Carthage for all
Carthage
• Decentralized
• No .xcworkspace
• Clean & Simple
• Very Easy to distribute
• Increasing
• Centralized
• .xcworkspace
• Easy to use
• Easy to distribute
• Already many
Cocoapodshttps://github.com/Carthage/Carthage https://cocoapods.org/
Carthage
$ brew update$ brew install carthage$ cd move/to/app/root$ vi Cartfile
github "Alamofire/Alamofire" == 3.1.2
wq$ carthage update -platform ios
Carthage
Carthage
• Pros:
• Project remains clean.
• No build time.
• Cons:
• Library build time.
• Relatively fewer libraries.
If library doesn’t compatible with
Carthage?
Fork!
Tweak!
(Pull Request!)
Just 4 steps
1. Create CocoaTouch Framework
2. Add files to Framework target
3. Make scheme shared
4. git push and tag in Github
I made 5 libraries or more
Carthage Compatible for Qolk.
Many Thanks.

Alamofire & BrightFutures
// AlamofireClient.swift
struct AlamofireClient { static let sharedInstance = AlamofireClient() let alamofire: Manager init() { let configuration = NSURLSessionConfiguration.defaultSessionConfiguration() configuration.timeoutIntervalForResource = RequestTimeoutSec alamofire = Manager(configuration: configuration) } static func requestJSON(URLRequest: URLRequestConvertible) -> Future<JSONResponse, ErrorResponse> { let promise = Promise<JSONResponse, ErrorResponse>() sharedInstance.alamofire.request(URLRequest) .validate() .responseJSON(options: .AllowFragments) { (response) -> Void in log.debug("REQUEST: \(response.request)") log.debug("RESPONSE: \(response.response)”)
switch response.result { case .Success(let json): log.debug("[QIITA] JSON: \(json)") promise.success(JSONResponse(json: json, response: response.response!)) case .Failure(let error): log.debug("[QIITA] ERROR: \(error.localizedDescription)") self.errorHandling(error, response: response.response) promise.failure(ErrorResponse(nsError: error, response: response.response)) } } return promise.future } … } Return future.
Responses
// AlamofireClient.swift
struct JSONResponse { var json = JSON([]) var response: NSHTTPURLResponse? var rateLimit: Int? var rateRemaining: Int? init(json: AnyObject?, response: NSHTTPURLResponse?) { if let json = json { self.json = JSON(json) } if let response = response { self.response = response let headers = JSON(response.allHeaderFields) self.rateLimit = headers["Rate-Limit"].int self.rateRemaining = headers["Rate-Remaining"].int } } }
struct ErrorResponse: ErrorType { var error: NSError var response: NSHTTPURLResponse? init(error: NSError, response: NSHTTPURLResponse? = nil) { self.nsError = error self.response = response } }
Make original struct for easy handling.
BrightFutures & SwiftyJSON
// AppManager.swift
func getItems(pageInfo: PageInfo, query: String?) -> PageResponseFuture { let promise = Promise<PageResponse, ErrorResponse>() AlamofireClient.requestJSON(QiitaAPIRouter.Items(pageInfo: pageInfo, query: query)) .onSuccess { (result: JSONResponse) in let pageResponse = PageResponse(json: result.json, pageInfo: pageInfo, response: result.response!)
promise.success(pageResponse) } .onFailure { (errorResponse: ErrorResponse) in promise.failure(errorResponse) } return promise.future }
struct PageResponse { var json: JSON var totalCount: Int? var pageInfo: PageInfo init(json: JSON, pageInfo: PageInfo, response: NSHTTPURLResponse?) { self.json = json self.pageInfo = pageInfo if let response = response { let headers = JSON(response.allHeaderFields) self.totalCount = headers["Total-Count"].intValue } } }
typealias PageResponseFuture = Future<PageResponse, ErrorResponse>
Inject something before network returns.
