When the project is setup, most of the code you compose will be standard Kotlin. def file that supports multiple native platforms, you can use platform specific compiler and linker options,Īlthough the Cinterop tool can do the job in the context, Gradle is the best way to invoke it. Marshalling and translation are primarily done by the Klib. The cinterop tool processes these to generate klibs or Kotlin bindings that can easily be used to call the C code from Kotlin. def files that define the headers, compiler options, and linker options if you need to import additional C / ObjC headers. Many frameworks and libraries are supported out of the box, as mentioned above.Īs you would in any other Kotlin project, you can also draw in other dependencies via Gradle, Depending on the platform, the macosX64 call can be substituted, This configures tasks for creating a native Mac OS framework and checking it. The best way to get started is to build a new Kotlin Native project using IDE (CLion or IntelliJ).– Gradle multi-platform plugin for projects with Kotlin.Cinterop – A Kotlin Libraries (klib) generation tool from C/ObjC headers/libraries.In the tool chain, there are many moving pieces: Unique bindings for popular libraries have already been created on each platform. There is a simple integration into Gradle for this construction phase. Tools are available for translating C and Objective C (and thus, indirectly, Swift) libraries into Kotlin libraries and then using them directly from Kotlin. Linux (x86_64, arm32, MIPS, MIPS little endian, Raspberry Pi).Kotlin Native is only beta but supports it already. ![]() This enables the compilation of several high-level languages into native instructions unique to the platform. To compile any high-level language into this IR, front-end compilers can be written. A language-independent Intermediate Representation (IR) is compiled into different platform-specific native binaries by backend compilers. A set of modular compiler tools is LLVM (not an acronym….anymore 1). We can also easily build multi-platform libraries that are compiled on multiple platforms such as JVM, Android, JavaScript, Native MacOS, Native iOS, Native Windows, etc. The resulting binaries are NOT portable because the output is native, however the source may be. In cases where a virtual machine is not accessible or desirable, applications and libraries written in Kotlin Native run without a virtual machine and this is useful. We’ll address Kotlin Native in this article.Ī technology for compiling Kotlin code into native binaries is Kotlin/Native. The Kotlin teams also have the opportunity to use Kotlin for JavaScript and native environments, not to rest on their laurels. It’s also a fantastic JVM language, too (and in our opinion the best too). Use the library base artifact name, such as kotlinx-coroutines-core.The best language for writing Android applications is definitely Kotlin. ![]() If you use a multiplatform library and need to depend on the shared code, set the dependency only once in the shared source set. If you didn't use the Project Wizard to create your project, you can add the dependencies manually. When you create a multiplatform project, the Project Wizard automatically adds test dependencies to common and platform-specific source sets. The kotlin.test API is available for multiplatform tests. Learn how to change the default behavior. The Kotlin Gradle plugin will select the appropriate JVM standard library depending on the compilerOptions.jvmTarget compiler option of your Gradle build script. The version of the standard library is the same as the version of the kotlin-multiplatform plugin.įor platform-specific source sets, the corresponding platform-specific variant of the library is used, while a common standard library is added to the rest. Dependency on a Kotlin library Standard libraryĪ dependency on a standard library ( stdlib) in each source set is added automatically. Implementation 'com.example:my-library:1.0'Īlternatively, you can set dependencies at the top level.
