I have tier to get all value from this jsonResult i want array from this like "projectArray","msg","msg2" and string like "output" ,"output_prg" i only get first array value how to get other values?
This is my result
{
"project": [{
"name": [{
"sac": "sachin",
"sag": "sagar"
}]
}, {
"output": " true",
"msg1": [{
"emp": "001",
"empname": "sachin"
}, {
"emp": "002",
"empname": "sagar"
}]
}, {
"output_prg": " true",
"msg2": [{
"id": "1",
"pr_code": "SD"
}, {
"id": "002",
"pr_code": "SJ"
}]
}]
}
This is my code
if let array = response.result.value as? NSDictionary
{
print(array)
let mainArray = array["project"] as? [[String:Any]]
print(mainArray!)
for item in mainArray!
{
print(item)
let status = item["name"]
print(status!)
}
}
Thank you in advance
Try This---->
//to get JSON return value
if let array = response.result.value as? NSDictionary
{
print(array)
let mainArray = array["project"] as? [[String:Any]]
print(mainArray?.count as Any)
if (mainArray?.count)!>0
{
let name = mainArray?[0]
let project_status = name?["name"] as? [[String:Any]]
print(name!)
}
if (mainArray?.count)!>1
{
let output = mainArray?[1]
print(output!)
}
if (mainArray?.count)!>2
{
let output_prg = mainArray?[2]
let Output_getProject = output_prg?["output_prg"]
}
}
}
Happy Coading :-)

I'm trying to access an array response within array this is how I'm getting the friends array successfully
let url = URL(string: "http://xyz/api/get-friends-in-meetings")
AF.request(url!, method: .get, parameters: nil, encoding: JSONEncoding.default, headers: headers).responseJSON{ response in
switch response.result {
case .success:
let responseValue = response.value as! NSDictionary
let friends: [NSDictionary] = responseValue["friends"] as! [NSDictionary]
//here I want to store the "meeting array so that I can use it later"
break
case .failure(let error):
print(error)
break
}
}
This is the JSON response
{
"status": 0,
"message": "Friends found.",
"friends": [
{
"id": 24,
"name": "XYZ",
"email": "Z#Y.Z",
"meetings": [
{
"meeting_with": "X",
"meeting_person_screen_name": "Y",
"meeting_purpose": "Z",
}
]
}
]
}
how do I get the "meetings" array which is within the "friends" array? I have tried the same way as I did for friends but it show an error No exact matches in call to subscript
First you need to define these structs:
struct DataResult : Decodable {
let status: Int
let message: String
let friends: [FriendsResult]
}
struct FriendsResult : Decodable {
let id: Int
let name: String
let email: String
let meetings: [MeetingsResult]
}
struct MeetingsResult: Decodable {
let meeting_with: String
let meeting_person_screen_name: String
let meeting_purpose: String
}
So after that we need the JSON Example:
// Meetings
let meeting1: [String: Any] = [
"meeting_with": "X",
"meeting_person_screen_name": "Y",
"meeting_purpose": "Z"
]
// Friends
let friend1: [String: Any] = [
"id" : 24,
"name": "XYZ",
"email": "x#y.z",
"meetings": [meeting1]
]
let friend2: [String: Any] = [
"id" : 25,
"name": "John Doe",
"email": "jd#x.doe",
"meetings": [meeting1]
]
// Main JSON
let jsonExample: [String : Any] = [
"status": 0,
"message": "Friends found.",
"friends": [friend1, friend2]
]
Well, we continue to validate the JSON and decode to "DataResult":
let valid = JSONSerialization.isValidJSONObject(jsonExample)
if valid {
do {
let dataResult = try JSONSerialization.data(withJSONObject: jsonExample, options: JSONSerialization.WritingOptions())
let dataDecode = try JSONDecoder().decode(DataResult.self, from: dataResult)
let jsonString = String(data: dataResult, encoding: .utf8)
print("JSON: \(String(describing: jsonString))")
if dataDecode.friends.count > 0 {
// Get first friend you should use guard
let friend = dataDecode.friends[0]
let meeting = friend.meetings[0]
print("\(friend.name)")
print("\(meeting.meeting_with)")
}
}
catch let error {
print("ERROR: \(error.localizedDescription)")
}
}
else {
print("Invalid JSON")
}
I have a simple array that I want to decode. I can deal with arrays in a JSON format with creating a new struct in the model class, and attributing that struct as an array in the main struct. But in this case, the json data is already on an array with 1 element. Therefore I should get the first element in the json response. I think I need to provide a decoder before I can access anything, but I don't know how that decoder model should be. The error I'm getting is:
typeMismatch(Swift.Array<Any>, Swift.DecodingError.Context(codingPath: [], debugDescription: "Expected to decode Array<Any> but found a dictionary instead.", underlyingError: nil))
JSON data I want to decode: (notice the data is on a array)

Most of the fields are missing from your model. Here is how it should look like instead:
struct Country: Codable {
let name: String
let topLevelDomains: [String]
let alpha2Code: String
let alpha3Code: String
let callingCodes: [String]
let capital: String
let altSpellings: [String]

let nativeName: String
let numericCode: String
let currencies: [String]
let languages: [String]
let translation: Translation
let relevance: String
}
struct Translation: Codable {
let de: String
let es: String
let fr: String
let ja: String
let it: String
}
I found out that there was a problem in my http request. I used Alamofire in the request part and I don't experience the problem anymore. The issue seemed to be related to the decoding but I don't know. I'm posting the final code if anyone experiences the same issue.
import Foundation
import Alamofire
struct CountryManager {
let countryURL = "https://restcountries-v1.p.rapidapi.com/name/"
func fetchData(_ countryName: String) {
let urlString = "\(countryURL)\(countryName)"
print(urlString)
performRequest(urlString)

func performRequest(_ urlString: String){
let headers: HTTPHeaders = [
"x-rapidapi-host": "restcountries-v1.p.rapidapi.com",
"x-rapidapi-key": "apices"

AF.request(urlString, headers: headers).responseJSON { response in
self.parseJSON(response.data!)

Got the following JSON! I’m trying to get a single url from those tree inside images array! Can anyone please explain me how I can get it.
let dataTask = session.dataTask(with: request) { (data, response, error) in
do {
let json = try? JSONSerialization.jsonObject(
with: data!,
options: JSONSerialization.ReadingOptions.mutableContainers
) as! [String: AnyObject]
if let artists = json?["artists"] as? [String: AnyObject] {
if let items = artists["items"] {
for i in 0..<items.count {
let item = items[i] as? [String: AnyObject]
let name = item?["name"] as! String
self.nameArray.append(name)
let popularity = item?["popularity"] as! Int
self.popuArray.append(popularity)
if let artists = item["artists"] as? String: AnyObject {
if let images = artists["images"] as? [String: AnyObject] {
let imageData = images[0]
}
}
print(name)
print(popularity)
}
}
}
}
}
I am able to get the values from name and popularity.
No way for this url… inside images!
My json is a spotify.. api

I want to pick any url i want from those 3.
It appears you just need to update this line..
if let images = artists["images"] as? [String: AnyObject] {
to
if let images = artists["images"] as? [[String: AnyObject]] {
if let firstImage = images.first, let urlString = firstImage["url"] as? String {
let url = URL(string: urlString)
}
}
[String:AnyObject] casts to a Dictionary object, [[String:AnyObject]] casts to an Array of Dictionary objects which is what you need in this case
I want to save the subcategory data in this form [[value1,value2,...],[value1, value2],[value1],.....] in the following code
var subcategories = [SubCategory]()
for (_, item) in json {
//do something with item.id, item.name
for (_, subcategory) in item["subcategory"] {
let subcategory = SubCategory(
id: Int(subcategory ["id"].stringValue),
name: subcategory ["name"].string,
desc: subcategory ["desc"].string,
image: subcategory ["image"].string,
coupon: Int(subcategory ["coupon"].stringValue),
icon: subcategory ["icon"].string,
order: Int(subcategory ["order"].stringValue),
aname: subcategory ["aname"].string,
options: Int(subcategory ["options"].stringValue),
items: subcategory ["items"].arrayObject
)
subcategories.append(subcategory)
}
print(subcategories.count)
for sub in subcategories {
print(sub.name)
print(sub.id)
print(sub.desc)
self.SUBCATNAME.append(sub.name!)
self.SUBARRAY?.append(self.SUBCATNAME)
}
print(self.SUBCATNAME)
print(self.SUBARRAY)
}
I need to append all the subcategory name in an array of dictionary like the above structure. Here i created SUBARRAY as var SUBARRAY:[[String]] = []. but the value is coming as nil. Here i am getting the json data from Api using Swiftyjson. How to implement this??
my sample json data is as below:
like wise so many subcategories are there
[
{
"id": "244",
"name": "PIZZAS",
"subcategory": [
{
"id": "515",
"name": "MARGARITA",
"description": "Cheese and Tomato",
"image": "",
"icon": "",
"coupon": "1",
"order": "1",
"aname": "",
"options": "2"
},
{
"id": "516",
"name": "ABC",
"description": "HNDDSGHFD",
"image": "",
"icon": "",
"coupon": "1",
"order": "1",
"aname": "",
"options": "2",
},
{
"id": "516",
"name": "DEF",
"description": "HFDGFJJFHFKH",
"image": "",
"icon": "",
"coupon": "1",
"order": "1",
"aname": "",
"options": "2",
}
]
},
{
......
}
]
if you try this code
for (NSDictionary *dictionary in ArrCategory)
{
NSMutableArray *sub_cat_data=[dictionary objectForKey:#"sub_cat_data"];
for (NSDictionary *sub_cat_dict in sub_cat_data)
{
NSMutableArray *sub_cat_data=[sub_cat_dict objectForKey:#"sub_data"];
for (NSDictionary *dictionary1 in sub_cat_data)
{
NSMutableDictionary *Dic_Sub_cat=[[NSMutableDictionary alloc]init];
NSString *str_dic_id=[dictionary1 objectForKey:#"sub_id"];
NSString *str_dic_name=[dictionary1 objectForKey:#"sub_name"];
[Dic_Sub_cat setObject:str_dic_id forKey:#"sub_id"];
[Dic_Sub_cat setObject:str_dic_name forKey:#"sub_name"];
[Dic_Sub_cat setObject:#"0" forKey:#"sub_Chekid"];
[New_ArrCategory addObject:Dic_Sub_cat];
}
}
}
swift example
if let results: NSMutableArray = jsonResult["data"] as? NSMutableArray
{
var ArrMoodtype2 : NSMutableArray!
ArrMoodtype2 = NSMutableArray()
ArrMoodtype2 = results
ArrFeel = NSMutableArray()
for var i = 0; i < ArrMoodtype2.count; i++
{
var Dic : NSMutableDictionary!
Dic = NSMutableDictionary()
let tempDic: NSMutableDictionary = ArrMoodtype2[i] as! NSMutableDictionary
let strMoodCatID = tempDic ["mood_cat_id"] as! String
let strMoodID = tempDic ["mood_id"] as! String
let strMoodImage = tempDic ["mood_image"] as! String
let strMoodName = tempDic ["mood_name"] as! String
Dic.setObject(strMoodCatID, forKey: "mood_cat_id")
Dic.setObject(strMoodID, forKey: "mood_id")
Dic.setObject(strMoodImage, forKey: "mood_image")
Dic.setObject(strMoodName, forKey: "mood_name")
ArrFeel.addObject(Dic)
}
}
I am trying to fetch the Json data from Api which is in the following format
[
{
"id": "244",

"coupon": "1",
"icon": "",
"order": "1",
"aname": "",
"options": "2",
"subcategory": [
{
"id": "515",

"item": [
{
"id": "1749",
"name": "9 Inch Thin & Crispy Margarita",
"description": "",
"price": "3.40",
"coupon": "1",
"image": "",
"options": "2",
"order": "1",
"addon": "495",

},
{
"id": "1750",
"name": "12 Inch Thin & Crispy Margarita",

"coupon": "1",
"image": "",
"options": "2",
"order": "2",
"addon": "496",
"aname": "",
"icon": ""
}
]
}
How can i fetch the "subcategory name" as well as " items name". Please help me out.I have written some codes and tried to fetch but not working.
var json: NSArray!
do {
json = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions()) as? NSArray
} catch {
print(error)
}
self.AllData = json.valueForKey("subcategory") as! Array<String>
print(self.AllData)
print(self.AllData.count)
But its not fetching any value
Other way also I have tried but still no data fetching . only the data is coming in json1.
do {
let json1 = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions())
// print(json1)
if let subcategory = json1["subcategory"] as? [[String: AnyObject]] {
for subname in subcategory {
if let name = subname["name"] as? String {
print(name)
}
if let items = subname["item"] as? [[String: AnyObject]] {
for item in items {
if let itemName = item["name"] as? String {
print(itemName)
}
}
}
}
}
} catch {
print(error)
}
At first its an array of objects/Dictionary.And you are creating an array of string. Thats why for subcategory it will not work.You need to create an array of Dictionaries like this:
do {
let json1 = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions())
self.AllData = json1.valueForKey("name") as! Array<String>
print(self.AllData)
print("Number of menu = \(json1.count)")
for var i in 0..<json1.count {
print(" \n \(i+1) row menu \n")
if let subs = json1[i]["subcategory"] as? [[String: AnyObject]] {
//print(subs)
for sub in subs {
if let name = sub["name"] as? String {
print("subcategory name= \t \(name)")
//print(name)
}
if let desc = sub["description"] as? String {
print("description= \t \(desc)")
// print(desc)
}
}
print("Number of subcategory= \(subs.count)")
for var i in 0..<subs.count {
if let items = subs[i]["item"] as? [[String: AnyObject]] {
print("items = ")
print(items.count)
for item in items {
if let itemName = item["name"] as? String {
print(itemName)
}
}
}
}
}
}
}catch {
print(error)
}
Try this one it will work accoording to your json data
This may just be a problem when cutting and pasting into the question, but it looks like your JSON data isn't formatted correctly (the []s and {}s don't match up). As the previous commentor said, you're dealing with an array of dictionaries not an array of strings. Try something like this:
do {
let json = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions())
if let subs = json[0]["subcategory"] as? [[String: AnyObject]] {
for sub in subs {
if let name = sub["name"] as? String {
print(name)
}
if let items = sub["item"] as? [[String: AnyObject]] {
for item in items {
if let itemName = item["name"] as? String {
print(itemName)
}
}
}
}
}
} catch {
print(error)
}
