Swift and the Reduced Binary Size
Previously I wrote about a command line tool architecture. There was a program to add events to macOS Calendar. After all, a final binary file size was 10 MB in Debug build configuration and 6 MB in Release.
A great approach for teams with more than one developer is to enforce code style usage. In my team, robots helps make the code in the project conforming. For Objective-C projects we always had clang-format and OCLint. For Swift projects other guides and other tools.
