Do you want your prototypes to look as accurate as possible?
One thing that comes up very soon is that you usually do not have installed the fonts that Apple use by default ?♂️.
No worries, you can nail down your prototypes (or apps)….Apple offers the fonts they use, to download for free. You can find them here https://developer.apple…. SF (pro, mono, compact) or New York fonts. Just for you. You only need to install them and voila, available in your favourite editor.
You are welcome!
