    BLESSED, a Bluetooth Low Energy (BLE) library for Android

    BLESSED is a very compact Bluetooth Low Energy (BLE) library for Android 5 and higher, that makes working with BLE on Android very easy.

    Scrimage

    Scrimage

    JVM - Java, Kotlin, Scala image processing library

    ...The aim of this library is to provide a simple and concise way to do common image operations, such as resizing to fit a required width and height, converting between formats, applying filters, and so on. It is easy to use from any language on the JVM. A typical use case for this library would be creating thumbnails of images uploaded by users in a web app, bounding a set of product images so that they all have the same dimensions, optimizing PNG uploads by users to apply maximum compression, or applying a grayscale filter in a print application.

    KSP

    KSP

    Kotlin Symbol Processing API

    KSP is Kotlin’s lightweight, idiomatic alternative to Java annotation processing that gives compile-time access to Kotlin program structure. Rather than forcing Kotlin through Java’s annotation APIs, it exposes Kotlin-first symbols—classes, functions, properties, types—so processors can generate code efficiently. The design dramatically reduces incremental build overhead by operating directly on symbols without compiling stubs, which speeds up large multi-module projects. Processors run as Gradle plugins, participate in incremental builds, and can target common use cases like DI bindings, JSON adapters, or UI glue code. ...

We believe that for Mavericks to be successful, it must be effective for building everything from the simplest of screens to the most complex in our app.

    SKIE

    SKIE

    Swift Kotlin Interface Enhancer

    One of the main downsides of Kotlin Multiplatform is the lack of a direct Swift interop. Without it, Swift can communicate with Kotlin only indirectly - through Objective-C. While this approach works, it has many limitations, so Kotlin loses support for many of its language features. SKIE (pronounced as sky) is a special Kotlin native compiler plugin that brings back support for some of these features by modifying the Xcode Framework produced by the Kotlin compiler. Thanks to that, you don't have to change how you distribute and consume your Kotlin Multiplatform frameworks.

    Lightweight Multiplatform logging framework for Kotlin

    ...Version 5 is not backward compatible with previous versions (v.3, v.2, v.1). Group id (in maven) and package names changed. It is possible to use both version 5 and previous versions side-by-side so some of the code from the old version and some new. It is also possible to have libs using old version and use the new version (and vice-versa). After seeing many questions like the Idiomatic way of logging in Kotlin and Best practices for loggers, it seems like there should be a standard for logging and obtaining a logger in Kotlin.
