While there are many scripting languages available to create command line tools, creating binary executables has many benefits. Specially when you can write them in Swift.
These are the minimum steps to create a new command line tool and run it:
$ mkdir mycommandlinetool $ cd mycommandlinetool $ swift package init --type executable $ swift run Hello world!
To generate an Xcode project, you can run:
$ swift package generate-xcodeproj generated: ./mycommandlinetool.xcodeproj
Keep this command handy, as you will need to regenerate the Xcode project when adding new dependencies to the
