Extracting JSON Data - - arrays

Question

I have the following JSON data structure being pulled from FBSDKGraphRequest.
data = (
{
id = "<USER_ID_GOES_HERE>";
name = "Tom Jones";
picture = {
data = {
"is_silhouette" = 0;
url = "<USER_IMAGE_URL_GOES_HERE>";
};
};
},
{
id = "<USER_ID_GOES_HERE>";
name = "Tom Jones";
picture = {
data = {
"is_silhouette" = 0;
url = "<USER_IMAGE_URL_GOES_HERE>";
};
};
},
{
id = "<USER_ID_GOES_HERE>";
name = "Tom Jones";
picture = {
data = {
"is_silhouette" = 0;
url = "<USER_IMAGE_URL_GOES_HERE>";
};
};
},
I want to extract the data and place it into an array. I am having difficulty with the first "data" key.
Heres my FBSDKGR:
let params = ["fields": "name, picture.type(large)"]
let request = FBSDKGraphRequest(graphPath: "me/taggable_friends", parameters: params)
request!.start { (connection, result, error) -> Void in
if error != nil {
print("There is some error getting friends", error!)
}
else if result != nil {
print("Here is the result", result!)

With an extra dependency, if you don't mind.
import SwiftyJSON
let json = JSON(result) // after you get result from FBSDKGR
let data = json["data"].array
for (index, _) in data.enumerated() {
if let id = json["data", index, "id"].int {
// add to your array
if let name = json["data", index, "name"].string {
// continue nesting...
}
}
}

As your JSOND dta is array of dictionary so , we can cast the result by the following way . First of all we will take two array , one is for names list and other is for picture details . here picture details array is array of dictionary . let's go for code
var namesArray = [String]()
var ImageDetailsArrayDict= [[String :AnyObject]]()
let params = ["fields": "name, picture.type(large)"]
let request = FBSDKGraphRequest(graphPath: "me/taggable_friends", parameters: params)
request!.start { (connection, result, error) -> Void in
if error != nil {
print("There is some error getting friends", error!)
}
else if result != nil {
print("Here is the result", result!)
if let response = result["data"] as? [[String :AnyObject]] {
for i in 0..<response.count {
namesArray.append(response[i]["name"] as! String)
ImageDetailsArrayDict.append(response[i]["picture"])
}
}
}
}
Now , we have two array . so we can easily populate it in the tableView .
Good luck .
