I think SWR is common on the web, but is it not so on mobile?

Hi, thanks for your content which I've been following for a while and which has greatly helped me evolve on React Native in general. Could you teach us how to test our React Native code with Jest or something else for Typescript without Expo? It would be really interesting to develop our know-how. Thank you very much for everything you do 👍
