  如果在Playground上运行代码，需要添加以下内容：

  import PlaygroundSupport 
  
  // [...] 
  
  PlaygroundPage.current.needsIndefiniteExecution = true

  查看代码示例：

  let zomatoKey = "<Your API Key>"        
      let centerLatitude = 19.06558, centerLongitude = 72.86215 
      let urlString = "https://developers.zomato.com/api/v2.1/search?&lat=\(centerLatitude)&lon=\(centerLongitude)";
      let url = NSURL(string: urlString)
  
      if url != nil {
          let request = NSMutableURLRequest(URL: url!)
          request.HTTPMethod = "GET"
          request.addValue("application/json", forHTTPHeaderField: "Accept")
          request.addValue(zomatoKey, forHTTPHeaderField: "user_key")
  
          let task = NSURLSession.sharedSession().dataTaskWithRequest(request, completionHandler: {(data, response, error) -> Void in
              if error == nil {
                  let httpResponse = response as! NSHTTPURLResponse!
  
                  if httpResponse.statusCode == 200 {
                      do {
                          if let json = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary {
                              if let restaurants = json["restaurants"] as? [NSDictionary] {
                                  for rest in restaurants {
                                      var searchResult = [String:AnyObject?]()
                                      let restaurant = rest["restaurant"] as! NSDictionary
                                      print(restaurant["id"] as? NSString)
                                      print(restaurant["average_cost_for_two"] as? NSNumber)
                                      print(restaurant["cuisines"] as? String)
                                      print(restaurant["url"] as? String)
                                      print(restaurant["thumb"] as? String)
                                      if let location = restaurant["location"] as? NSDictionary {
                                          print(location["address"] as? String)
                                          print(location["city"] as? String)
                                          print((location["latitude"] as? NSString).doubleValue)
                                          print((location["longitude"] as? NSString).doubleValue)
                                      }
                                      print(restaurant["menu_url"] as? String)
                                      print(restaurant["name"] as? String )
                                      print(restaurant["phone_numbers"] as? String)
                                      if let user_rating = restaurant["user_rating"] as? NSDictionary {
                                          print(user_rating["aggregate_rating"] as? NSString)
                                          print(user_rating["rating_color"] as? String)
                                          print((user_rating["votes"] as? NSNumber)).doubleValue)
                                      }
                                  }
                              }
                          }
  
                      } catch {
                          print(error)
                      }
                  }
              }
          })
  
          task.resume()
      }

  这是我的实现，假设你有一个类餐厅

  func getRestaurants() {
  
      let url = NSURL(string: zomatoURLString)
  
      if url != nil {
          let request = NSMutableURLRequest(URL: url!)
          request.HTTPMethod = "GET"
          request.addValue("application/json", forHTTPHeaderField: "Accept")
          request.addValue(zomatoKey, forHTTPHeaderField: "user_key")
  
          let task = NSURLSession.sharedSession().dataTaskWithRequest(request, completionHandler: {
              (data,response,error) -> Void in
  
              if let error = error {
                  print(error)
                  return
              }
  
              //Parse Json data
  
              if let data = data {
                  self.restaurants = self.parseJsonData(data)
  
                  //reload table
                  NSOperationQueue.mainQueue().addOperationWithBlock({() -> Void in
                      self.tableView.reloadData()
                  })
  
              }
          })
  
          task.resume()
  
      }
  }
  
  
  func parseJsonData(data: NSData) -> [Restaurant] {
  
      do {
          let jsonResult = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary
  
          //Parse JSON DATA
          let jsonRestaurants = jsonResult?["restaurants"] as! [AnyObject]
  
          for res in jsonRestaurants {
              let restaurant = Restaurant()
              let myRestaurant = res["restaurant"] as! NSDictionary
              restaurant.restaurantName = myRestaurant["name"] as! String
              restaurant.restaurantType = myRestaurant["cuisines"] as! String
              restaurant.restaurantImage = myRestaurant["thumb"] as! String
              let location = myRestaurant["location"] as! [String: AnyObject]
              restaurant.restaurantLocation = location["address"] as! String
              restaurants.append(restaurant)
          }
      } catch {
          print(error)
      }
      return restaurants
  }
