We've seen Apple iterate *a lot* over the years, and a lot of the core issues with Swift (boilerplate, type system complexity) have been addressed incrementally. 2026 is a long way off, but if they\u2019ve truly embraced some of the more modern language design principles \u2013 like better support for generics and maybe even some kind of robust macro system \u2013 then it could be genuinely compelling for cross-platform development beyond just iOS/macOS. Still, I'm not holding my breath.\n\n**Comment 2:**\n\n> The biggest hurdle for Swift\u2019s wider adoption is still Apple\u2019s walled garden.
