Welcome to the Kotlin roadmap, where we're excited to share our priorities and plans for the future of swift app development. In this article, we'll give you an insider's look at what we're working on and what you can expect from the JetBrains team.

Key Priorities

Our main focus areas are designed to help you build better, faster, and more scalable apps with Kotlin. Here's a snapshot of our key priorities:

  • Language Evolution: We're committed to keeping Kotlin both pragmatic and expressive by introducing meaningful language improvements that emphasize semantics over syntax changes.
  • Multiplatform: Our goal is to build the foundation for modern multiplatform apps, including solid iOS support, mature web targets, and reliable IDE tooling.
  • Staying Agnostic: We're dedicated to supporting developers no matter their tools or targets.
  • Ecosystem Support: Simplifying the development and publication process for Kotlin libraries, tools, and frameworks is a top priority.
