✨Swift 6.2 ✨

SE-0481 is introducing "weak let" to Swift 6.2!

That will allow us to create immutable weak references that can't be reassigned after initialization, but can still become nil when the referenced object is deallocated.

This is a game-changer for Sendable compliance (weak var can't be Sendable, but weak let can!) 🎉

My talk at OneMoreThing 2024 on #UnitTesting #SwiftUI and #SwiftConcurrency was recorded, but has yet to be edited and uploaded.
Last night, I published an edited form of my speaker notes from that talk to my blog.

#SwiftLang

📣 #iOSDev PSA: new #Xcode26 projects default to Main Actor isolation, which can lead to errors with Sendable types ⚠️

Possible Fixes:
1: Change default isolation
2: Mark type as nonisolated
3: Ignore #SwiftConcurrency 🫣

@mattiem has a great post on default isolation: https://www.massicotte.org/default-isolation-swift-6_2

Quite frankly, if I hadn't read your post before, I probably would've taken a lot longer to figure out why the heck the type in question was MainActor isolated to begin with - thanks Matt! 👏
