Kotlin 1.5 Event Materials and the 10 Most Interesting Questions from the Q&A

Top 10 questions (answers in the blogpost)

1. Do you think large monolith Kotlin projects will also get a performance boost in future versions?
2. What’s the team vision on compiler plugins in the long run?
3. Are there plans to support WebAssembly in Jetpack Compose for Web?
4. Any news on the Kotlin Native garbage collector rewrite?
5. With Java adopting many features that Kotlin has or had, how will Kotlin stand out against Java after JDK17 is released?
6. What is the ultimate goal of Kotlin? Is it something like ‘Write in one language, used in everywhere’? (I thought this because of Kotlin Multiplatform, KMM, Compose for Web, Desktop, etc.)
7. Have you already tried Project Loom in Coroutines implementation?
8. As a tech lead with experience of leading a real world project with KMM, it’s harder to get iOS developers to accept this stack. This would be easier with AppCode integration, so you have such plans to support the iOS developer experience further?
9. Are (or will be) there any tools to access compiler and analyzer api for external usage? The only way now is using Kotlin compiler source code itself.
10. Why main() isn’t use in Android development?

📦 Kotlin 1.5.20-RC

– Parallel compilation of Kotlin sources is controlled by —parallel Gradle property. The kotlin.parallel.tasks.in.project property is deprecated.

– Aligned behavior of stdlib functions isLowerCase`/ `isUpperCase and digitToInt across platforms.

– Kotlin/Native: opt-in export of KDoc comments to the generated Objective-C headers with the -Xexport-kdoc compiler option.
