20. Powerful Swift OSSs.
• Dependency Manager: Carthage
• Networking: Alamofire
• JSON parser: SwiftyJSON
• Database: Realm
• Future(promise): BrightFutures
• View binding: SwiftBond
• Image loading: Kingfisher
• AutoLayout: SnapKit

21. Powerful Swift OSSs.
• Dependency Manager: Carthage Cocoapods
• Networking: Alamofire AFNetworking
• JSON parser: SwiftyJSON Mantle
• Database: Realm MagicalRecord/CoreData
• Future(promise): BrightFutures Bolts/PromiseKit
• View binding: SwiftBond ReactiveCocoa?
• Image loading: Kingfisher SDWebImage

Objective-C?

22. Core OSSs
• Carthage
• Alamofire
• BrightFutures
• SwiftyJSON

23. Carthage for all

24. Carthage
• Decentralized
• No .xcworkspace
• Clean & Simple
• Very Easy to
distribute
• Increasing
• Centralized
• .xcworkspace
• Easy to use
• Easy to distribute
• Already many
Cocoapods
https://github.com/Carthage/Carthage https://cocoapods.org/

25. Carthage
$ brew update
$ brew install carthage
$ cd move/to/app/root
$ vi Cartfile
github "Alamofire/Alamofire" == 3.1.2
wq
$ carthage update -platform ios

26. Carthage

27. Carthage
• Pros:
• Project remains clean.
• No build time.
• Cons:
• Library build time.
• Relatively fewer libraries.

28. If library doesn’t
compatible with
Carthage?

29. Fork!
Tweak!
(Pull Request!)

30. Just 4 steps
1. Create CocoaTouch
Framework
2. Add files to Framework
target
3. Make scheme shared
4. git push and tag in Github

31. I made 5 libraries
or more
Carthage Compatible
for Qolk.

32. Many Thanks.

33. Alamofire
SwiftyJSON
BrightFutures
cooperate.

34. BrightFutures
Networking system
API Server
App
SwiftyJSON

35. 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.

36. 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.

37. 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.

38. SwiftyJSON
final class Item: Object, ObjectCopyable {
dynamic var renderedBody = ""
dynamic var body = ""
dynamic var coediting = false
dynamic var createdAt = ""
dynamic var itemId = ""
dynamic var isPrivate = false
let tags = List<Tag>()
dynamic var title = ""
dynamic var updatedAt = ""
dynamic var url = ""
dynamic var user: User?
override static func primaryKey() -> String? {
return "itemId"
}
class func fromJSON(json: JSON) -> Item {
let item = Item()
item.renderedBody = json["rendered_body"].stringValue
item.body = json["body"].stringValue
item.coediting = json["coediting"].boolValue
item.createdAt = json["created_at"].stringValue
item.itemId = json["id"].stringValue
item.isPrivate = json["private"].boolValue
item.title = json["title"].stringValue
item.updatedAt = json["updated_at"].stringValue
item.url = json["url"].stringValue
item.user = User.fromJSON(json["user"])
for (_, subJson): (String, JSON) in json["tags"] {
item.tags.append(Tag.fromJSON(subJson))
}
return item
}
…
}
