iOS only recently became a pleasure to develop in with Swift, though the language is still in rapid development (read: constant updates with breaking changes).

iOS only recently became a pleasure to develop in with Swift, though the language is still in rapid development (read: constant updates with breaking changes). Android has and still is an absolute pain; I still don't think I've been able to successfully write an app that looks OK across device screens. Plus the whole fragment vs activity debacle. The whole process feels like a hack. Windows has always been a pleasure to develop in, but that's not where the users are at. If you already do web dev, then learning service workers + local storage won't add much difficulty. Plus, they're excellent tools to add to your toolbelt that your future projects could benefit from. And you'd be encouraging Apple to step up the game with their IE- I mean Safari.
