is your array
}

Eric is correct. The JSON is already parsed when you call the JSON (data: ...) method. Therefore when you query for the guestpics key doing subJSON["guestpics"] you already have an array of strings. So you can do something like Eric suggested or let array = subJSON["guestpics"].array to store the array in a variable.

By the way, how can i loop this guestPicsArray ?

Why not directly storing the value of the key in the array? as it look like array
Does it show any error/crash when you are trying to store ?

if let arrGuest = subJSON["guestpics"] as? Array<String> {

}

Or if you are more familiar with Objective-c

if let arrGuest = arr as? NSArray {

}

you can get the array in the arrGuest object
