Typically Swift source code files are given the suffix:

  • .swift (ex: Hello.swift)

Running Locally using Terminal:

Sometimes it is more convenient to run Swift code in the terminal.

On the Mac, it’s called the Terminal. On Windows, it’s called the Command Prompt.

Let’s see how we can do it in macOS terminal:

$ swift --version


$ swiftc Hello.swift

swiftc and the source file name.


$ ./Hello

./ and the executable file name.
