While the overall point is valid, this isn’t strictly true. A Swift string is frequently backed by a contiguous UTC8 buffer terminated with a \0, so passing to C is just a matter of passing the pointer and requires no copies.

Yes, this is the correct behavior. If Alice and Bob disagree about whether or not that row should be in the table you aren't going to fix it with math. More often than not, the expected outcome will be obvious (i.e. spelling correction

The best UX resolution to this kind of issue I have seen is to display “This table cell was added by Bob concurrently to Alice removing its row. How would you like to proceed: recover the row or ignore the change?”

For the record, you do have fairly fine grained control over what updates when with SwiftUI. The issue is that this isn’t obvious to new developers, nor is it easy to understand what tools to use to fix issues once you understand what is ha

This could be taken to support my point. There is a MASSIVE amount of literature on the internet about how to do this, and it's reasonably straightforward to see what is happening with the DOM when you use these frameworks. Likewise, a

I’m happy this worked for you. This in itself is an interesting anecdote about documentation quality. I knew this API existed but forgot the exact API and searches for “caching SwiftUI rasterized view” and similar queries did not return thi

Other commenters have pointed to SwiftUI being declarative as a big part of this problem, but I take a more nuanced view: the problem is actually that SwiftUI is a complexity-hiding abstraction. Specifically it hides the complexity of when

I can’t speak for the author, but I’ve had a similar feeling. Where (safe) Rust’s core principle is memory safety at all costs, I feel that Swift takes a more nuanced approach, prioritizing making good programming patterns easier while stil

If M2 Pro is similar to M1 Pro (two M1s duct-taped together with very fancy duct tape), this is interesting because usually chips need to be significantly reworked for a newer process and this implies an M2 core complex will be printable

The one thing that has come of this is that products that do this have 0.5% less friction (they can auto-update quicker), achieved this faster and with less engineering effort (no need for a clever workaround, just use the biggest hammer),

I tend to agree with much of the criticism of SwiftUI, namely that it and the underlying mechanism (result builders) is over-indexed on the UI-for-iPhone-apps use case. But I think Swift's greatest strength is what I mentioned in the p

The move function is not move semantics (though the latter is being discussed by the community). The main purpose of the move function is to explicitly document where performance sensitive code depends on a specific type of compiler optimiz
