How to use inits and enums in SwiftUI | Bootcamp #13

[@markjensen5015]

I've looked at 3 books, and two paid courses, and Apple's own SwiftUI tutorial, and this is the best approach by FAR! Also, way better than anything I've seen on KZbin. Well done!

[@SwiftfulThinking]

Thanks Mark 😁 let me know if you have questions!

[@zerezc]

same here, finally got out of tutorial hell with his explanations

[@rishabhbhatia1847]

Brilliant! I was doing "Hacking with swift UI" by Paul Huson before this but your explanations are way better and intuitive. Plus, you cover everything around the feature your are explaining with such ease and clarity.

[@natgenesis5038]

You deserve an Oscar I've been learning SwiftUI from you so far since the first step ..

[@thyself125]

Holy shit dude! You are changing lives. You are demystifying this like crazy. I didn’t even know you could that in SwiftUI. I learned about swift basics but didn’t know the SwiftUI and swift structures were that same in the sense that they can have initializers. Gears are turning in my brain. Thank you!!!!! I can’t thank you enough.

[@SwiftfulThinking]

Hahaha if you thought this one was crazy just wait 😎

[@pitmanra]

The init discussion at 11:00 is very helpful.

[@benceylan273]

I understood init() for the first time :) Thanks mate!

[@SwiftfulThinking]

I could not be happier to hear that! It can definitely be confusing, but doesn't have to be :)

[@leyfqq]

as always the best lessons on youtube ever

[@yuchen3587]

The pace is not too fast nor slow. It is just perfect.

[@SwiftfulThinking]

Haha thanks Yuchen :)

[@Lvoonok]

You are literally amazing, thank you for all your hard work and videos. I have learned more from your videos than reading documentations 🙏🙏🙏

[@pablo5433]

My friend, I was about to give up SwiftUI and start studying Flutter😅, but thanks to your videos I have learned in a few days what I could not internalize in months. Thanks!!

[@SwiftfulThinking]

Hey Pablo! I'm glad you stayed with SwiftUI! I think it's a much smarter path to go down :)

[@ovadianyc]

The ios courses I take on other places, nothing is as clear as your explanations. This is by far the best. Thank you for your effort.

[@SwiftfulThinking]

Thank you!!!

[@yourbestsail]

Just a stupid comment for precision's sake. The forward slash is this /, and the backslash is this \. Thank you for your excellent course.

[@rayhaanalykhan]

You know the funny part, this wouldn’t been a lot harder video, if I wasn’t already a UIKit developer who just came here to learn SwiftUI specifics in depth, so far the course is extremely well organised, especially for me because I like to do it slow but in depth.

[@ferusinfo]

As per discussion in 11:26, SwiftUI is not just "smart" - it works across Swift as a language: "Swift provides a default initializer for any structure or class that provides default values for all of its properties and doesn’t provide at least one initializer itself." This bootcamp is the greatest thing that exists for iOS developers - not only juniors, but seniors like me as well.

[@shivammaheshwari8465]

Yep, correct and also I believe since all views in SwiftUI are struct, and in Swift struct created automated designated initializers, that's why no need to write the init implementation so far

[@ThiagoMenezes-l4m]

Eu sou br e acho q ngm vai ler isso, mas namoral que série perfeita, finalmente entendi para oque serve enums, nunca soube para o que era, valeu cara, tu tá me salvando muito.

[@lifegivesuslemons421]

best course ever. you my friend are a gentleman and a scholar. I salute you.

[@comics-on]

Man, everything about this course is super helpful. However I'm glad to did a Swift programming course before this. I believe learning and mastering SwiftUI is already a daunting task without having to learn the language simultaneously.

[@spradohak]

This video caused some light bulbs 💡 to go on in my head , as simple as it was but it really helped me to connect some dots. thank you so much for the quality content.

[@taosade]

I can't believe that's actually free! Thank you man! Your videos are BY FAR the best!

[@thematturlookingfor]

Dude this series is amazing. Im gunna make sure and give you a shout on some socials, these tutorials are just so ridiculously well done and should be top of the heap for people learning. Thanks for making them🤘🏻

[@SwiftfulThinking]

Haha thanks glad you’re liking them 🤙

[@Dorothyinstead]

To a lay person this subject appears quite daunting. However, as with all your previous videos Nick, your teaching style makes it much less overwhelming.

[@SwiftfulThinking]

I really appreciate these comments. Thanks for watching Rob! This is probably the hardest video in the series so far haha

[@michelcusson2673]

This is the best video I've seen on youTube.

[@SwiftfulThinking]

All of KZbin? 😂

[@Денис-ж3ф5р]

It is all related to Swift on to SwiftUI. Very basic level. Unluckily, I'd already known this stuff before watching, unluckily because the explanation is flawless even in X2.

[@muhammedturk_22]

It is the best education set I have ever seen. Thank you...

[@DannyBoy443]

I really liked this video. This was a high level but understandable yet useful high level code video.

I am so happy that I've found your channel. Thanks a lot Nick

[@SwiftfulThinking]

Glad you enjoy it!

Day 2 of learning and really enjoying it. Thank you for such an amazing course.

[@SwiftfulThinking]

I’ll watch for your comments as you go! Good luck 🤙

[@yurialenccar]

Thanks for the explanation of init(). Totally helpful. You smashed it and has become easy for beginners.

[@ConfidentlyRong-jo5yt]

You're an amazing teacher! Cannot thank you enough for helping me understand init() :)

[@dr.craigcurphey4829]

Once again I haft commend you on your approach. If you ever start some sort of support or consulting offer I would be very interested. Plus I believe by the end of this course I will be able to do my very unique app for which there is nothing else out there. Many thanks!

[@SwiftfulThinking]

Thanks Craig! I'm just glad someone's learning something. It makes making these videos all worth it!

[@knowledgeispower4953]

good bro..😊

[@samarghourab5545]

Hi there, thanks very much for these very helpful videos. I completely followed along the whole way through. I was just surprised we could change the view through the PreviewProvider (struct InitializerBootcamp_Previews) as opposed to only struct InitializerBootcamp: View. Is this a common practice or is it unlikely we would need to change the views in the PreviewProvider? I just imagine it getting complicated if the UI was complex and had a lot of components.

[@SeniaSer]

Hello thank you for lessons but i have some error (missing arguments for parameters 'backgroundColor', 'count', 'title' in call)

[@vortex5896]

good video

[@rasheed1andrew]

I created an initializer that creates a row for a list. I created this same row before without the initializer but I think the code looks neat when its created as an initializer. this is where I find a problem,. on the last row I created, I was able to create an image that has an on tap gesture which updates the ui for the row. pretty much a subscription icon that changes color depending on what state the subscription is in. the function to update this ui is from a view model. do I add this function in the view where the instance was created and how? or do I add this function when I call the initializer in a different view within a list?

[@Jeff-zc6rr]

Why does it also require me to have an input parameter in the @main WindowGroup file and yours doesn't?

[@jcclcreations7909]

Was a Switch statement not used because this is a beginner course or is there another reason for it?

[@Jeff-zc6rr]

Missing argument for parameter backgrouncColor in call.

[@Аселичка]

Hi! Thanks for the video. Did everything as you said till 7:04, but after resume the system says: missing argument for parameter ‘backgroundColor’ in a call… what that might mean?

[@aslanmmmdli1476]

the same here. did u solve it?

[@Jeff-zc6rr]

How do you make two frames show by putting it twice in the PreviewProvider? I have to put them in the original @main file twice.

[@Jeff-zc6rr]

Holy jesus.. there are two preview screens .. One for the App and one for the current window.

[@heismyke]

Return from initializer without initializing all stored properties i got this error

[@GabeColors]

At 17:30 you say “when we type a period” how would I know that?

[@SwiftfulThinking]

Haha that's how enums work! We create an enum with a bunch of different options and then when we go to add one, Xcode automatically gives us the autocomplete with all of the options. I highly recommend using enums as much as possible!

[@m__link6499]

What's wrong with this code please ? 🤔 struct ContentView: View { let name: String var body: some View { Text(name) .padding() } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView(name: "john") } }

[@SwiftfulThinking]

Hello! I copied and pasted the code and it works fine. I don't see any issue. Are you getting an error message?

@@SwiftfulThinking Now suddenly I works...Very weird 🤔...thank you and keep going...Your videos are powerfull!!!

[@user-goldeneunga]

Can you please teach me what self. means?? I'm really confusing..

[@SwiftfulThinking]

self refers to the object that you’re in. So if your within a class and you call self, you’re referring to the parent class. I’ll try to do a video on this soon!

[@user-goldeneunga]

@@SwiftfulThinking Thank you so much!! I'm learning swiftUI so well thanks to you!! You have so good pronuciation that me, Korea student can easily understand the video Thanks!

[@belveloper]

Self is the same as this in other languages Like dart java ...

[@pitmanra]

At 8:05, that's a backslash, not a forward slash. ; )

lol oops -__-

[@m__link6499]

6’57 : why it doesn’t work for me when I fill the previews ?

[@SwiftfulThinking]

What error message are you getting?

[@Денис-ж3ф5р]

It's not that hard if you know Swift language and switched from C#.

[@gucp]

Do I always have to use self.something when the conditional is within an innit? Is there another video explaining the use of self.?

[@SwiftfulThinking]

No you don’t need to use self. I was doing that to be clear in the tutorial that self. refers to the variable in the struct and not the variable passed into the struct (since they have the same name)

[@gucp]

@@SwiftfulThinking thanks! It makes sense now

does this not work in 2024?
