We’ve just updated the Kotlin Roadmap to reflect our plans for Kotlin 1.7.0 and beyond! If you just want a quick overview of what’s going on without going into the details, you can get the gist of what we are working on in this blog post, which covers the seven most notable highlights.

Maintaining Gradle build setups to have a reliable and reproducible build process is not always easy. In this blog post, we’ll tell you about one of the Gradle features that Kotlin has recently added support for – JVM toolchain. This feature provides a simple way to have a reproducible build independent from the user JDK, plus it reduces the complexity of working with multiple JDKs. What is the

The Kotlin Online Event is over. But we thought we’d give a quick recap of the two server-side talks: What’s New in Ktor 2.0 and Spring Native with Kotlin. In these presentations, Hadi Hariri and Sébastien Deleuze took us on a pair of deep dives into the multiplatform abilities of the frameworks. What's New in Ktor 2.0 This talk covered some of the exciting new things that are coming in Ktor

Kotlin was designed to be very similar to Java to make migration as smooth as possible. However, Kotlin was also designed to improve the developers' experience by providing a more expressive syntax and a more sophisticated type system. To take full advantage of the language and write more concise code, learning Kotlin idioms is a must. Without them, it is easy to fall back into old Java patterns.

Announcing a new series of webinars about Kotlin for server-side! These will take place between May 27 and June 17. Join the live sessions or watch the recordings later! In this five-webinar series, our speakers will host step-by-step live coding sessions to show you what kinds of benefits you can get from Kotlin for server-side and its rich ecosystem. Each webinar will include a Q&A sessio

We continue our series of Kotlin for server-side webinars. Between February 18 and March 18 we will host 4 webinars to explore applied software development with Kotlin on server-side through live-coding sessions. Speakers from JetBrains, VMware, Confluent, and Oracle will cover reactive programming, asynchronous applications with the Ktor framework, building microservices with Helidon, and other a

The KMM Plugin for Android Studio 0.3.0 was recently released! It comes with lots of new features and improvements that simplify the creation of new KMM projects and improve the process of developing iOS applications based on Kotlin Multiplatform Mobile.

In this video, Ekaterina Petrova discusses all the important changes that you can expect with KMM Beta, which will be available in Spring 2022. These changes include a new memory management approach for Kotlin/Native, improved Apple integration tooling, the hierarchical proj

When making a Kotlin Multiplatform Mobile plugin for AppCode, we focused on providing cross-language features that can work for any part of your project – be it a shared module or a native Android or iOS part. The first cross-language refactoring we introduced was the Rename refactoring: Safe Delete also works from the first plugin build, tracking usages of the shared code in all languages. W

Kotlin Multiplatform Mobile plugin for AppCode helps you develop applications for Android and iOS using the unified Gradle project model and provides cross-language code assistance. CocoaPods integration now works with the latest plugin version available in our plugin repository. Just add a Pod dependency to your shared module, sync the Gradle project, import the required module in your Swift or O

Introducing Multik 0.1 - a new, enhanced version of our multidimensional array library! You can check out the previous post to learn about the basic features and architecture of the library. In the new release, we added new methods from linear algebra, supported complex numbers and reading/writing .csv files, improved the performance and stability of existing functions, and added many more feat

KotlinDL 0.3 is available now on Maven Central with a variety of new features! New models in ModelHub (including the first Object Detection and Face Alignment models), the ability to fine-tune the Image Recognition models saved in ONNX format from Keras and PyTorch, the experimental high-level Kotlin API for image recognition, a lot of new layers contributed by the community members and many other changes.
