Will be interesting to see how Xcode handles the new stuff as far as defaults for new projects / migration aids for existing ones.

massicotte.org•4 days ago

I *think* it will follow the compiler conventions just as it did for 6.0.

My understanding is there will be a migration tool for nonisolated+async semantic change, so that’s definitely interesting!

glhaynes.bsky.social•4 days ago

I believe new Xcode projects (maybe only app projects?) still default to Swift 5 language mode today. Maybe we’ll see that change if the new stuff really does smooth off the sharp edges enough?

Cool about the migration tool, looking forward to using that.

I have no insider information but I’m just going to say that the language mode default will not change.

Most of the features that do make things easier are already defined as opt-in. Those could potentially be on, but I doubt it…

Interesting! Well, one thing Apple has usually been pretty good at is transitions so imma trust that they’ll figure this one out over time.

So, when should I start learning Swift Concurrency? 😂

massicotte.org•4 days ago

hey wait you are using concurrency! I think you know it a lot better than you might think.

alpennec.com•4 days ago

Ah ah yeah it was a bad joke. But it seems I’ll have learnt too much in the last years now it gets simplified.

massicotte.org•4 days ago

what's truly interesting about the changes is all your learning is still completely valid with just one exception (the whole nonisolated+async thing).

SE-0461, SE-0466 & SE-0470?

massicotte.org•4 days ago

You got it! And 0461 is the only one that actually meaningfully changes how things work.

Suppose I’ve already come to terms with it.

Do I have to rewrite things.

Again?

massicotte.org•4 days ago

You do not!! But it’s possible you can use these things to make the stuff you have written simpler.

Oh wow, this thread got me reading SE-0461. That's really going to fix a lot of the pain.

massicotte.org•4 days ago

Yeah that’s the big one
