What do they mean by native? That they are using macOS dev frameworks supplied by Apple, instead of a framework like Electron? If that is the case, how are they planning to have a Windows version?
Yes, we build it natively. There are tons of native applications: sublimes, Dropbox, chromes etc... and many ways to cross-platform. I don't want to spend 2GB for every electrons app (slack, vscode, database app...) so I build TablePlus natively.
Basically, I split the project into 2 pieces. Logic and Interface. The logic can cross-platform because it is pure C/C++.
Chrome has a custom GUI framework of their own, and it does not look native in many cases (alerts, for example). Dropbox on Desktop is written in Python and uses PyQt (Qt itself is in C++ and looks fine on all platforms).
