What is Kotlin 2.2?

Kotlin is a popular programming language created by JetBrains. It helps developers build Android apps and other software in a simple way. Kotlin 2.2 is the latest update introduced during KotlinConf 2025. It adds new features and improvements to make the language easier and faster for users.

Main Features and Changes in Kotlin 2.2 Features

The new update includes these main improvements:

• Faster code compilation speed
• Better support for multiplatform projects
• Simplified syntax for easier coding
• Improved code readability and maintainability

These features help developers write clean, efficient code quickly. With faster compiling, applications can be built and tested more efficiently. Better support for different platforms means Kotlin can run smoothly everywhere, from mobile phones to desktop computers.

Introducing Amper – The New Build System

Alongside Kotlin 2.2, JetBrains announced a new build system called Amper. A build system helps to turn source code into working software. Previously, Kotlin mostly used Gradle. Amper offers a simpler, faster alternative for Kotlin developers.

Why Choose Amper?

Amper offers several benefits for users:

• Reduced setup time compared to Gradle
• Easy-to-understand settings for new developers
• Faster project build times improving productivity
• Built specifically to work smoothly with Kotlin

JetBrains created Amper to help developers save time. Projects built with Amper start quicker and have fewer errors during setup. With Amper’s simple approach, programmers can use their time on actual coding rather than on configuring the build system.

JetBrains’ New AI Tools Released at KotlinConf

Artificial Intelligence (AI) is becoming more important for software development. JetBrains introduced new AI tools to support Kotlin developers at KotlinConf 2025. These tools use AI technology to help developers write and optimize code more quickly.

Main AI Tools Announced

JetBrains’ new AI-powered tools include:

• AI Code Completion Tool
• Code Optimization Assistant
• Automatic Error Detection and Correction

AI Code Completion Tool – Kotlin 2.2 Features

This tool automatically predicts and suggests pieces of code as users type. It saves time by providing accurate suggestions based on existing coding patterns. The AI learns from previously written Kotlin code and helps developers write error-free programs.

Code Optimization Assistant

This AI software reviews existing Kotlin code and suggests improvements. It shows ways to make the code run faster or use fewer resources. Developers can benefit from having more efficient programs without manually checking every line themselves.

Automatic Error Detection and Correction

The tool scans Kotlin code as users type and identifies logic mistakes. It offers detailed advice on fixing these errors quickly. Early error detection helps reduce time spent hunting down problems, allowing developers to focus on important tasks.

Developer Feedback from KotlinConf 2025

Developers attending KotlinConf had positive reactions to Kotlin 2.2, Amper, and the new AI tools. Most of them shared how these updates will help them build apps more easily. They welcomed clearer syntax, simpler builds, and useful AI features.

Feedback Highlights from Users

Some key comments from developers included:

• Kotlin 2.2 will speed up their daily coding workflow
• Amper offers the perfect balance between simplicity and effectiveness
• AI tools significantly reduce time spent on coding routine tasks
• Automatic error detection greatly increases confidence during coding

Impact of Kotlin Updates on Android App Development

Android developers commonly use Kotlin to build apps. These latest updates offer big improvements to the Android app development process. Kotlin 2.2, Amper, and the AI tools all aim to streamline app creation, saving developers both time and effort.

Benefits for Android App Developers

• Faster project setup and development stages
• Easier code maintenance and improvement
• Advanced AI-driven solutions to common coding challenges
• Less time wasted fixing errors, leading to quicker app releases

These updates make Kotlin even more attractive for companies seeking efficient development. Both small businesses and large tech companies benefit from shorter development cycles and fewer bugs.

How Kotlin is Keeping Up with Developer Needs

JetBrains actively listens to its users. Kotlin 2.2 demonstrates a clear response to user feedback, addressing common frustrations and requests. The company understands that solving practical coding problems helps developers produce better apps.

What to Expect Next from Kotlin

Looking forward, JetBrains plans:

• Regular updates to Kotlin for continuous improvements
• Further enhancements of the Amper build system based on user needs
• More advanced AI-powered tools for better programming results

JetBrains promises continued support for Kotlin users. The company ensures that upcoming features directly address real-world issues faced by developers today.
