Optionals become timing bugs under concurrency pressure.

Async code will not guarantee main thread execution.

Async code can still block the main actor if heavy work runs there.

Async functions returning off the main actor silently break SwiftUI state updates.

Updating SwiftUI state from a background thread eventually causes rendering glitches.

Async callbacks can race the presentation lifecycle and leave sheets stuck onscreen.

Using .tint as a live reflection of unstable async state creates race conditions users can see and tap through.

List data must mutate on the main thread or diffs can crash later.

Async tests fail when time is implicit instead of controlled.

I got buried in #concurrency and had to stop. 😅
The goal was to avoid using the `nonisolated` keyword in the context where #MainActor is the default isolation, but so far, I haven't found a better solution. 🤔
Here is the first response from the completed request! 🎉
It's taking longer than I thought, but I want to implement strict concurrency responsibly. 🕒🧐
At some points, it works with a project that has default isolation set on #MainActor. This is a default setting for #Xcode26, so I have to follow this rule. 🚀
#BuildInPublic #Swift
So it begins... 🌟
Until now, the package had #MainActor default isolation. This was intentional to gain a clear understanding of where the #Sendable declaration is necessary.
Now, it's time to make this package truly thread-safe! 🚀
#BuildInPublic #SwiftPackage #concurrency
Previous problems with Swift Concurrency, in my opinion, stemmed from originally overlooking this crucial assumption. 💭
Now we can set that Default Actor Isolation will rely on #MainActor. This means our entire app will work on the main thread by default. ✨
2/5
I gave it a quick shot in the morning, and once I passed only local variables to the call, the method stopped running on #MainActor. To be sure, I created an assert for my background handler and called it first thing in all methods. I definitely need to read more on #concurrency.
While moving the last operation into the background, I encountered the strange problem that my ModelActor actually runs on MainActor. 🥲 I'll be reading (again) @mattie's article about ModelActor to understand what's going on tomorrow. I don't have energy for that today. 😆
