JetBrains and Touchlab partner to drive Kotlin Multiplatform adoption in 2020 At JetBrains, we’re very delighted to partner with our good friends at Touchlab to increase the adoption of Kotlin Multiplatform Mobile technology in 2020 and beyond. Touchlab has released a toolkit for getting started with Kotlin Multiplatform Mobile technology. It’s a self-contained GitHub project that you can use as a starting point or for evaluating the technology. We had the chance to review it before its general release and can say that we’re excited to share it with the Kotlin Multiplatform community! The f

Ktor 1.3 was released recently, and we’re happy to share the details with you in this blog post. Ktor consists of two parts: the server engine and a flexible asynchronous HTTP client. The current release focuses mainly on the HTTP client. Here you can find the complete changelog for this release. The client is a multiplatform library that supports JVM, JS, Android, and iOS and is now often used in cross-platform mobile applications. Our main goal for the next releases is to make the server engine multiplatform, too. The other areas we’re going to work on are: Improving integration w

We are happy to announce the new and improved Kotlin/Native plugin for AppCode 2019.1! Enjoy working on Kotlin, Swift, and Objective-C projects for macOS and iOS inside the same IDE. New to AppCode?

Summer may be almost over, but our Kotlin/Native team has been breaking a sweat to give you the Kotlin/Native v0.9 release... and here it is! Don't be fooled by the numbering – this is a major (and breaking) release of our compiler toolchain, Gradle plugin, and IDE plugin.

Greetings Kotlin fans! Ever since we announced interoperability with Objective-C for Kotlin/Native, we’ve been getting lots of questions about IDE support that would allow working on projects that mix Kotlin/Native and Swift/Objective-C. Today we are happy to announce that we are working on a Kotlin/Native plugin for AppCode! AppCode is our macOS-only IDE designed for iOS/macOS developers. It already supports the Xcode project model, running and debugging in simulators and on devices, and offers extensive support for Objective-C and Swift. So, it felt natural to add Kotlin/Native support to

We’re happy to announce the release of Kotlin/Native v0.5, Christmas edition! This release adds support for using Kotlin/Native code from C, Objective-C and Swift, supports development using iOS simulator, along with LLVM 5 support and creating WebAssembly from Linux and Windows hosts. (more…)

Today, at the Google I/O keynote, the Android team announced first-class support for Kotlin. We believe this is a great step for Kotlin, and fantastic news for Android developers as well as the rest of our community. We’re thrilled with the opportunities this opens up. For Android developers, Kotlin support is a chance to use a modern and powerful language, helping solve common headaches such as runtime exceptions and source code verbosity. Kotlin is easy to get started with and can be gradually introduced into existing projects, which means that your existing skills and technology investment

This is a guest blog post from Antonio Leiva — Android engineer, trainer and author of the "Kotlin for Android Developers" book. We’re all really excited about the release of Kotlin 1.1. The new features this release includes are extremely useful for Java developers and lead JVM development to a new world of possibilities. But these new features, such as coroutines, or type aliases (to put a couple of examples), look like science fiction for Android developers. We’re still stuck in an ancient Java 6 with little improvements that forces us to develop in ways almost forgotten for most devel

Introduction One of the most interesting pieces of news we've all seen recently is Google announcing (limited) Java 8 support for Android N with the Jack compiler for Java. Naturally, our users are curious about how these news affect them, and this blog post outlines our plans and our vision for Kotlin’s place in the Android development world in light of Google’s announcements.

This post is largely outdated. Please refer to the kapt documentation. We announced kapt, an Annotation Processing Tool for Kotlin, some time ago, and discussed its limitations. Now most of the limitations are going away with the updated version of kapt that is available as a 0.1-SNAPSHOT preview. (more…)
