Installation

CocoaPods

CocoaPods is a dependency manager for projects. For its documentation on Usage and Installation, visit this site.

On your Podfile add:

pod 'HTTPLayer'

On your Terminal, navigate to your project folder and run this command:

$ pod install

Usage

Configuration

To use HTTPLayer you just need to add its import on any class you might want.

import HTTPLayer

It is recommended to configure all your hosts, contexts, headers and security options on the AppDelegate file, like the example bellow:

• For hosts, contexts, and headers configuration, inside the " func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {} " add configuration like:

//For adding Hosts and Context or Headers
HTTP.Config.add

//For setting multiplus Hosts and Context or Headers at once
HTTP.Config.set

//For retrieving Hosts and Context or Headers that has already been added
HTTP.Config.get

//For changing already added Headers
HTTP.Config.change

//For removing any Header that has already been added
HTTP.Config.remove

• For security options, also inside the " func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {} " add configuration like:

//For enabling SSL Pinning, Debug Mode, Continue Without Pinning and setting SHA256 encoded with Base64 Hash Keys and/or Certificate files .cer and .crt to expecific Hosts
HTTP.Security.set

//For retrieving the any configuration made with the HTTP.Security.set 
HTTP.Security.get

These are the already implemented methods that you can choose from. All of them are accessable through "HTTP.Request" and all of them are documented and avaliable on the Xcode Autocomplete Shortcut. (E and D stands for Generic Object that conforms to Encodable for E and Decodable for D)

• GET - (Add the parameter "receivingAsError: T.self" to use a custom Error Response Object)

//Without Parameters:
HTTP.Request.get(from: String, withHostAndContext: String, andHeaders: String, receivingObjectType: D.self, completion: (Result<ResponseObject<D>, ErrorObject<ER>>) -> ()) 

//Path Parameters:
HTTP.Request.get(from: String, usingPathParameters: [String]?, fromHostAndContext: String, andHeaders: String?, receivingObjectType: D.self, completion: (Result<ResponseObject<D>, ErrorObject<ER>>) -> ())

//Query Parameters:
HTTP.Request.get(from: String, usingQueryParameters: [String : String]?, fromHostAndContext: String, andHeaders: String?, receivingObjectType: D.self, completion: (Result<ResponseObject<D>, ErrorObject<ER>>) -> ())

• POST - (Add the parameter "receivingAsError: T.self" to use a custom Error Response Object)

HTTP.Request.post(to: String, withBody: Encodable, fromHostAndContext: String, andHeaders: String?, receivingObjectType: D.self, completion: (Result<ResponseObject<D>, ErrorObject<ER>>) -> ())

• PUT - (Add the parameter "receivingAsError: T.self" to use a custom Error Response Object)

//Path Parameters:
HTTP.Request.put(on: String, withBody: E, andPathParameters: [String]?, fromHostAndContext: String, andHeaders: String?, receivingObjectType: D.self, completion: (Result<ResponseObject<D>, ErrorObject<ER>>) -> ())

//Query Parameters:
HTTP.Request.put(on: String, withBody: E, andQueryParameters: [String : String]?, fromHostAndContext: String, andHeaders: String?, receivingObjectType: D.self, completion: (Result<ResponseObject<D>, ErrorObject<ER>>) -> ())

• DELETE - (Add the parameter "receivingAsError: T.self" to use a custom Error Response Object)

//Path Parameters
HTTP.Request.delete(from: String, withPathParameters: [String]?, fromHostAndContext: String, andHeaders: String?, receivingObjectType: D.self, completion: (Result<ResponseObject<D>, ErrorObject<ER>>) -> ())

//Query Parameters
HTTP.Request.delete(from: String, withQueryParameters: [String : String]?, fromHostAndContext: String, andHeaders: String?, receivingObjectType: D.self, completion: (Result<ResponseObject<D>, ErrorObject<ER>>) -> ())

All the Requests Methods return a Result<ResponseObject, ErrorObject> The recomended way to use the return Result<> is like :

switch response {
case .success(let success):
    //To retrieve the parsed Response
    success.response
    
    //To retrieve the response Headers
    success.headers
case .failure(let failure):
    //To retrieve the custom Error Response
    failure.response
    
    //To retrieve the error Object
    failure.error
}
