I re-wrote one of my apps in Swift. I don't know Swift. It's been fun. When it gets stuck I look at the code; I have it teach me via analogy to the e.g. mobx/react concepts I do know. In some cases I've improved the LLMs code after learning how something works. In others I work it more like an informed PM - ok the sidebar opening is slow but... its about 10x faster in my electron version. How is the sidebar "mounted" or rendered? I dump tricks I know from web dev and ask how analogues; sometimes that breaks its anti-patterns. Other times I throw constraints I don't know much about - "This is a native version, can we aim to make it 3x faster to start-up? How".

Personally I was surprised how quickly I surpassed my original code, feature wise. Will it stand the test of time? Too early to tell - need to see if I'm still using the native version of the app in a year. But its been more fun and informative - and fast - than I'd expected.
