1. Swift tends to be about on par with Java in the language shootout. 2. Java tends to at least around 2x slower than C. 3. For my book[1], I wrote a chapter on Swift and did quite a bit of benchmarking. Just how bad Swift was actually surprised me, and I wasn't expecting it to be particularly good. 4. Case study: https://blog.metaobject.com/2020/04/somewhat-less-lethargic-... Even the worst Objective-C implementation I could think of (really comically bad) was 3.8x the speed of Swift's compiler-supported super-duper-sophisticated implementation. With a bit of work I took that to around 20x. [1] https://www.amazon.com/gp/product/0321842847/ref=as_li_tl?ie... |
