-## Setting the sdk path
-
-Since Xcode 11, SourceKit needs to know which sdk is being used. For the purposes of this plugin, it doesn't seem to matter which platform this sdk belongs to so this can just be the macOS sdk. To list the macOS SDKs bundled in Xcode:
-
-```
-$ ls /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs

-You will need to copy the full path of one of these SDKs to the companion app.
-
-If you have more that one Xcode installed you will also need to make sure the SDK is belongs to the right version of Xcode. For example, the SDKs in Xcode 10 do not work with SourceKit in Xcode 11.
