In this video, we are going to take at Threading and Grand Central Dispatch in Swift.
We will investigate what threads and Queues are as well as the Grand Central Dispatch or CGD, the API for managing your queues. In the process, we will also touch on synchronous vs asyncrhonous code and finish off with an overview of DispatchGroups.

At 4.51 in the video, I mistakenly say that the .default QoS is between .utility and .userInteractive. The slide is accurate though. .default is between .utility and .userInitiated. Sorry about that.

I'm a total newbie and I could follow this. So many other presenters don't put space between their spoken sentences. A learner's brain falls behind fast and never quite catches up. Not here. Great cadence Stewart.

Dear Stewart. When you use groups and when you declare a queue variable as Global, it means the main thread or queue will be notify?

start a discord server. my channel has over 500 members, and around 10-15 active at any given time. We work on projects, and solve leet-code questions. your tutor style would attract a valuable crowd. many would be ingratiated to be under your tutelage. semper fi brother. Contextually, My YT channel averages under 1K views. there is potential in what you are doing and more should know about you. Ps: i would conjecture, given your teaching style and the lack of swifty ds and algo on YT is a benefactor to you market-share positioning (audience) within this cesspool-algo-drive-YT-world we live in.

OMG, the explanation for synchronous vs asynchronous was very bad, although it was technically correct. You explain it in a way that will make new programmers conflate asynch vs synch with serial vs concurrent.

@StewartLynch 2 жыл бұрын

Thanks for taking the time to comment. Perhaps you could point us all to a clearer definition that would make sense in this context. I agree that the concepts often get confused and misrepresented. Again, thanks for any feedback you can give that would provide more clarity. And if there are other aspects of this video that are unclear, please comment as well. It is ot my intention to confuse.

Default case for QoS is shown to be between .userInitiated and.utility but you have said that it is between .userInteractive and .utility. Which one is it?

@StewartLynch 4 жыл бұрын

it is between .UserInitiated and .Utility as it shows, not what I said. I wish there was a way to go back and correct audio on KZfaq without having delete and repost the video. Thanks for catching that.

The ContentViews dogVM var should be @StateObject instead of @ObservedObject. Also there is error in getDogWithSession() at 17:00 in line 59. There is Data(contentsOf:) but we should just use data from completion handler.

@StewartLynch Жыл бұрын

Agreed, but this video was created BEFORE @StateObject was available. @StateObjecet was introduced in iOS 14 and I crated this video while still. using iOS 13
