Not able to run the LSP

[Stijn Willems]

When trying to setup visual studio code like in the ReadMe I got errors that it could not run the sourcekit-lsp. I'm trying this on Catalina.

Then I just tried to run it. But this failed with message below. Any idea's?

swift-LOCAL-2020-02-15-a.xctoolchain ./usr/bin/sourcekit-lsp
