Static linking will do that. Imagine you have 400mb of binary objects your app depends on. Libraries your company uses for app analytics, SSO, 2FA, Corporate service bus api, etc. You statically link all those for your 50mb Swift UI app and bam, you’re in the 700mb range.
That's a lot of code, though. I can't imagine common libraries so big. The Linux kernel is less than 100mb.
The use of Go will definitely do that, as it prefers to statically link everything.

If we had an entire POSIX OS built with Go, then we would be back to statically-linked UNIX prior to BSD.
