Typography is impossible
Marcin Wichary

This is awesome. Similar sentiment when it comes to aligning text and messing with the parameters. By the way for iOS, it is a good practice to use the system font with the built in text styles. https://developer.apple.com/ios/human-interface-guidelines/visual-design/typography/ With Dynamic Type, tracking and leading are “AUTOMATICALLY” adjusted for every font size. And also accessibility features are enabled by default. If you are going to use a bespoke brand font, make sure you plan for that.
