Installation describes how to set up Noctule and Swift.

System Requirements#

JetBrains IDEs 2025.3 – 2026.2   Android Studio Panda or later   Swift 6.2 or later

Noctule requires a JetBrains IDE, version 2025.3 or later. Alternatively, you can use Noctule with Android Studio Panda or later.

macOS, Linux and Windows are supported.

Swift 6.2 or later or later must be installed on your system to support all features of Noctule. Earlier versions may work but are not officially supported.

Current Limitations#

Noctule is still under active development and not yet a complete Swift IDE. If you need a new feature, please report this as a GitHub issue or start a new discussion there.

The following features are not yet supported, but planned for the future:

• Xcode integration. Version 2.0 will provide basic integration with XCode projects. Noctule 2.0 is currently only available for 2026.2 IDEs for better testing before it’s made available for all supported JetBrains IDEs.
