How do I parse JSON in iOS using Swift?

You can use the JSONDecoder class in Swift to parse JSON data. First, ensure your JSON data is in the correct format.

Can you show me a simple example?

Sure! Here's a basic example:

struct User: Codable {
    let id: Int
    let name: String
}

let jsonData = "{\"id\": 1, \"name\": \"John Doe\"}".data(using: .utf8)!

let user = try? JSONDecoder().decode(User.self, from: jsonData)
print(user?.name) // Output: John Doe

What if my JSON structure is more complex?

For complex JSON structures, you can create nested structs that conform to the Codable protocol. Just match the JSON keys with your struct properties.

Are there any libraries that can help with JSON parsing?

Yes, libraries like Alamofire and SwiftyJSON can simplify networking and JSON parsing in iOS.
