<h1><a href="https://github.com/mrap/SwiftJSONParser" rel="nofollow">SwiftJSONParse</a>: Parse JSON like a badass</h1>

Dead-simple and easy to read!

<h3>Example: get the value <code>"mrap"</code> from <code>nicknames</code> as a String from this JSON response</h3>

<pre><code>{
 "other": {
 "nicknames": ["mrap", "Mikee"]
}
</code></pre>

It takes your json data <code>NSData</code> as it is, no need to preprocess.

<pre><code>let parser = JSONParser(jsonData)

if let handle = parser.getString("other.nicknames[0]") {
 // that's it!
}
</code></pre>

Disclaimer: I made this and I hope it helps everyone. Feel free to improve on it!

Parsing JSON in Swift is an excellent job for code generation. I've created a tool at <a href="http://www.guideluxe.com/JsonToSwift" rel="nofollow">http://www.guideluxe.com/JsonToSwift</a> to do just that.

You supply a sample JSON object with a class name and the tool will generate a corresponding Swift class, as well as any needed subsidiary Swift classes, to represent the structure implied by the sample JSON. Also included are class methods used to populate Swift objects, including one that utilizes the NSJSONSerialization.JSONObjectWithData method. The necessary mappings from the NSArray and NSDictionary objects are provided.

From the generated code, you only need to supply an NSData object containing JSON that matches the sample provided to the tool.

Other than Foundation, there are no dependencies.

My work was inspired by <a href="http://json2csharp.com/" rel="nofollow">http://json2csharp.com/</a>, which is very handy for .NET projects.

Here's how to create an NSData object from a JSON file.

<pre><code>let fileUrl: NSURL = NSBundle.mainBundle().URLForResource("JsonFile", withExtension: "json")!
let jsonData: NSData = NSData(contentsOfURL: fileUrl)!
</code></pre>

Swift 4 

Create a Project 

Design StoryBoard With a Button and a UITableview

Create TableViewCell VC

In Button Action Insert the folloeing Codes

Remember This Code for Fetch Array of Data in an Api

<pre><code>import UIKit

class ViewController3: UIViewController,UITableViewDelegate,UITableViewDataSource {

 @IBOutlet var tableView: UITableView!
 var displayDatasssss = [displyDataClass]()
 override func viewDidLoad() {
 super.viewDidLoad()

 // Do any additional setup after loading the view.
 }
 func numberOfSections(in tableView: UITableView) -&gt; Int {
 return 1
 }
 func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
 return displayDatasssss.count
 }
 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -&gt; UITableViewCell {
 let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell1") as! TableViewCell1
 cell.label1.text = displayDatasssss[indexPath.row].email
 return cell
 }
 override func didReceiveMemoryWarning() {
 super.didReceiveMemoryWarning()
 // Dispose of any resources that can be recreated.
 }

 @IBAction func gettt(_ sender: Any) {

 let url = "http://jsonplaceholder.typicode.com/users"
 var request = URLRequest(url: URL(string: url)!)
 request.httpMethod = "GET"
 let configuration = URLSessionConfiguration.default
 let session = URLSession(configuration: configuration, delegate: nil, delegateQueue: OperationQueue.main)
 let task = session.dataTask(with: request){(data, response,error)in
 if (error != nil){
 print("Error")
 }
 else{
 do{
 // Array of Data 
 let fetchData = try JSONSerialization.jsonObject(with: data!, options: .mutableLeaves) as! NSArray

 for eachData in fetchData {

 let eachdataitem = eachData as! [String : Any]
 let name = eachdataitem["name"]as! String
 let username = eachdataitem["username"]as! String

 let email = eachdataitem["email"]as! String
 self.displayDatasssss.append(displyDataClass(name: name, username: username,email : email))
 }
 self.tableView.reloadData()
 }
 catch{
 print("Error 2")
 }

 }
 }
 task.resume()

 }
}
class displyDataClass {
 var name : String
 var username : String
 var email : String

 init(name : String,username : String,email :String) {
 self.name = name
 self.username = username
 self.email = email
 }
}
</code></pre>

This is for Dictionary data Fetching

<pre><code>import UIKit

class ViewController3: UIViewController,UITableViewDelegate,UITableViewDataSource {

 @IBOutlet var tableView: UITableView!
 var displayDatasssss = [displyDataClass]()
 override func viewDidLoad() {
 super.viewDidLoad()

 // Do any additional setup after loading the view.
 }
 func numberOfSections(in tableView: UITableView) -&gt; Int {
 return 1
 }
 func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
 return displayDatasssss.count
 }
 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -&gt; UITableViewCell {
 let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell1") as! TableViewCell1
 cell.label1.text = displayDatasssss[indexPath.row].email
 return cell
 }
 override func didReceiveMemoryWarning() {
 super.didReceiveMemoryWarning()
 // Dispose of any resources that can be recreated.
 }

 @IBAction func gettt(_ sender: Any) {

 let url = "http://jsonplaceholder.typicode.com/users/1"
 var request = URLRequest(url: URL(string: url)!)
 request.httpMethod = "GET"
 let configuration = URLSessionConfiguration.default
 let session = URLSession(configuration: configuration, delegate: nil, delegateQueue: OperationQueue.main)
 let task = session.dataTask(with: request){(data, response,error)in
 if (error != nil){
 print("Error")
 }
 else{
 do{
 //Dictionary data Fetching
 let fetchData = try JSONSerialization.jsonObject(with: data!, options: .mutableLeaves) as! [String: AnyObject]
 let name = fetchData["name"]as! String
 let username = fetchData["username"]as! String

 let email = fetchData["email"]as! String
 self.displayDatasssss.append(displyDataClass(name: name, username: username,email : email))

 self.tableView.reloadData()
 }
 catch{
 print("Error 2")
 }

 }
 }
 task.resume()

 }
}
class displyDataClass {
 var name : String
 var username : String
 var email : String

 init(name : String,username : String,email :String) {
 self.name = name
 self.username = username
 self.email = email
 }
}
