A step to retrieve your cache from a S3 bucket using custom keys with fallback. This should be used with the s3-cache-push step to store the cache. If you want to retrieve multiple items, you'll need run this step multiple times. Bucket Access For this step to work you'll need an user in aws with programmatic access to a bucket. The user should have permissions to list, get, and put objects in the bucket. You can set the credentials using the Bitrise Secrets with the keys specified in the inputs or set them directly in the inputs.
