1. @sergiocarrilho Sergio Carrilho ソニーのKMP/CMP挑戦記 Sony’s Story with KMP/CMP TechLead | Sony
2. iOSエンジニアの可能性を広げる ソニーがKotlin/Compose Multiplatformに挑戦した理由 （あなたもぜひ）
3. iOSエンジニアの可能性を広げる ソニーがKotlin/Compose Multiplatformに挑戦した理由 （あなたもぜひ????）
4. 01 Why KMP/CMP 02 How we did it? 03 Should you do it?
7. >>Next project...
8. UI UI Biz Logic Biz Logic Until now
9. UI UI Goal Biz Logic
10. Sensing trigger Context Action data
11. Requirement 1.iOS & Android 2.High performance 3.Platform APIs (BLE, GPS, BG...)
12. Why
13. UI UI Business/Domain Data/Core iOS APIs Android APIs iOS Android KMP (shared)
14. Native UIs Bytecode LLVM Kotlin Multiplatform JVM Kotlin/Native
15. Bytecode LLVM Kotlin Multiplatform JVM Kotlin/Native iOS framework
16. expect fun / class actual fun / class actual fun / class Common
17. expect fun randomUUID(): String import java.util.* actual fun randomUUID() = UUID.randomUUID().toString() import platform.Foundation.NSUUID actual fun randomUUID(): String = NSUUID().UUIDString() Common
18. HOW Part 2
19. Hexagonal Architecture
21. Core: Biz logic, platform agnostic
22. Core: Biz logic, platform agnostic Platform: iOS/Android
23. Platform: iOS/Android Core: Biz logic, platform agnostic External / cloud: Sensor, biz intelligence
24. Platform: iOS/Android Core: Biz logic, platform agnostic Adapters External / cloud: Sensor, biz intelligence

35. Maps
37. Results
38. 55 55% % iOS iOS users P E R P L AT FO R M
39. Code L A N G U AG E D I ST. 80 20 Multiplatform Native
40. SHOULD YOU DO IT? Part 3
41. it depends...
42. Stick to iOS if... You want full iOS UX Target market is iOS
43. Try KMP/CMP if... iOS Dev → Mobile Dev Expand to other platforms A lot of common biz logic (>10%)
44. start
47. Kotlin/Swift Mapping Kotlin Swift Class Class Interface Protocol Constructor Initializer Property Property Method Method null nil Kotlin Swift Unit Void String String List Array Set Set Map Dictionary Function type Function type
48. suspend vs async
50. iOS/Android dev Development Duplication Unification Mobile dev Users
51. TRY IT just
