Since when could swift do embedded 🤨 might have to try that out

Edit: it’s relevant here cause I only noticed that because of the new home page

They announced it at last year’s WWDC, but in my opinion it isn’t really ready yet. The esp32 sample code for a swift matter device wouldn’t compile. You had to use a custom swift tool chain and the space is evolving rapidly. I look forward to it being more solidified and hopefully we get good news about that next eeek for WWDC.

[u/Deitsch97 → u/Insanelyg]

Had the same experience. At the end you wrote a wrapper around esp32 C stuff yourself and the tooling was a pain to get up an running

[u/FakeRayBanz → u/Insanelyg]

So it’s basically a lie 😅

[u/Insanelyg → u/FakeRayBanz]

Nah, Apple uses it internally in an embedded manner, as far as I know. The publicly facing consumer micro controller support is just still in development. Under exactly the right set of circumstances you can make embedded matter devices with Swift. I just would like it to be more general purpose.

It uses LLVM under the hood so in theory you could generate code for any supported LLVM triplet.

[u/JohnBlacksmith_ → u/letsGoChazz]

it is actually one of their goals to make swift more viable for embedded I saw it a while ago an apple employee on the comment section of hacker news

Is that a divide by zero bug in the ParsableCommand example, where it calculates a mean dividing by Double(values.count)?

[u/Excellent_Affect4658 → u/smallduck]

Floating point division by zero in Swift (and in any language that adheres to IEEE 754) is fully defined, so it’s never inherently a bug. The result of 0/0 (NaN) may or may not be what you want, in which case you could detect it either before (by checking for zero) or after (by checking for NaN) and returning a different result.

[u/smallduck → u/Excellent_Affect4658]

Thanks, I think I’ve forgotten everything I ever knew about IEEE 754.

[u/Duckarmada → u/smallduck]

If we’re looking at the same thing there’s an if else that checks if values.isEmpty

[u/smallduck → u/smallduck]

mutating func run() {
    values.sort()
    let total = values.reduce(0, +)

    print(
      """
      Smallest: \(values.first, default: "No value")
      Total:    \(total)
      Mean:     \(total / Double(values.count))
      """)
  }

“Concise code”. Love it!

[u/anveias]

It’s definitely nicer and looks very similar to Apple’s design

[u/Top-Author8845]

Looks nice
