Travis GitHub (pre-)release

Apodidae is intended to be the quickest way to search for packages in the Swift ecosystem. By design, Swift pulls dependencies from any git repo, most of which are hosted on GitHub, but distributed amongst many thousands of users. This is fantastic to work with, but what it gains in ease of use, this method definitely lacks in discoverability.

Luckily, GitHub offers a great API which can be utilized to search for possible dependency candidates for your projects. Apodidae searches for repositories written in Swift that also include a package manifest and match your query thus making the search for packages a very swift matter.

tl;dr: Apodidae is a command-line utility that searches for swift packages on GitHub and helps you add these to your Package.swift.


$ brew tap kiliankoe/formulae
$ brew install apodidae

Apodidae conveniently installs as swift-catalog which enables you to just call it as if it were a subcommand on swift itself as swift catalog .... See the usage examples below for more.

You can of course also install apodidae manually.

$ git clone https://github.com/kiliankoe/apodidae
$ cd apodidae
$ swift build -c release -Xswiftc -static-stdlib
$ cp .build/release/swift-catalog /usr/local/bin/swift-catalog


Apodidae exposes a handful of commands. Their use is probably best shown with a few examples. Here's a link to asciinema for a short usage demo recording if you prefer that.

Searching for packages

$ swift catalog search rxswift
- ReactiveX/RxSwift
  Reactive Programming in Swift
- Moya/Moya
  Network abstraction layer written in Swift.
- devxoul/RxViewController
  RxSwift wrapper for UIViewController and NSViewController

Getting info on a package

$ swift catalog info rxswift
ReactiveX/RxSwift 3.6.1
Reactive Programming in Swift

Last versions: 3.6.1, 3.6.0, 3.5.0, 3.4.1, 3.4.0
Branches: develop, master


You can also run swift catalog home rxswift to directly open the homepage to a specific package in your browser. You may know this feature from homebrew.

Adding a package

$ swift catalog add rxswift
Added ReactiveX/RxSwift to your package manifest.
✔ Successfully resolved dependencies.

Apodidae will try to figure out if the project in the current directory uses Swift 3 or 4 and edit your manifest accordingly. After adding it to your manifest apodidae calls out to swift package resolve to resolve your new list of dependencies. If unwanted this can be skipped using the flag --no-resolve.

It's also possible to add a specific version or other requirement. All you have to do is add @requirement to the end of the package. This syntax may feel familiar if you've used npm. The following all work.

$ swift catalog add rxswift@3.6.1
$ swift catalog add rxswift@tag:3.6.1 # same as above
$ swift catalog add rxswift@version:3.6.1 # same as above
$ swift catalog add rxswift@branch:master
$ swift catalog add rxswift@revision:80de962
$ swift catalog add rxswift@commit:80de962 # same as above

For convenience a shorthand syntax for the available commands is also available. You can use s instead of search, i instead of info, h instead of home and a or + instead of add.

Why don't you use PackageCatalog.com, SwiftModules.com, Libraries.io, ...?

These pages are a great idea and are well implemented, but they all use GitHub as a datasource and have to continually refresh their own databases by pulling new data from GitHub periodically. By design, they can't always be 100% up to date and more importantly, they can't automatically know about new packages when they're published. They rely on users manually adding packages or continually searching for new repos themselves.

By having apodidae search on GitHub directly we can circumvent those issues and are still able to find all packages including their metadata.

Why "apodidae"?

The Apodidae or swifts are a family of highly aerial birds. This tool aims to help you find something within that "family".

Why the project? I was missing something akin to npm's search functionality for Swift. So here it is 🙃
