I would love to have that! Unfortunately, I didn’t find the time yet to think it through and write a proposal. I often use enums for modeling server calls in small apps and prototypes, something along the lines of
public enum Client {
private static let baseURLComponent = URL(string: "")!
case foo(bar: String)
case foob(bar: String, foobar: String)
private func constructURL() -> URL {
...
}
public func fetch<T: JSONInitializable>(completion: (@escaping(T?, Error?) ->
())) {
URLSession.shared.dataTask(with: constructURL()) { data, response, error in
...
if let data = data {
completion(T.init(json: JSON(data: data)), error)
} else {
completion(nil, error)
}
...
}.resume()
}
}
