Custom SF Symbols for iOS App

I recently designed these custom SF Symbols for my Raw Beat iOS app: https://apple.co/4fRfJfZ . Thanks to the power of SF Symbols I got these awesome animations “for free”.

I thought I'd write down the lessons I learned and share my insights in this article: https://medium.com/@davidkatsman/how-to-create-custom-sf-symbols-d0e0abdb4972

I’m curious to know how many designers had similar experiences with creating custom SF Symbols for Apple platforms.
