I'm loving SwiftUI right now and can't wait for it to become more mature. This year's changes were a great step in that direction.

I love how you can come and say I don't know about this . I can never do that in public And also for helping me with the "SwiftUI has no place to do the network call" (You can use the onAppear solution but it isn't what you always want to do) The concept you explained was beautifully done

Woo new video! Hey Brian, you think you will ever make a course with Unit Testing? I've been interviewing for entry level iOS positions and so many companies want you to have that experience. I've been reading up on it, but still have trouble creating/applying unit tests to my own projects. They're really aren't a lot of youtubers applying unit tests to their projects.

Hey Brain, I just wanted to suggest that you make a video showing the sequence of the videos you have made on YT also tell us the sequence in which a new student should start watching the videos . I wanted to see the videos right from the beginning and since there are so many of them its kindof confusing .

Great tutorial. Xcode complained about setting the published array of Applications off the main thread.. so I changed the JSON request to be more "SwiftUI/Combine ish" by making the request: URLSession.shared.dataTaskPublisher(for: url) .map(\.data) .decode(type: RSS.self, decoder: JSONDecoder()) .map { feed -> [Application] in return feed.feed.results } .replaceError(with: []) .receive(on: DispatchQueue.main) .assign(to: \.apps, on: self) .store(in: &cancellables)

Key takeaways from the video: 1.How and where to make a network call in the new SwiftUI Lifecycle based App 2. Why you should have a viewmodel in your app 3. Using KingFisher in your app (I'd really like to see the animation stuff when the image loads to be added by the dev for swiftui) 4. Serializing JSON selectively in a SwiftUI app and using the Codable, Hashable protocols
@jwenaposse305 3 жыл бұрын
Love this video. Is it also possible to use a struct and @State for your data model array? I know that classes should be used for more complex non-primitive data.. but what if we would be dealing with an array of ints or bools, also fetched remotely from a server.. I am trying to understand when to use the @observableObject / class route versus @State / struct. Thank you for any insight in this matter.

@Lets Build That App Are you gonna be making some videos on how to build clone apps in SwiftUI, like Uber and IG, for example? I'm in the early stages of learning iOS development and after hearing your comments near the end of your "Swift Grid Columns With JSON" video I have made up my mind that, contrary to what I've been told repeatedly, learning UIKit and storyboards would be a waste of my time. By the way... great videos Sir!

Hey Brain , I hope you are doing well . I hope you can do a demo in tableview on how : 1- How to populate diff UIs in diff sections within diff cells only using 1 UITableViewCell let us say for example you want to show in - (0,0) : ImageView , labels - (1,0) : another label - (1,1) : UIBottun - (1,2) : another label - (1,3) : another imageView - (2,0) : UItextfield . and you get what I mean using an enum or a viewModel to make the tableView scalable and robust . not sure if this could be solved by using only 1 UITableViewCell . and Thank you .

@Brian, I'm very interested on CI/CD and testing, Do you have any course for this? if it is not the case, do you have any plans for this? I wouldn't have any problem with paying a course of this topic taught by you.

Yeah it takes an entirely different mindset to be really good at CI CD. Unfortunately I haven’t had the time to go in-depth with these topics to the level where I’m comfortable teaching it. I can setup jobs and run automated testing with many build machines but not sure how to teach this.
