Then opened it in Sketch. I was able to take an SVG and paste it into one of the spots in the grid, but am missing how I am supposed to make thicker versions. So do I have to basically figure out how to thin out the lines? in svg? I might as well just write the code to animate this? Seems ridiculous. I thought the template would have one symbol that you put some path info into and then it replaces the grid of symbols.
Totally don't understand how the team found the time to produce a WWDC session but not a simple guide to doing this, I don't know, with an example.. ?
