E.g. the "gearshape" or "gear" symbol, they are very close to the title, whereas the "function" symbol is far away. It only seems to be a few pixels, but both next to each other look pretty bad. I would upload a picture, but I don't see a way to do that here.

First of all, thank you very much. I came across this StackOverflow question yesterday as well but thought I did something wrong and creating my own image just didn't feel right, but if that's the solution. Still, I don't understand why the imageInsets do not work on UIImages that are initialized with an SFSymbol but do work when I use an image which is in an Assets folder.

Sure and thanks in advance.
