Browse podcasts with MangerKit. The MangerKit Swift package provides a JSON HTTP client that lets you request combined ranges of podcast feeds from the manger-http service, a caching RSS feed proxy.
MangerKit is used in the Podest podcast app.
Requesting all episodes of three podcasts. You can limit the time range with the since property.
import Foundation
import Patron
import MangerKit
let url = URL(string: "https://your.endpoint")!
let s = URLSession(configuration: .default)
let p = Patron(URL: url, session: s)
let svc = Manger(client: p)
struct Query: MangerQuery {
let url: String
let since: Date
init(url: String, since: Date = Date(timeIntervalSince1970: 0)) {
self.url = url
self.since = since
}
}
let queries: [MangerQuery] = [
Query(url: "http://feeds.wnyc.org/newyorkerradiohour"),
Query(url: "http://feed.thisamericanlife.org/talpodcast"),
Query(url: "http://feeds.serialpodcast.org/serialpodcast")
]
try! svc.entries(queries) { result, error in
print(error ?? result)
}The result is an unprocessed array of dictionaries, [[String: AnyObject]]?, typed Any? because JSON. Please refer to manger-http for details.

The simple error type also covers invalid queries.
enum MangerError: Error {
case unexpectedResult(result: Any?)
case cancelledByUser
case noQueries
case invalidQuery
case niy
}Today, I don’t see why queries shouldn’t be struct—why we should be critical of using protocols.
protocol MangerQuery {
var url: String { get }
var since: Date { get }
}protocol MangerService {
var client: JSONService { get }
@discardableResult func feeds(
_ queries: [MangerQuery],
cachePolicy: NSURLRequest.CachePolicy,
cb: @escaping (_ error: Error?, _ payload: [[String : AnyObject]]?) -> Void
) throws -> URLSessionTask
@discardableResult func feeds(
_ queries: [MangerQuery],
cb: @escaping (_ error: Error?, _ payload: [[String : AnyObject]]?) -> Void
) throws -> URLSessionTask
@discardableResult func entries(
_ queries: [MangerQuery],
cachePolicy: NSURLRequest.CachePolicy,
cb: @escaping (_ error: Error?, _ payload: [[String : AnyObject]]?) -> Void
) throws -> URLSessionTask
@discardableResult func entries(
_ queries: [MangerQuery],
cb: @escaping (_ error: Error?, _ payload: [[String : AnyObject]]?) -> Void
) throws -> URLSessionTask
@discardableResult func version(
_ cb: @escaping (_ error: Error?, _ service: String?) -> Void
) throws -> URLSessionTask
}var client: JSONService { get }The client property gives access to the underlying Patron client, providing hostname and status of the remote service.
