fastlane/fastlane#13833

This script may be useful to you if you use fastlane for iOS CI builds and your Apple developer portal account uses 2-factor authentication. There is reason to suppose that Apple may not be persisting these sessions for as long as they used to, and hence you might find yourself needing to update FASTLANE_SESSION for your CI projects more often than usual.

This script is a way to mostly automate the process of updating FASTLANE_SESSION if you use CircleCI as your CI provider. It expects to find your Apple username in env as FASTLANE_USER, your Apple password as FASTLANE_PASSWORD, and your CircleCI API token as CIRCLE_API_TOKEN. It then executes fastlane spaceauth and waits for you to put in your 2FA code. From there, it parses out the session data and then uses the CircleCI API to populate the specified projects with the newly updated FASTLANE_SESSION. You'll

Installing Fish shell on MacOS (Intel and M1) using brew

Fish is a smart and user-friendly command line (like bash or zsh). This is how you can instal Fish on MacOS and make your default shell.

Note that you need the https://brew.sh/ package manager installed on your machine.

Whole Module Compilation Optimizations: Why these terms are sometimes misleading

When you look up how to compile swift faster for debug builds, people very earnestly give advice that seems contradictory: you should "try using the whole module optimization flag," and also "never use whole module optimization for debugging". [^1]

This is confusing because some of us are using these two general words:

compilation: "turning text into an executable program"
