Cannot get Delve to work with VSCode anymore

[carlca]

VSCode Insiders 1.18.0
macOS 10.13.0 High Sierra
Delve Version: 1.0.0-rc.1
Golang 1.9.1

Hello, I no longer seem to be able to debug my Golang code using Delve. It used to work but after a few new versions of VSCode, something's gone wrong. My launch.json is as follows:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [        
        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "remotePath": "",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "${workspaceRoot}",
            "env": { 
                "GOPATH": "/Users/carlca/Code/go" 
            },
            "args": [],
            "showLog": true
        }
    ]
}

I added the GOPATH info into the "env" setting and that seemed to sort out the path issue. I notice though that my Debug Console windows is showing:

2017/10/13 13:50:16 server.go:73: Using API v1
2017/10/13 13:50:16 debugger.go:97: launching process with args: [/Users/carlca/code/go/src/gitlab.com/hackebrot/tweets/debug]
could not launch process: exec: "lldb-server": executable file not found in $PATH
Process exiting with code: 1

I don't see why it's complaining about lldb-server when I would have thought that DLV should be the debugging executable.

Thanks in advance for any help!

I checked the issue #947 and ran xcode-select --install. That seems to have fixed it.
