The current solution to download the specs every time from S3 still adds 1.5 minutes to every build.
curl https://cocoapods-specs.circleci.com/fetch-cocoapods-repo-from-s3.sh | bash -s cf
Including a recent-ish checkout of the CocoaPods specs repo with the image itself would allow for much faster builds. This is what Travis-CI does, and often allows you to skip
pod repo update entirely if their image is new enough, and when you do, the repo update is generally pretty fast since it’s a somewhat recent checkout.
