For what it's worth, economically for an individual, it's sort of the reverse in my experience. I feel like I snuck into Google in ~2016 because pure-iOS is so rare. I only had 1 out of 7 interviewers who worked on iOS, 2 who had tangential brief experience, 4 who had never used it. Also, Swift was new, so the people who <i>did</i> know iOS couldn't really speak to it when I used it to write code.<p>If I'm launching a product, I'm doing Flutter. To me, it's Swift but with no rough edges. Most importantly for a product, it lets me maximize leverage and get cross-platform. The performance is really astonishing compared to my days with React Native, it's native in that it's not being JIT'd.<p>But if I'm happy with a nice gig / set of consulting clients doing iOS, that's great, probably can do that until the end of time. I think we're seeing the first wave of startups doing Flutter to maximize engineering leverage, but long-term, it's too divisive to have a singular Flutter codebase for most large businesses. They'll specialize.
