What is the Sendable protocol in Swift? | Swift Concurrency #11

The Sendable protocol is actually a super-simple protocol that let's us tell the compiler whether or not an object is safe to send into an asynchronous context. For our purposes, this will mean whether or not we can safely send an object into an Actor!

bro you are amazing

Edit: Also sendable acts as a guard for future safery thread checks, is someone ads a var to a sendable without being aware its being used in asyc sendable will alert them.

Trying to think of a case that a final class would be needed where a struct or actor couldn’t fit the bill. In the unchecked sendable case shown in the video all we are really doing making an understudy, weak actor, aka an novice implementation of thread safe class? What am I missing?

hey vro ...how to make Core Data Entities conforming to Sendable??

[alexvaiman]

as i said before about mutating.. you must be careful.
struct MyStruct: Sendable {
var title: String

mutating func changeTitle(newTitle: String) {
title = newTitle
}

func unsafe( t: inout MyStruct) {
t.changeTitle(newTitle: "new title")
}

func test() {
var t = MyStruct(title: "hello")
unsafe(t: &t)
print(t.title)
}
}
