Package Dependencies - Step One


We’ve said several times on this blog that one of the primary goals of the Swift Package Index is to help you make better decisions about the dependencies you include in your Swift projects.

In pursuit of that goal, we just launched a new feature that shows you how many dependencies each of the packages in our index has. 🚀

Even better, it doesn’t just give you the number of top-level dependencies that a package declares in its Package.swift file. Instead, we inspect the Package.resolved file after the build system has done the hard work of dependency resolution.

Package metadata showing that the package being inspected depends on nine other packages.

That said, while this feature adds value and we’re happy to get it launched, this is step one towards where we’d like to be with dependency metadata. Some things to note:

  • The number shown is a count of all dependencies, both package and test dependencies. Test dependencies are far less impactful when evaluating how a package will impact your project, and it’d be great if we could remove those dependencies from the total. Tracked as Issue 1300.
  • It would be great to have a visualisation of the dependency tree for each package. This would be useful both for people browsing packages but also for package authors, allowing them to see the story behind each of their dependencies.
  • We’d also love to get information into the index about how many packages depend on each package. This would be great for curious package authors but also is a strong signal of quality.

However, what we have for now is still a step in the right direction!


About this blog

The Swift Package Index is a search engine and metadata index for Swift packages. Our main goal is to help you make better decisions about the dependencies you include in your apps and projects. If you're new here, the best place to get started is by searching for packages.
