Jessie Squires published a bunch of great articles on maintaining healthy iOS release cycles:
Here they are:
Comparing release branch strategies
Generally, a release process involves creating a release branch and letting it “soak” for some period of time, usually a week or two. During that time, various tests are performed (automated and/or manual), and anything broken gets fixed. At some point, you decide everything is ready to go and you publish your app or deploy your website. Regarding your release process, one of the primary tasks is to determine where and how those fixes occur.

Using fastlane to increment version numbers in xcconfig files
If you are using fastlane to automate your release process, you might be using the increment_version_number and increment_build_number actions to bump your version and build numbers, respectively. However, if your Xcode project is configured to use xcconfig files, then you are out of luck. Shockingly, fastlane does not seem to support projects that use xcconfig files and there is a surprising dearth of information online about how to make fastlane work with Xcode build configuration files.

Automate merging release branches into your main branch with GitHub Actions
A typical release process for Git workflows involves creating a release branch, performing various tests on that branch, and applying any necessary fixes or changes to that branch. Once stable and ready to release, you create a build from the release branch, create a git tag, and finally merge the release branch changes back into your main branch.

Upgrading Android Attestation: Remote Provisioning
Posted by Max Bires, Software Engineer
Attestation as a feature has been mandated since Android 8.0. As releases have come and gone, it has increasingly become more and more central to trust for a variety of features and services such as SafetyNet, Identity Credential, Digital Car Key, and a variety of third-party libraries. In light of this, it is time we revisited our attestation infrastructure to tighten up the security of our trust chain and increase the recoverability of device trust in the event of known vulnerabilities.

How a single Android developer improved Lyft’s Drivers app startup time by 21% in one month
Posted by Mauricio Vergara, Product Marketing Manager, with contributions by Thousand Ant.
Lyft is singularly committed to app excellence. As a rideshare company — providing a vital, time-sensitive service to tens of millions of riders and hundreds of thousands of drivers — they have to be. At that scale, every slowdown, frozen frame, or crash of their app can waste thousands of users’ time. Even a minor hiccup can mean a flood of people riding with (or driving for) the competition. Luckily, Lyft’s development team keeps a close eye on their app’s performance. That’s how they first noticed a slowdown in the startup time of their drivers’ Android app.

Google Maps has always been one of my favorite apps. The two-layer design makes it so convenient for users to browse the map and find details at the same time. The expanding feature on the front layer makes the information flow so easily and the dragging gesture makes users feel like a magician themselves. :)
