The backends (FLTK/Gocoa) are using CGo, which currently does not support cross-compiling as far as I know.

So you still need to have a build pipeline with multiple operating systems, signing/notarization tools, etc. :(

You can cross-compile Cgo, you "just" need a C compiler and linker that works for the target platform. osxcross, xgo have some or maybe you can set CC=zig cc.

For macOS you need signing/notarization tools either when building natively or when cross-compiling, it's not any different. `rcodesign` has made this process much easier in recent years.

+1 for `CC=zig cc`. Feels like magic

Too bad.

I swear half the electron apps use it for ease of Xplatform build.

I’d love something like this for giving my CLIs UIs.

That'd be amazing not only for go apps but for software built on other languages as well. I'd pay for a good, straightforward build packing + crash reporting + autoupdater solution for my apps.
