How to open .playground file in xcode via a terminal?

I just learned the basics of the Terminal, so I was trying to open a file named

by following command:

open trees.playground

But terminal says:

No application knows how to open trees.playground.

How to make the terminal aware that
can open such file?


Xcode should be the default opening application for .playground files. So following command should work:

open trees.playground

If it still does not, you can just force terminal to open it with Xcode like following:

open -a Xcode trees.playground

To make you understand the above mentioned command, I will break it down:

open [Open something]
-a [With application]
Xcode [Name of desired application]
trees.playground [This file]

In Verbose form, it would mean "Open tree.playground with an application named Xcode".
