# 1. Build app
# 2. Hot reload application
#    - Watch the current directory ("-w ./")
#    - Only watch for files with ".swift" extentsion ("-e swift")
#    - Ignore build so that it does not hot reload recursively ("--ignore ./.build")
#    - Specify execution command, it will stop the app and rerun this command each time something changes ("'swift run App serve --hostname 0.0.0.0 --port 8080'")
