How can I serialize a struct to send to an api

To serialize a struct in Swift to send to an API, you can use the Codable protocol, which is a type alias for the Encodable and Decodable protocols. This allows you to easily convert your struct to and from JSON. Here’s a basic example:

1. Define your struct and conform it to Codable:

   struct Drink: Codable {
       let name: String
       let size: String
       let price: Double
   }
   

2. Serialize the struct to JSON:

   let drink = Drink(name: "Latte", size: "Medium", price: 3.50)
   let encoder = JSONEncoder()
   
   do {
       let jsonData = try encoder.encode(drink)
       // Convert jsonData to a JSON string for sending to an API
       if let jsonString = String(data: jsonData, encoding: .utf8) {
           print(jsonString)
       }
   } catch {
       print("Failed to encode drink: \(error)")
   }
   

3. Send the JSON data to an API:

   let url = URL(string: "https://api.example.com/drinks")!
   var request = URLRequest(url: url)
   request.httpMethod = "POST"
   request.setValue("application/json", forHTTPHeaderField: "Content-Type")
   request.httpBody = jsonData
   
   let task = URLSession.shared.dataTask(with: request) { data, response, error in
       if let error = error {
           print("Error sending data: \(error)")
           return
       }
       // Handle response here
   }
   task.resume()
