KDoctor is a command-line tool that helps to set up the environment for Kotlin Multiplatform Mobile app development.


KDoctor ensures that all required components are properly installed and ready for use.
If something is missed or not configured Kdoctor highlights the problem and suggests how to fix the problem.

KDoctor runs the following diagnostics:

  • System – checks operating system version
  • JDK – checks that JDK installation and JAVA_HOME setting
  • Android Studio – checks Android Studio installation, Kotlin and Kotlin Multiplatform Mobile plugins
  • Xcode – checks Xcode installation and setup
  • Cocoapods – checks ruby environment, cocoapods and cocoapods-generate gems installation


KDoctor works on macOS only.

If KDoctor notifies that there are problems, please review the report:

KDoctor has diagnosed one or more problems while checking your environment.
Please check the output for problem description and possible solutions.

Check the results of each diagnostic. There are 3 possible statuses:

  • [v] – Success
  • – Failure
  • [!] – Warning

Pay the most attention to the failed diagnostics ([x]) and look for messages that start with * for problem description and potential solution.

It is also worth checking diagnostics with warnings ([!]) and even successful messages as they may contain useful notes and tips.
