In this episode we talk about modeling API Endpoints as first class types, rather than relying on strings and string interpolation scattered across your application. For this we'll leverage Swift enums with associated values.

let baseURL = NSURL(string: "http://httpbin.org")!

enum Endpoint {
    case UserAgent
    case Links(Int)

    func url() -> NSURL {
        switch self {
        case .UserAgent:
            return baseURL.URLByAppendingPathComponent("/user-agent")
        case .Links(let n):
            return baseURL.URLByAppendingPathComponent("/links/\(n)")
        }
    }
}

request(Endpoint.UserAgent.url())
request(Endpoint.Links(5).url())
