18. Why?
19. How?
22. import java.util.ArrayList object Main { @JvmStatic fun main(args: Array<String>) { val names = ArrayList<String>() names.add("Shawn") names.add("Matt") names.add("Alec") names.add("James") names.add("Egor") names.forEach(System.out::println) } }
23. import java.util.ArrayList object Main { @JvmStatic fun main(args: Array<String>) { val names = ArrayList<String>() names.add("Shawn") names.add("Matt") names.add("Alec") names.add("James") names.add("Egor") names.forEach(System.out::println) } }
24. import java.util.ArrayList object Main { @JvmStatic fun main(args: Array<String>) { val names = ArrayList<String>() names.add("Shawn") names.add("Matt") names.add("Alec") names.add("James") names.add("Egor") names.forEach(System.out::println) }A }
25. fun main(args: Array<String>) { val names = ArrayList<String>() names.add("Shawn") names.add("Matt") names.add("Alec") names.add("James") names.add("Egor") names.forEach(::println) }A
27. Kotlin Stdlib
28. Kotlin Stdlib (And things built using kotlin stdlb)
29. Kotlin Multiplatform
30. Platform Agnostic Code
32. apply plugin: 'konan'
33. konanArtifacts { program('foo') // executable 'foo' library('bar') // library 'bar' bitcode('baz') // bitcode file 'baz' interop('qux') // interoperability dynamic('quux') // dynamic library frameworkA('quuux')A//AObjective-C }A
34. konanArtifacts { frameworkA('quuux')A//AObjective-C }A
35. iOS
36. • No swift header support • Enums • Generics • Value Types • Garbage Collection
37. Garbage Collection
38. Kotlin/Native
