Threads and Grand Central Dispatch in Swift

День тому

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.

@@StewartLynch and your right, nobdoy is forcing me to watch. but my mom is addicted to meth, and i dont have a father., i have to take care of my little brother and ive been coding since 14, so i do kiind of have to watch your videos! thanks for being a jerk tho!

@StewartLynch 3 роки тому

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 really don't think anyone can explain it better then you did, Great job.

you turned the light on for me with respect to threading... thank you.

By far, the best Swift programming content on UKposts. Thanks for this excellent explanation.

Thanks for your comment

@manwithllama 2 роки тому

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.

@StewartLynch 2 роки тому

Thanks. I was a school teacher in another life so I think I understand. I taught math and learned that I had to pause to let things sink in.

@victorsebastian732 3 роки тому

Wonderful explanation. My long time doubts about GCD have been clarified. Thank you!!

This is one of finest explanations out there for Queues. Quick question, what is an operation queue and where does it fall in what you have just shown in this video.

Simple and concise explanation, thanks a lot! Can you pls clarify what is task, what is resume, what is NSoperation queue that you used in demo?

@aldairraulcosetitocoral5659 3 роки тому

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?

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 3 роки тому

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 UKposts without having delete and repost the video. Thanks for catching that.

@alimehmood8654 3 роки тому

Stewart Lynch thanks. You can try putting this correction in a pinned post.

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.

@followerOfJesus723 2 роки тому

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 роки тому

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.

@maqusss Рік тому

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 Рік тому

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
