Concurrency using Actors | Swift 5.5 | Async/Await | Data Race 

You have great didactic abilities … bravo from 🇨🇭

Why writing Task in DispatchQueue ? Also 5:31 why we want to halt the main. thread via using `sync` instead of `async` , is it just to return value?

Awesome video. Thanks for sharing your knowledge. Helps a lot

Awesome awesome explanation brother 🤩🤩. Thank you so much for your all videos 😍

Thank you for nice content.

Thank you for awesome video !!!

Actor concept is Nice , it's really interesting, compare to existing techniques.

Hey, thanks so much! Why are the queues at the end still needed? Or if they aren't needed, why are you still using them?

Very well explained. Keep up the good work.

well done very nice explanation 👍

Learnt something new today. Thank you. What I am more curious about is how the actor is working internally?

Thanks for the nice content

Thanks Palav

Hey pallev, Thanks for the video. Have one question why you used sync on both operations with barrier.I think same could be achieved without using barrier on sync operation (as they already in sync)or async operation with barrier?

Very nice explanation.

Very nice sir. thanks

Interesting trade off. The barrier was neat in the old Flight class. Now the burden to make it properly called, the caller are forced to call with async await.

Superb keep posting💪

superbb

Great Job 👏

Hey pallev, Thanks for this great video. now I have a clear concept of Actor. I would really appreciate if you can come up with one video of Closures. thanks

Great tutorial. I observed that even when I did not create add keyword "MainActor" and just called the updateLabel method from my Task block, I did NOT get a crash and the setting up the break point inside updateLabel showed that it was on main thread. How is that possible?

Nice explanation 👍

Impressive ....once again.👏👏👏

Hi Pallav, Great fan of yours. In a couple of interviews, I faced this question. "How do you convert struct to a class? or atleast give some functionalities of class to struct." I searched a lot through web but couldn't find any answer. Could you please help me with this.

I learnt the latest topic. Thanks for sharing.

thanks for the video keep up the good work :)

And chance this is usable also for communication between realtime audio thread and main thread ? I mean if you are trying to communicated between realtime audio thread and main thread there are some forbidden things like using of MUTEX - so any chance all this Actors aren’t using MUTEX ?

Thank you for sharing the valuable information

🎉🎉🎉🎉❤

👍

Thanks for this lesson)))

When should we use weak and unowned in swift?

Sorry dear i would like to correct you... why you are blocking the queue using sync operation, you must use barrier flag on concurrent queue with async operation always.

Hi Pallav, Thanks for the video. I tried with same approach but surprisingly it worked if I used the 2 queue like in your video but whenever I tried with 3 queue it is not working. I am sharing the code snippet for the same. Share your thought on it. actor Flight { var availableSeats = ["1A", "2B", "3C"] func bookSeat() -> String { let bookedSeat = availableSeats.first ?? "" availableSeats.removeFirst() return bookedSeat } func getAvailableSeats() -> [String] { availableSeats } } class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let flight = Flight() let queue1 = DispatchQueue(label: "queue1") let queue2 = DispatchQueue(label: "queue2") let queue3 = DispatchQueue(label: "queue3") queue1.async { Task { let availableSeats = await flight.getAvailableSeats() print("Available seats \(availableSeats)") } } queue2.async { Task { let bookedSeat = await flight.bookSeat() print("Booked seat \(bookedSeat)") } } queue3.async { Task { let availableSeats = await flight.getAvailableSeats() print("Available seats after booking \(availableSeats)") } } } }
