  10. Past Architecture Problems
    • 2 tasks in Coordinator
    • View Transition
    • Dependency Injection
    • hard to test
    • cannot replace with stub objects

  13. 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)

  15. Development Workflow
    situation workflow
    make service make service
    -> update components
    make view make VC & VM
    -> make function at ViewFactory
    make transition update coordinator
    15

    View full-size slide

  16. Result
    • Coordinator: only view transition
    • Factory & Components: Dependency Injection
    • No Singleton!
    • App / Components / UI is good for object organizing (not
    only folder structures)
