Set default baseURLString using manager session configuration - swift

Question

I'm developing an IOS app using swift with Alamofire library. Two files of my network model are described below, the first one is the ApiClient Class with the Alamofire manager session configuration and 2 instances of the services,in my question I'm only describing one, the Service1 struct, in this struct I'm using the Alamofire Router to request to the REST API, and I would like to know, How can I set a default baseURLString ("https://api.com/v1") using manager session configuration? instead of declare it inside each struct Service.
ApiClient.swift
class ApiClient {
var OAuthToken = "ZMpMDJhB0egjFIzFhapuWNFSBhX2conQ1e+3vlv0XrJQVcw7fRg=="
var service1: Service1
var service2: Service2
init() {
let manager = Manager.sharedInstance
manager.session.configuration.HTTPAdditionalHeaders = [
"Authorization": "Bearer \(OAuthToken)"
]
service1 = Service1()
service2 = Service2()
}
}
Service1.swift
struct Service1 {
enum Router: URLRequestConvertible {
static let baseURLString = "https://api.com/v1"
case GetList([String: AnyObject])
case GetById(String)
case Add([String: AnyObject])
case Update(String, [String: AnyObject])
case Delete(String)
case GetListFromPoint([String: AnyObject])
var method: Alamofire.Method {
switch self {
case .GetList:
return .GET
case .GetById:
return .GET
case .Add:
return .POST
case .Update:
return .PUT
case .Delete:
return .DELETE
case .GetListFromPoint:
return .GET
}
}
var path: String {
switch self {
case .GetList:
return "/endPoint"
case .GetById(let id):
return "/endPoint/\(id)"
case .Add:
return "/endPoint"
case .Update(let id, _):
return "/endPoint/\(id)"
case .Delete(let id):
return "/endPoint/\(id)"
case .GetListFromPoint:
return "/near/endPoint"
}
}
var URLRequest: NSURLRequest {
let URL = NSURL(string: Router.baseURLString)!
let mutableURLRequest = NSMutableURLRequest(URL: URL.URLByAppendingPathComponent(path))
mutableURLRequest.HTTPMethod = method.rawValue
switch self {
case .GetList(let parameters):
return Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: parameters).0
case .Add(let parameters):
return Alamofire.ParameterEncoding.JSON.encode(mutableURLRequest, parameters: parameters).0
case .Update(_, let parameters):
return Alamofire.ParameterEncoding.JSON.encode(mutableURLRequest, parameters: parameters).0
case .GetListFromPoint(let parameters):
return Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: parameters).0
default:
return mutableURLRequest
}
}
}
func getList(completionHandler: ([Object1]?, NSError?) -> ()) {
Alamofire.request(Router.GetList(["skip": 0, "limit": 100])).responseJSON { (request, response, json, error) in
//Converting json to object
}
func getById(completionHandler: ([Object1]?, NSError?) -> ()) {
Alamofire.request(Router.GetById(id)).responseJSON { (request, response, json, error) in
//Converting json to object
}
}

I think there are MANY ways you could do this. Here are a few ideas...
Store the baseURLString in the APIClient and pass the value into each of the Service initializers
Create a BaseService class where you store all common types of information between the services such as baseURLString, additional headers, etc.
Expose the baseURLString in the APIClient and pass a weak reference of the APIClient into each service.
Create a separate object such as an AppEnvironment that stores properties such as OAuth info, baseURLString, etc. that can be accessed through either a global singleton or class properties.
And there are many more ways. Hopefully one of those ideas triggers your imagination.
