Kotlin 1.5.30 Is Now Available!

This post continues our “Idiomatic Kotlin” series and provides the solution for the Advent of Code Day 9* challenge. While solving it, we’ll look into different ways to manipulate lists in Kotlin. Day 9. Encoding error, part I We need to attack a weakness in data encrypted with the eXchange-Masking Addition System (XMAS)! The data is a list of numbers, and we need to find the first numbe

Kotlin Symbol Processing is an API to build lightweight compiler plugins. KSP provides a simplified compiler plugin API that leverages the power of Kotlin while keeping the learning curve to a minimum. And it is now Stable!

The Kotlin team has always relied on feedback from the community to make decisions about the future of the technology. You will always be the people who best know how to make Kotlin even more enjoyable to work with! That’s why a year ago we started a Kotlin Multiplatform Survey program to collect your feedback on sharing code with Kotlin Multiplatform, learn more about your use cases, and understa

We’ve been working on a new K2 Kotlin compiler for quite some time. The new compiler aims to speed up the development of new language features, unify all the platforms Kotlin supports, bring performance improvements, and provide an API for compiler extensions. The development of the Kotlin compiler started many years ago, and many things have changed since that time. For example, in Kotlin 1.0,

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

Like most startups, at the beginning of its journey Faire was looking for an efficient solution to base its tech stack on. Here is their story of starting with Java and migrating to Kotlin in a year.

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

One of the main benefits of Kotlin Multiplatform Mobile is its flexibility. You can use KMM in your existing or new projects, share different parts of your apps, and integrate with different UI frameworks. To find the best way to apply this flexibility in your project and maximize the benefits of using KMM, it can really help to look at how other projects have used it. Today we’ll look at the KMM

Hi everyone, We recently announced a new plugin for Kotlin Multiplatform Mobile development that helps you develop applications for Android and iOS using the unified Gradle project model and provides cross-language code assistance. Currently, this plugin is available only for AppCode, a paid IDE. We’ve decided to provide a way to try this plugin for free: just fill out this form to get four free

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.

KotlinDL 0.2 is available now on Maven Central with a variety of new features. New layers, a special Kotlin-idiomatic DSL for image preprocessing, a few types of Datasets, a great Model Zoo with support for the ResNet and MobileNet model families, and many more changes are now receiving a final polish.

This update of the Kotlin kernel for Jupyter Notebook primarily targets library authors and enables them to easily integrate Kotlin libraries with Jupyter notebooks. It also includes an upgrade of the Kotlin compiler to version 1.5.0, as well as bug fixes and performance improvements. pip installConda install The old way to add library integrations As you may know, it was already possible to inte

A new version of the Kotlin serialization library – 1.3.0 – is now available following the release of Kotlin 1.5.30. It mainly focuses on broadening the JSON serialization capabilities. Here are the most noticeable changes: Serializing and deserializing Java IO stream. You can now read and write JSON directly to network streams or files.More control over the encoding of default values. A new an

Kotlin Coroutines 1.5.0 delivers GlobalScope that is now marked as a delicate API, extensions for JUnit, the refined Channel API, and stabilized reactive integrations.

Today we’re exploring kotlinx-datetime 0.2.0 — a new version of the Kotlin library for working with dates and times.

kotlinx.serialization 1.2 is out! The latest version of our multiplatform serialization library brings a number of improvements – here are the highlights: JSON serialization is faster than ever before. Version 1.2 is up to twice as fast as previous versions when parsing JSON into type-safe Kotlin objects and turning Kotlin objects into their text representations. Kotlin 1.5 type system additi
