This repository contains the .podspec files for pods that are used internally by Automattic, to develop our iOS and macOS apps.
To use any of the Pods published in this internal spec repository, you will need to add this repository as a source at the top of your Podfile.
Note that since you will likely want to still also use public pods (published by the CocoaPods community on trunk / the CDN) in addition to Automattic's pods, you will need to add CocoaPods's CDN as a source explicitly too.
source 'https://github.com/wordpress-mobile/cocoapods-specs.git'
source 'https://cdn.cocoapods.org/'CocoaPods implicitly uses the CDN as a source if there is no explicit source declaration at all in your Podfile; but as soon as you add at least one source, you need to explicitly declare all the sources you want to use, including the CDN.
For security reasons, when adding the source declarations to your Podfile, you should add Automattic's spec repo first, and the CDN last.
This is because when CocoaPods looks up pods, it searches the various sources in the order they are declared. That means that if someone publishes a malicious pod in the CDN but with the same name as one of Automattic's pod, and you declared the CDN earlier in your source declarations, that malicious pod would take precedence over the one from Automattic. While declaring Automattic's spec repo first and the CDN later will give Automattic's source precedence and avoid any name spoofing attack.
