Alamofire variables or parameters support in url path - swift

Question

Does Alamofire support variables in a url path, I have looked for an example but i can't find it.
I have looked in their their docs and unit tests.
It is pretty common for apis to be written with url support for the following:
http://someapi.com/users/{user}/profile
I have looked through their examples in URLEncoding, but i cant find nothing that does the above, examples only seem to add query parameters.

Alamofire relies on the Foundation URL struct, so you need to look there.
URLs offer several different mechanisms for constructing them, the one you could be using is path component, for example:
var url = URL(string: "http://someapi.com/users")
let user = "user"
url?.appendPathComponent(user)
url?.appendPathComponent("profile")
Additionally, you could leverage enums to clean up a bit and maybe construct URLs from strings, something like this:
enum MyURLScheme {
case profile(user: String)
var url: URL? {
switch self {
case .profile(let user):
let url = URL(string: "http://someapi.com/users/\(user)/profile")
return url
}
}
}
let profileURL = MyURLScheme.profile(user: "user").url
EDIT: You can also use Alamofire Router class for building requests, taken from here:
enum Router: URLRequestConvertible {
case search(query: String, page: Int)
static let baseURLString = "https://example.com"
static let perPage = 50
// MARK: URLRequestConvertible
func asURLRequest() throws -> URLRequest {
let result: (path: String, parameters: Parameters) = {
switch self {
case let .search(query, page) where page > 0:
return ("/search", ["q": query, "offset": Router.perPage * page])
case let .search(query, _):
return ("/search", ["q": query])
}
}()
let url = try Router.baseURLString.asURL()
let urlRequest = URLRequest(url: url.appendingPathComponent(result.path))
return try URLEncoding.default.encode(urlRequest, with: result.parameters)
}
}
Alamofire.request(Router.search(query: "foo bar", page: 1))
