One of our main goals was to minimize code complexity and eliminate redundancies. or. We also used quite a few of the OS libraries, including the JSON processing library, rather than building and storing our own libraries in the codebase. Editing a few sections of code wasn’t going to be enough. With that principle in mind, we began looking at the right way to make our iOS app significantly smaller. Forgot account? With MSYS, it’s easier to track performance, spot regressions, and fix bugs across all these features at once. And yet, for the people using the app, it won’t look or feel much different.

Concerned with overall holistic architecture of Twitter. But this is just the beginning. Create an account or log into Facebook. That and the large amount of code made the app’s cold start much slower, especially on older devices — and with nine different tabs, it was trickier for the people using it to navigate.

Compared with the previous iOS version, this new Messenger is twice as fast to start and is one-fourth the size. The Settings page appears. As Mark pointed out, at the high level everything is a node or edge. We looked at how we would build a messaging app today if we were starting from scratch. This reduced not only size, by avoiding the need to cache/load large custom-built frameworks, but also complexity. The native frameworks don’t have to be translated into sub-frameworks. This architecture has the same 2 layers - backend code and DB/other services. Turn on Post Notification _____ Tonglu..., China • Capsule Hotel and Bookstore design by @atelier_taoc • The exterior renovation is an extension as well as a reflection on the reorganization of the interior spaces.

After exploring our options, we decided we needed to look past the interface and dig into the infrastructure of the app itself. When we started thinking about this new version, Messenger’s core codebase had grown to more than 1.7 million lines of code. But we went even further.
