While trying to debug Go scripts with Visual Studio, I stumbled upon issues configuring Delve on macOS. Delve is a full featured debugging tool for the Go programming language and Visual Studio Code seems to make us of it. Unfortunately the installation might not be as straightforward as described in the official installation documentation. The Brew installation fails while / after generating certificates:
==> Installing delve from go-delve/delve
==> Downloading https://github.com/derekparker/delve/archive/v1.0.0-rc.2.tar.gz
Already downloaded: /Users/beematik/Library/Caches/Homebrew/delve-1.0.0-rc.2.tar.gz
security: SecKeychainSearchCopyNext: The specified item could not be found in the keychain.
==> Generating dlv-cert
==> openssl req -new -newkey rsa:2048 -x509 -days 3650 -nodes -config dlv-cert.cfg -extensions codesign_reqext -batch -out dlv-cert.c
==> [SUDO] Installing dlv-cert as root
==> sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain dlv-cert.cer

Whatever the reason of this issue might be, there is a suitable workaround available:
cd $HOME/Library/Caches/Homebrew
tar xf delve-*.gz
cd delve-*
sh scripts/gencert.sh
# Type in your sudo password
brew install go-delve/delve/delve
