Data Flow in a SwiftUI App 

I started watching your videos 6 years ago when I was in high school to learn coding. Now, I've graduated college, working as a software engineer and am still learning a ton from your videos!

The video seems to be 1 year old, but still masterpiece to understand data flow/proprty wrappers in SwiftUI. Thanks a lot for such simple and clear explanation.

This was an amazing video for developers who get stuck to understand how properties wrappers work. Besides, Your voice is so soft and your pronunciation is very clear which can mesmerize everyone. I already subscribed your channel.

This video deserved so many more likes. This literally cleared out all of my data flow confusions with swift UI! Thanks a ton!!

New with iOS app development and man, a lot of those property wrappers have been explained here which can easily be understood. Many thanks to you sir! Keep up the great videos - you've helped a lot of beginner devs here.

Dude your walkthroughs are so good. Super thorough, relaxing and information filled!

You explain things much better than Sean Allen. I immediately understand your videos, great job! I like how everything is from scratch and how it builds up.

Awesome video. This literally cleared out all of my data flow confusions with swift UI! Thanks a ton!! It deserves many more likes. Best video on this topic. Appreciate your effort for explaining it in nice & clean Manner.

This was a very well-done explanation! Your style of walking through each combination of wrappers and properties really cleared up much of my previous "fuzzy" understanding of these property wrappers. Thanks Chris!

Great video - I love it how it shows different scenarios and various tools used to solve issues

Hi, Cris. Thank you for uploading these about Swift. I'd beed desperate till I found your channel. I found the best videos for starting to study the Swift! Awesome!

Thanks for the awesome video on environmentObjects. You made it super easy to understand and I appreciate the time and effort you put into making it. Keep up the great work!

Very good summary on data flow! Thank you!

This cleared up all of my confusions. Best tutorial on youtube. Keep it up Chris🙂!

Amazing, very well explained! thank you Chris!

This is an awesome video. I feel so lucky to have access to this youtube channel.

You made it easy to understand

Thanks for the lesson.

Very nice and down to earth ;) thank you!

Very clear walk through, thanks Chris!

thanks a lot, this is the best video about data flow in swiftui, great job

Thanks a lot that makes me understand well about data flow

Thanks so much Chris as ever clear. Understand this clearly now.

Thank you for this video, it was excellent. Liked and favorited!

Great Tutorial, thanks for this!

Great job Chris!

Very helpful! Thank you!

Such quality explanations. Thank you as always!

Good explanation bro ! Thanks !

Fantastic and clear explanation, thank you so much!

Very very very Good explanation. Well done Chris. Tell me where do you collect those information as developper? When I read the Apple document without exemple. it's very hard to understand.

Plz include StateObject... In the follow up video

still great two years later

Such a good tutorial

I would KILL for you to teach Java, you're leagues better than my college professor.

How would I get what the user types in TextField over to another view. I can't seem to get use the property its held in to do so? Thank you.

excellent review

Hello, thanks for your work. At 17:17 shouldn't the first line be @ObservedObject var myObj = MyObject() ?

Wow, this was super helpful Chris, thanks for putting this explanation together. Also, it sounds like you are using a custom mechanical keyboard, or maybe I'm wrong. What keyboard are you using?

Amazing!!!!!!

I saw the video, great explanation, but I so simple, I'd like to know what happens if you need more than 1 enviormentObject. For instance, we have a model Company and model User that models are used in many parts of the app what is the correct way to pass 2 enviormentsObject and reuse that 2 models executed one time the user init session.

You're the the best

My man 👍

masterful explanation Chris! 👏

Great Video .. Thanks :)

Thanks!

What if I want to use 2 EnvironmentObjects of the same type? How do I specify the exact name of the variable in the root View?

Thank

Nice explanation Arthur! Is it possible to change an observable object in another class? I have my logic going on in a separate class and would like do make some changes in states viewable in the view file?

A small typo in the slide on ~17:12. It should be "ObservedObject" instead of "ObservableObject" (although you said it correctly :D)

How do you reformat the code ?

Thank you

What is a “View”

good

At 17:17 you say @ObservedObject but the slide shows @ObservableObject. But man am I loving these breakdowns. Watching it right before an exam😅

Thanks!!...Very well explained with example..

It's really helpful. Thanks!

This is very detailed, simplified and well explained. Others always tried (no offence!) but failed to give good examples like this. Thanks for this treasure.

I took your 2 initial iOS courses 6 years about back in 2015 and been working as a professional iOS dev for 5yrs now. came back to learn swiftUI. still high quality content, nice! wish I could like this video multiple times.

Thank you so much for this video! Just yesterday I was googling the exact things you've described in this video. It really does help to understand how things work in SwiftUI.

Sir, this really helps me to understand concepts. Thank you for such a good video :)

Woow such great Tutorials. I already have done the Cardgame App 😊 How do you proceed, if for whatever reason you want to create twice instances of Profile and use it with the property wrapper "EnvironmentObejct"? Would you have to create a constant for each instance (ex.: myProf1 = Profile () ) and then call the two references with the modifier EvnironmentObject? English is not my native language, hope you understood it anyway ^^

Wow, pretty informative and interesting! Thank you

Your content is amazing

You do a perfect job. But there is no way I can learn all from you. Need some more structure. Especially missing coredata.

👍

Wow thanks for this video now I understand...

How can download the code with Chris phone or laptop and koputer

Dude you explained in easy way..thanks.

Great video

Hey Chris! Love the videos! I’m new to apps. Anyway you could make a series on how to make a app like Tik tok that let’s the users upload their videos?

Hi Chris, thanks for the excellent tutorial. Here's a couple of nuances that I've recently noticed in how @ObservedObject publishes changes and triggers redraws: 1. if your Profile class had a second @Published property that is not used in the layout code, any changes to that property would trigger a redraw of the view anyways. 2. setting the same/current value to a @Published property (e.g. isLoggedIn = true when it's already true) will trigger a redraw of the UI 3. contrary to #2, the .onChange modifier will only react to new values and won't be triggered when setting the same value over and over

Hi Chris! I like your tutorials and I learnt a lot. But there is one more thing. I would like to integrate a print function for the AirPrint (SwiftUI). But unfortunately, I couldn't find any tutorials for this topic. Is it possible to integrate a printing function for SwiftUI at all? If yes, where could I find these information/tutorial? Thanks a lot. Peter🙂

Thank you very much for this informative video! It was definitely very clear and simple, and I now have a better understanding of this topic (which I must admit, I was having a difficult time understanding)

Wow super you just made my Sunday productive......👍🏻👍🏻🙂

I finally managed to understand them all! Thank you so much for this tutorial Chris! You are awesome! :)

You are awesome teacher Chris :) Thank you for the valuable information.

Man, your explanations are excellent. Thank you for this!

What an incredibly clear explanation. The examples really bring it together. Quite possibly the best I have seen on RU-vid!
