SwiftUI is a new declarative framework to build user interfaces for apps across all of Apple’s platforms including iOS and the new iPadOS.
I’m super excited about Swift UI because it addresses the biggest concern I had with teaching programmatic UIs to beginners: that they would get lost and get discouraged.
SwiftUI is both intuitive and easy to grasp and it offers the maintainability and flexibility of a UI built with code. I’m going to start adopting it into my beginner material and I think you guys are going to really like it!

No I have not yet. I’m actually going through your courses and my question is: shoutI stop and start studying Swift UI or keep going through the courses?

@CodeWithChris 5 жыл бұрын

If your focus is to make an app for iPhone only, the course is still 100% valid because Swift and SwiftUI are 2 different things. Swift will still be used to write the brain of the app. Now SwiftUI is the new kid on the block that allows you to skip the storyboard to make your app cross platform from iPhone to iPad and to Mac! I don't think Apple introduced Swift 5.x to trash it 3 months later with SwiftUI. Everything you still learn now and tomorrow will still be useful ! @AdrienVillez

Later, when it’s officially released, I can reclaim the space used when I install Catalina over Mojave and Xcode 11 over top of Xcode 10. Hope that made sense mate. Thanks for these tutorials in SwiftUI Chris, the more I work with it the more I’m liking it. Definitely a game changer..👍👍👍

Hi Chris, I wanted to try SwiftUI as soon as Xcode11 came out. Only it didn't work without OSCatalina, I couldn't wait to try SwiftUI so i installed my first beta on my MBP. I made OSCatalina run on a USB-stick, you never know. It runs good but I can't run Xcode files from my desktop. My files have to be put in a different folder. That took me a while to find out, thanks to the mighty internet. I started learning Swift from Swift 3 so I am not new but definitely not a pro. SwiftUI puts me back a few steps. Your tutorials help me a lot, keep it up.

Thanks for all the videos you make. They are fantastic. If you wanted to let the user swipe between each child view (the location view in this case) how would you do that? Going from the list to the detail is great and well supported but it seems like there would be lots of use cases where the user would like to easily go to the next detail/child view without having to go back to the list.

"Hello, you can try adding gestures and save ""previous"" selection so you can trigger the navigation from there, however it should not probably work if you just opened the app and did not make a selection yet and actually navigationview already implements a ""swipe"" feature already, try running it on your phone and try swiping after a selection it should work - Francis"

On start of your application, if the user is logged in - load some view called HomeView, if the user is not logged in load LoginView, the user should be able to logout at any point, which should again load the LoginView. How would you tackle that in SwiftUI? Note that HomeView is not the initial view, so if you are logged in you actually skip 2 views, InitialView and LoginView and go straight to HomeView. How would you tackle this if the user just logged in and logouts, or logged in, closed the application then started it again and logged out?

Another difficult one. Here's a beginners question for you. Does SwiftUI use more code than UIKit (with storyboard) so that one page of code looks neater?

@glenreidy 4 жыл бұрын

Gave up just over half way. Too much. Not because of the video but the content in general. I also tried the apple tutorial. It's not making any sense to me yet. I think I'll try something a little easier or I'll just burn out and loose interest in SwiftUI.

Hello, since. SwiftUI relies heavily in coding, then yes it would require more info how to make your app/UI look for cleaner and better, but for making simple design UI then using the default values should be fine for practice - Francis

1:03 you should add this to the card (i) so we can select it. Currently only 'SwiftUI Basics for Beginners (2019)' is there. Actually I do not see 'SwiftUI Full Tutorial' in your video list. Also, the SwiftUI Basics for Beginners (2019) is xCode 11. I hope all your new projects are not predicated on upgrading to a beta app and os?

SwiftUI has to be recorded with Xcode 11. Now Xcode 11 is gonna come out in less than 3 months so, it's nice to already have recorded with Xcode 11. Regarding the regular Swift and UIKit, it doesn't make a difference. @AdrienVillez

I’ve seen many tutorials where the NavigationBarTitle is appended one level below the NavigationView - for example in the LandmarkList it would get appended on the closing curly bracket of the List - why is that?

@CodeWithChris 3 жыл бұрын

Hello, becuase the navigationBarTitle is an attribute of the NavigationView, so it should be inside (or appended after the bracket). think of it as an attribute of the class like lets say the class is Person and it has a "name" attribute, so to access and set the attribute you should do Person.name. Same logic goes for this but its just a bit longer with more content - Francis

I feel like apple decided to enter the home by climbing all the the trees and through window, ignoring perfectly working, comfortable door( SwiftUi is totally a mess to me, sure we can memorize a hundred ways to get what we want, but why? when we learn something, we forget something. The old way worked, it did have a preview too, even if it was not live it sure does not make this better for me, this is not like swift at all. Why would they do something like this when they made swift in the first place. So far - I really hope SwiftUi will be only an alternative. this is just a new way to fill our memory with something (

Now, I haven't been coding for a loooong time and I'm focused more on video editing than Xcode so, I can't really say it's hard or complicated since I never put my hands on...
