The vape ban in Australia is utterly stupid though. All vapes are banned, not just disposables, and guess what's easier to discretely sell to kids from a newsagency.
Doesn't seem to have stopped kids getting their vapes yet I need to import my cannabis vape via the black market.
They're not all banned, you just need a prescription to get one which realistically should've been implemented day 0.
Eventually it'll prove very impactful with the youth, it'll reduce the number of users and make it more cost prohibitive to be so prolific as it is right now.
I wrote an entire, well performing backend in Swift because I could just directly plug in to already existing libraries without having ot provide a whole bunch of "FFI" glue.
All the other languages you suggest is something that Swift excels at while staying performant (also none of those have an IDE like Xcode so idk why you even bring it up). Though for actual systems programming I don't think Rust can be beaten by Swift, simply because of its more explicit (and therefore confronting) nature.
- C/C++ interop is great but if we wanted to use C/C++ libraries why use Swift at all? It's annoying to interop with them even if there is no FFI and still requires a lot of glue code for memory management etc…
- The stdlib (Foundation) is not identical on all platforms even today. This has been a major thorn as releases constantly have discrepancies and subtle bugs that are hard to diagnose and track down. Even Swift 6.1 broke non UTF-8 string encodings by just returning "nil" on Linux and took until Swift 6.2 to be fixed (nearly a year).
- The compile times are awful, with a large Swift codebase it takes us ~10-20 minutes to compile our backend Docker container and thus deployments to dev take that long and it's only going to keep getting longer as Apple seemingly has no interest in making the Swift toolchain much faster and Swift has a fatal flaw in it's design around bi-directional type inference that ensure it can never be compiled fast.
- Talent is impossible to find. Yes lots of people know Swift for iOS apps but nobody knows Swift for server code and a backend dev is a very different skillset than an app dev.
We chose it because it allowed us to share some domain code between our flagship iOS product and the server with a custom built sync engine but as our platform has grown it's just gotten harder and harder to justify keeping Swift on the server which is why we're actively migrating off it.
