Swift 4 Codable Array's
Update regarding Alamofire 5: responseJSONDecodable
.
struct Person: Codable {
let firstName, lastName: String
let age: Int
enum CodingKeys : String, CodingKey {
case firstName = "firstname"
case lastName = "lastname"
case age
}
}
Alamofire.request(request).responseJSONDecodable { (response: DataResponse<Person>) in
print(response)
}
Alamofire 4 won't add Codable support for now (see #2177), you can use this extension instead: https://github.com/Otbivnoe/CodableAlamofire.
let jsonData = """
[
{"firstname": "Tom", "lastname": "Smith", "age": 31},
{"firstname": "Bob", "lastname": "Smith", "age": 28}
]
""".data(using: .utf8)!
struct Person: Codable {
let firstName, lastName: String
let age: Int
enum CodingKeys : String, CodingKey {
case firstName = "firstname"
case lastName = "lastname"
case age
}
}
let decoded = try! JSONDecoder().decode([Person].self, from: jsonData)
Sample: http://swift.sandbox.bluemix.net/#/repl/59a4b4fad129044611590820
Using CodableAlamofire:
let decoder = JSONDecoder()
Alamofire.request(url).responseDecodableObject(keyPath: nil, decoder: decoder) { (response: DataResponse<[Person]>) in
let persons = response.result.value
print(persons)
}
keypath
corresponds to the path where the results are contained in the JSON structure. E.g:
{
"result": {
"persons": [
{"firstname": "Tom", "lastname": "Smith", "age": 31},
{"firstname": "Bob", "lastname": "Smith", "age": 28}
]
}
}
keypath
=> results.persons
[
{"firstname": "Tom", "lastname": "Smith", "age": 31},
{"firstname": "Bob", "lastname": "Smith", "age": 28}
]
keypath
=> nil
(empty keypath
throws an exception)
