1. @ c a s s i e n d IOS WITH CONTINUOUS DELIVERY Cassie Shum
4. Continuous Deployment Continuous Delivery can deploy to production do deploy to production 㱺
5. •User feedback •Believable •Reduced deployment risk
6. 2 month’s work Many LOC Risk 1 day’s work Few LOC Risk •User feedback •Believable •Reduced deployment risk
7. scope time target done •User feedback •Believable •Reduced deployment risk
8. Customer developent Agile product development Eric Ries, “The Lean Startup” http://bit.ly/8ZoX5F •User feedback •Believable •Reduced deployment risk
9. Release Build Deploy Test
10. Release Build Deploy Test measure success via cycle time
11. Release Build Deploy Test
12. Design Patterns Clean Code Build
13. Controller Model View Uses Sees Updates Manipulates
14. Controller Model View Uses Sees Updates Manipulates • MVVM • Clean Architecture • VIPER
15. MODEL-VIEW-VIEW-MODEL (MVVM) • Data binding • View Model • exposing methods, commands, and other methods to maintain state of view • manipulate model in result of view actions • works with model objects explicitly
16. • Uncle Bob • Better decoupling • Better reusability • Many more layers CLEAN ARCHITECTURE
17. • clean architecture • big projects • Single Responsibility Principle VIPER
20. •SwiftLint/Tailor •OCLint •CPD •Static Analysis from XCode •FBinfer

30. CONTINUOUS INTEGRATION compile/unit tests functional test user acceptance test staging … increasing confidence in production readiness artifact respository artifact respository artifact respository artifact respository Pipeline stages = feedback opportunities
31. CONTINUOUS INTEGRATION
32. JEZ HUMBLE’S 3-STEP TEST 1. Every developer commits to master / trunk every day 2. Every commit triggers build and test 3. Failures usually fixed in minutes
