Peak shittiness requires sacrifice

There’s always an accomplice in crime.

Also, tall order to expect me to run and test a code written only for a shitpost.

Python is by far the clown, especially against JS

Pretty much, with some atomic additions like “you cannot mutate a reference when it is borrowed immutably elsewhere” or “you cannot borrow a reference mutably multiple times”.

I think you don’t know what garbage collection is. Allocations and Deallocations is how the heap works in memory, and is one of the two main structures in it, the stack being the other one. No matter what language you are using, you cannot escape the heap, except if you don’t use a modern multitasking OS. ARC is a type of garbage collection that decides when to free a reference after it is allocated (malloc), by counting how many places refer to it. When it reaches 0, it frees the memory (free). With ARC you don’t know when a reference will be freed on compile time.

In Rust, the compiler makes sure, using the Borrow checker, that there is only one place in your entire program where a reference can be freed, so that it can insert the free call at that place AT COMPILE TIME. That way, when the program runs there is no need for a garbage collection scheme or algorithm to take care of freeing up unused resources in the heap. Maybe you thought the borrow checker runs at compile time, taking care of your references, but that’s not the case, the borrow checker is a static analysis phase in the Rust compiler (rustc). If you want to use a runtime borrow checker, it exists, it’s called RefCell, but it’s not endorsed to use. Plus, when you use RefCell, you also usually use Reference Counting (Rc RefCell)

Don’t get me wrong, Swift is OSS and there are things you can do with it apart from front-end dev, but there are usually better options out there for those other things. For example if I want an HTTP server, I’d choose JS, Kotlin, Rust, etc.

Swift has little to no use outside the apple ecosystem, and even if you are currently using Apple, you have to consider your targets as well. Writing in Swift means your code will only be usable by other Apple users, which is canonically a rather small fraction of technology users. Rust on the other hand is multiplatform and super low level, there’s very few other languages out there that can match the potential of applications of rust code. Thus you will, in time, be introduced to many other technologies as well, like AI/ML, low level programming, web, integrations between languages, IoT, those are only a few of all the possibilities. On the other hand, even if Swift has a much more mature ecosystem, it’s still only good for creating UIs in all things Apple, which is pretty telling; Apple is not willing to put in the time and effort to open it’s language to other fields, because it sees no value in them being the ones providing the tooling for other purposes. They pretty much only want people to code web apps for them, and Swift delivers just fine for that. So if your current purpose is making Apple UIs, you could learn Swift, but be warned that either you’ll either be doing that your whole life or will eventually be forced to change languages again.

Then again, most languages nowadays aren’t that different from each other. I can code in a truckload of languages, not because I actually spent time making something coherent and complete with each one of them, but because I know some underlying concepts that all programming languages follow, like OOP, or functional programming, and whatever those entail. If you learn those you will not be afraid to switch languages on a whim, because you’ll know you can get familiar with any of them within a day.

C# isn’t that difficult to learn. Don’t be overwhelmed by languages or frameworks, they aren’t so different from each other.

You are using two technologies that have a bad of working like shit, together; Ubuntu/snap and docker. You can try podman if you want, or a different distro. Or, at least, install the official docker way.
