Setup

Create the image where your Dockerfile and fibonacci.swift are located.

docker build -t swift .

Usage

Run the swift container and then run your program inside the container

docker run -it swift /bin/bash

or just

docker run -it swift

after you are inside the Docker container you will get a prompt like this:

just run

swift fibonacci.swift

the result will be

    } else {
        return fibonacci(i: i - 1) + fibonacci(i: i - 2)
    }
