A great post duet from Craig Hockenberry that flew by on Mastodon and clarified something for me:

[For] the extra work to create a custom SF Symbol, our experience is 8-10 hours per symbol. This is also an expert level task: lots of knowledge on how SVG control points work and how to maintain compatibility across different sizes and weights.

If you’re paying a designer to do this, the cost will be somewhere in the $1000-2000 range. For Apple this is an easy cost to absorb, for smaller developers it’s a big “nope”.

And, of course in the Mac menubar (and now iPadOS) you need a lot of them.

Another subtle example of how out of touch Apple Design is with day-to-day development.

So not only is the overiconification of menus in macOS and iPadOS a bad idea, but it’s also expensive. You could make an argument that it would push people into reusing SF Symbols – ergo “consistency” – but that would land better if we haven’t already seen even Apple is struggling with that on their own (previously, previously).
