Swift Playgrounds: Unable to Resolve Package ‘Graphics’ and ‘unzip’ Executable Not Found Error

When I import a package in Swift Playgrounds on my iPad, I receive the following error:

This package interactions with libgit2, and it don’t have any release in the origin repository, so I find a existing fork which have release.

Playgrounds version: 4.3.1(1727.53)

Is it means that I install a software that supports unzip on iPad?
