This is a really handy tool for working with and even learning how to use attributed strings. I’ve been using it to improve the look of my own iOS app (Gym Log+) in certain key places where I want nicely formatted text. The live code generation works great and saves me time since I can easily experiment with different font sizes, styles, etc. without constantly re-running my app. One recommendation would be to have an option to store each substring in the newline-separated text into its own variable to make it easier to manually edit the generated code after copying into a project if necessary. Does what it says it’ll do, and no crashes—great job!
