App Architecture by Manual DI @yoshikuni_kato SwiftѪձ vol23 2017/09/20 1
Who am I ? • Yoshikuni KatoʢՃ౻༝܇ʣ @yoshikuni_kato • iOS
Engineerʢ2.5 yearsʣ • Yahoo! Japan -> OHAKO • Radi-Hey → 2
Presentation at iOSDC 2017 1 1 https://speakerdeck.com/yoching/guan-shu-woyin-shu-tositedu-sushu-kifang-falsepointo 3
Self Introduction - Interests • Software Design • App Architecture
Patterns • Test • Functional Reactive Programming (ReactiveSwift) • Functional Approach • UI Implementation • AutoLayout (priority / ...) • UIStackView • UIViewPropertyAnimator • Custom Transition 4
Self Introduction - Few experiences • Older OS • Objective-C
• Maintenance / Operation • DB Management • CoreAnimation / CoreGraphics 5
App Architecture by Manual DI 6
Sample Code • yoching/iOSAppArchitectureSample 2 2 https://github.com/yoching/iOSAppArchitectureSample 7
Past Architecture • MVVM-C • ը໘ભҠͷཧͱMVVM 3 • Coordinatorύλʔϯͷ࣮ફ 4

Past Architecture Problems • 2 tasks in Coordinator • View
Transition • Dependency Injection • hard to test • cannot replace with stub objects 10
Inspirations • Minimizing Decision Fatigue to Improve Team Productivity @
try! swift 2017 5 • Application / UI / Components (Project Organization) • ґଘੑͷೖʢDependency Injection) @ wikipedia 6 • खಈͰͷDI / ࣗಈతͳDI • Deep Linking at Kickstarter @ SwiftTalk 7 • Routing logics 7 https://talk.objc.io/episodes/S01E49-deep-linking-at-kickstarter 6 https://ja.wikipedia.org/wiki/%E4%BE%9D%E5%AD%98%E6%80%A7%E3%81%AE%E6%B3%A8%E5%85%A5 5 https://www.slideshare.net/DerekLee/minimizing-decision-fatigue-to-improve-team-productivity 11
Architecture 12
2 Types of Objects • Runtime Objects • several objects
for app runtime • testable (all dependencies are injected) • Dependency Management • doing Dependency Injection • no need to test (like setting file) 13
Sample Code • yoching/iOSAppArchitectureSample 2 2 https://github.com/yoching/iOSAppArchitectureSample 14
Development Workflow situation workflow make service make service -> update
components make view make VC & VM -> make function at ViewFactory make transition update coordinator 15
Result • Coordinator: only view transition • Factory & Components:
Dependency Injection • No Singleton! • App / Components / UI is good for object organizing (not only folder structures) 16
Thank you! 17
