? How to improve iOS build times with modularization

@xiangerxiansen : With the iteration of the business, the complexity of the project code is getting higher and higher. If our application cannot be well structured, it will seriously slow down the compilation speed and affect the development experience. This article introduces the “modularity” approach (which many big manufacturers do), and uses horizontal dependencies (instead of vertical dependencies) between modules to solve this problem.

? Moving “The Swift Programming Language” book to open source

@Smalfly : Swift-DocC is a documentation compiler launched by Apple in 2021, which can generate documentation by compiling comments in source code. Recently, Apple open sourced the source code of Swift official documentation on Github, claiming that Swift-DocC will be used to build documentation based on this repository in the future. Apple expects to work with the open source community to improve Swift-DocC, and expects developers to contribute to official documentation.

To learn more about Swift-DocC, please refer to the internal reference article [ WWDC22 110368/110369 ] New Features of Swift-DocC .
