Ello iOS App
Open source, but not open API
Our API requires an application key and secret, which are currently being kept private. You can browse the source, and you can compile it, but you won't be able to run it against our API. Sorry, but we don't have the resources to support this kind of open access. We have always planned to offer 3rd party access, so hopefully this will change soon!
Environment Variables
We use the dotenv gem to access application secrets in the terminal, and cocoapods-keys to store them in the app. Add the following values to your .env.
ELLO_STAFF: set this in your bash/zsh startup script to access private cocoapods (you must have access to the private repos).GITHUB_API_TOKEN: used for generating release notes during distributionINVITE_FRIENDS_SALT: used for generating the salt for sending emails to the APIPROD_CLIENT_KEY: the key or id used for oauthPROD_CLIENT_SECRET: the secret used for oauthPROD_DOMAIN: the domain for the API to hitNINJA_CLIENT_KEY: the key or id used for oauthNINJA_CLIENT_SECRET: the secret used for oauthNINJA_DOMAIN: the domain for the API to hitSTAGE1_CLIENT_KEY: the key or id used for oauthSTAGE1_CLIENT_SECRET: the secret used for oauthSTAGE1_DOMAIN: the domain for the API to hitSTAGE2_CLIENT_KEY: the key or id used for oauthSTAGE2_CLIENT_SECRET: the secret used for oauthSTAGE2_DOMAIN: the domain for the API to hitSTAGING_SEGMENT_KEY: used for sending data to segment
Setup
Once you have client credentials, compile them into cocoapods-keys by running:
rake generate:keys

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.

APNS certificates
See also http://docs.aws.amazon.com/sns/latest/dg/mobile-push-apns.html
Create the certs in Apple's developer portal in the usual way (using the 1Password APNS password as the cert keyphrase), and download the .cer file (two of them, actually, one for co.ello.Ello, one for co.ello.ElloDev). Install that file into your keychain, then export the private key (in.p12 format, with no password).
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.
Cutting a new release
Merge all new changes into master, checkout a new branch release/x.x.x. Change version number in Ello and Share Extension targets. Create the archive using the Ello scheme (not ElloDev). Using Ello will update the build numbers in both plists. Commit version and build number changes. Upload archive to TestFlight. After QA changes are often required. Continue making changes, merging them into master. Then rebase the release branch onto master and repeate until a release candidate is submitted to Apple for review. Once the release is approved and live in the store you git tag x.x.x and merge the release branch into master. Following these conventions will allow github to automatically mark the release as an official release.
Sometimes you may need to increase the build number without making any changes to the code. iTunesConnect requires unique build numbers which in our case, are based off the number of commits. Any easy way to do that is git commit --allow-empty -m "bumping build number".
