CocoaCache

Partial CocoaPods Specs cache for the faster CI build.

Background

It takes several minutes updating CocoaPods Specs repository while building a project on a CI server. In order to prevent from updating Specs repository, you have to cache the entire Specs repository located in ~/.coccoapods/repos/master. But this is too large to cache in the CI server. CocoaCache helps to cache specific Pod specs to prevent from updating the Specs repository.

Concepts

Saving Cache (Previous Build)

1. Find Pods from Podfile.lock to cache.
2. Copy the specific Specs from the origin Specs directory to ./Specs.

   $HOME/.cocoapods/repos/master/Specs/7/7/7/ReactorKit -> ./Specs/7/7/7/ReactorKit
   

3. Cache ./Specs to the CI server.

Restoring Cache (Next Build)

1. Restore the ./Spec directory from the CI server.
2. Find Pods from Podfile.lock to restore.
3. Copy the cached Specs back to the origin Specs directory from ./Specs.

   ./Specs/7/7/7/ReactorKit -> $HOME/.cocoapods/repos/master/Specs/7/7/7/ReactorKit
