missing dependant sourcekite tool, please configure correct "swift.path.sourcekite"

Hi, I am unable to use this extension. I am running VS Code on macOS High Sierra, and i get the above error message. This is the output:

justinmoser/.vscode/extensions/vknabel.vscode-swift-development-environment-2.1.2/out/src/server/sourcekites.js:43
        throw err;
        ^

Error: spawn swift build -Xswiftc -framework -Xswiftc sourcekitd -Xswiftc -F -Xswiftc /Library/Developer/Toolchains/swift-latest.xctoolchain/usr/lib -Xlinker -rpath -Xlinker /Library/Developer/Toolchains/swift-latest.xctoolchain/usr/lib ENOENT

[Error - 18:10:48] Connection to server got closed. Server will not be restarted.

I have run the build / link command as instructed on the sourcekite repo page. From my root directory (HD root):

> git clone https://github.com/jinmingjian/sourcekite.git > cd sourcekite > swift build -Xswiftc -framework -Xswiftc sourcekitd -Xswiftc -F -Xswiftc /Library/Developer/Toolchains/swift-latest.xctoolchain/usr/lib -Xlinker -rpath -Xlinker /Library/Developer/Toolchains/swift-latest.xctoolchain/usr/lib

and then added this to my settings.json file, under the user settings tab:

"swift.path.sourcekite": "/Users/justinmoser/sourcekite/.build/debug/sourcekite"

I also get the message:

Incorrect type. Expected "array".

in the launch.json file on this key:

"configurations": "sde.commands.debug.provideInitialConfigurations"
