9. Features • Kotlin Source recognition and coloring • Add breakpoints • Interactive debugging
10. Xcode Demo!
11. Dev Version about 1/3 slower than earlier version
12. 3 Main Pieces
13. Kotlin.xcplugindata tells Xcode that *.kt is source
14. Kotlin.xclangspec color file (tweaked from Java, TBH)
15. konan_lldb.py lldb formatter (where the magic happens)
21. Adding Kotlin Files to Xcode spoilers: the hard part
22. xcode doesn’t “see” your folders
23. you must add them
24. Source or Resource?
25. Options
26. 1) Manually Add Them spoiler: meh
27. 2) Gradle Plugin better
28. xcode { projectPath = "../../iosApp/iosApp.xcodeproj" target = "iosApp" } apply plugin: 'co.touchlab.kotlinxcodesync'
30. Work in progress!
31. 3) Cocoapods probably best option in near future…
32. https://github.com/touchlab/DroidconKotlin/
33. AppCode?
35. AppCode Demo!
36. PR Ready! almost
39. What’s Next?
40. Performance!
41. Better Formats
42. this is a map?
43. Other Stuff
44. RUNTIME_USED int32_t Konan_DebugObjectToUtf8Array(KRef obj, char* buffer, int bufferSize); // Print to console string representation of an object. RUNTIME_USED int32_t Konan_DebugPrint(KRef obj); // Returns 1 if obj refers to an array, string or binary blob and 0 otherwise. RUNTIME_USED int Konan_DebugIsArray(KRef obj); // Returns number of fields in an objects, or elements in an array. RUNTIME_USED int Konan_DebugGetFieldCount(KRef obj); // Compute type of field or an array element at the index, or 0, if incorrect, // see Konan_RuntimeType. RUNTIME_USED int Konan_DebugGetFieldType(KRef obj, int index); // Compute address of field or an array element at the index, or null, if incorrect. RUNTIME_USED void* Konan_DebugGetFieldAddress(KRef obj, int index); // Compute address of field or an array element at the index, or null, if incorrect. RUNTIME_USED const char* Konan_DebugGetFieldName(KRef obj, int index);
