Ello iOS App
Environment Variables
We use the dotenv
gem to access application secrets in the terminal, and cocoapods-keys
to store them in the app.

Universal Links
Starting with iOS 9 Apple added support for Universal Links. The previous link does a good job explaining the concept. Generating the apple-app-site-association
file that is needed on the server is not well explained.

Pinning certificates
We use pinned certificates to avoid man-in-the-middle SSL attacks. We use a rolling "primary + backup" pair of certificates, so if the primary expires or needs to be pulled, the backup is easy to swap in. Every now and then the primary / backup need to be rotated.
