Hello! I received this error "SourceKittenFramework/library_wrapper.swift:31: Fatal error: Loading sourcekitdInProc.framework/Versions/A/sourcekitdInProc failed", when wrote fix command "swiftlint --fix".

Update and reinstall aren't help me.

On macOS, make sure Xcode is installed. See #1466 (comment) for help.

This also occurs when using a nightly/snapshot toolchain. (tested with latest Swift 5.10 Development Toolchain).

This also occurs when using a nightly/snapshot toolchain. (tested with latest Swift 5.10 Development Toolchain).

This fixed it for me. I had to remove the Swift 6.0 snapshot toolchain.

This should be reopened.

Also seeing this after downloading the Xcode 12.6 RC. Tried removing and reinstalling with no luck.

I'm on MacOS Sequoia 15.1.1 (24B91).

I had this problem when used xcodes in terminal. My version of Xcode 16.1 was marked as "installed". Then I opened AppStore and downloaded Xcode app from there. And after this problem solved. And xcodes it terminal now shows "installed, selected". Maybe it is not necessary to download app from AppStore and only type command it terminal (xcodes select) but in mine case only new app download helped.
P.S. after install Xcode from AppStore, xcodes in terminal showed something like this:
xcodes installed
16.1 (16B40) (Selected) /Applications/Xcode.app
16.1 (16B40) /Applications/Xcode-16.1.0.app

So it seems was an issue in Xcodes duplicates. And command in terminal "xcodes uninstall 16.1.0" erased unnecessary one.
After this i`ve got this list
xcodes installed
16.1 (16B40) (Selected) /Applications/Xcode.app

And now everything works fine

@ognerub so it looks like we cannot have 15.4 and 16.1 at the same time?

[ognerub]

In truth after update to Sequoia I`ve deleted XCode 15.3 from xcodes, and now use only version 16.1.
But you can try)

Hey folks! I also just encountered this error message and found this issue while looking for an answer.

Doing this solved it for me: #1466 (comment)
