Noctule 2.0, a new major version

June 27, 2026

Noctule 2.0 adds support for Xcode projects and remote development among a large number of improvements, bug fixes, and updates.

Refer to the detailed changelog for the details, but you can find a summary of the changes below.

Most Important Changes#

Initial support for Xcode development with xcode-build-server integration, build support with xcodebuild, run configurations for building and deploying to a simulator, a tool window to manage simulators, a new project view for Xcode projects, and more.
Support for JetBrains Remote development. This allows, for example, executing the IDE backend on a Mac and the frontend on your preferred platform. All features, including managing Xcode simulators, are supported in remote development mode.

2.0 prepares for stable settings. You may have to reconfigure your toolchain, custom settings for Swift workspace directories, and perhaps a few more settings of Noctule. Most users won’t have any customized directory settings, though.
2025.3 and later are supported now. Support for earlier versions was dropped.

The following features are not yet available but are planned for the next releases:

Support for “View > Type Info”.
Support for “Navigate > Type Declaration” and “View > Quick Type Definition” with a Swift 6.4 toolchain or later.
Navigation, find usages, and similar features were not working inside *.swiftinterface files of Swift base libraries.
The Swift lexer has been made incremental again, which should improve performance and editor responsiveness.

Support to detect and open new projects from project.xcworkspace/ or project.xcodeproj/ directories.
Support building a project or workspace with actions of the “Build” menu.
Integration with “xcode-build-server” to integrate Xcode projects with SourceKit LSP.
Run configurations to execute xcodebuild and to deploy an application to a simulator.
Dropdowns similar to Xcode’s UI are shown in the main toolbar to allow choosing the current scheme and destination for your development. xcode-build-server and also Xcode’s own command line tooling are built around schemes and destinations.
Tool window “Xcode simulators” showing the available simulators. Actions like “Boot” or “Shutdown” are available on items shown in the tree.

The build output is now shown in the IDE’s own “Build” tool window. Previously, Noctule’s build output was shown in a separate “Noctule Logs” tool window.
Building with “xcodebuild” is integrating now with the “Build” menu actions.
