Similar library for Julia is Unitful.jl (https://github.com/PainterQubits/Unitful.jl).
Are there any languages that allow units? | May 2023
Julia's Unitful package is one of my favorites. https://github.com/PainterQubits/Unitful.jl

Tangentially related, LaTeX's siunitx package makes typesetting units a joy. Is there similar functionality available in HTML/Markdown ecosystems? https://ctan.org/pkg/siunitx

Julia's Unitful[1] is actively pushing on physical units.

Please put units in names | Mar 2022
Julia supports zero-overhead units:

Not by default, but Julia has various units packages which integrate fairly well with the rest of the ecosystem. Unitful.jl [1] is the most used one I believe and integrates with DifferentialEquations.jl for example. It should also work with many other things, but you might have to patch it up a bit, especially if operations change the units (such as derivatives).

Atlas, a (hopefully) better engineering IDE | May 2021
Julia has the Unitful package [1], which does a decent job. It's quite ergonomic, and Julia's design helps with making existing code/libraries play nicely with Unitful-encoded units/values.

I've seen a few before, and a quick search yielded a bunch for me, right off the bat. By no means exhaustive:

Julia: https://github.com/PainterQubits/Unitful.jl

Python: https://pint.readthedocs.io/en/0.6/

C++: https://github.com/nholthaus/units

etc.

And yes, it has always struck me as strange that date/time/calendar utilities are standard as canonical functionality shipped with language distributions, but units are not.

> It's not JUST google and apple, I'm sure they have enough cash and expertise and will to create enough momentum to attract more domain experts in other areas.

Maybe, but I'm doubtful. Scientific domain experts flock to languages like Python, Julia, Matlab, R, etc. because they're interactive and allow them to quickly iterate on ideas, query data, produce plots, etc. Swift is not much of an interactive language and is not built around that kind of repl driven experience.

> In particular, do you have another example aside from DifferentialEquations.jl ?

Sure, here's a smattering of high quality packages made by and for research scientists:

    https://github.com/mcabbott/TensorCast.jl
    https://github.com/JuliaPhysics/Measurements.jl

There are many many more, these are just the first that came to mind.
