What a video! Honestly, if KZbin had MVP awards, this would be it!

[@liudasz]

That's for sure, all clear !!! :)

[@alexpascal5403]

See Paul’s hair? He’s aged more than avg. because of his iOS development obsession.

[@Enderia2]

Definitely not the Minimum Viable Product, idk what you’re talking about

[@42sol]

I can only underline that. I will shurly use your advice and your great material

[@OurFantasyLife]

This has solidified my decision to learn Swift in 2022. I've been half-heartedly trying to learn a language for the last 5 or so years, time to buckle down and like you said, get rid of "shiny object syndrome" and just commit to learning it. Apple isn't going anywhere, and while it might feel "limiting" to learn a specific language, it does open you up to developing for Apple's entire ecosystem, which is nice. I really just want to build a scriptwriting app for myself, but learning the skills that will let me do that will lead to another income source for me as well, so it's a win win.

[@leonstone3443]

Im right here with you!

[@colgates.]

Thank you Paul for your tremendous contribution to the community. I'm enjoy your videos, always makes me feel better. I love when the dogs come in. Have a good day!

[@franciscobarafani6792]

I’m a Semi-Senior React Developer and I’m really interested in learning native iOS development. I found your channel and it’s helping me a lot so far, thank you for your great job!

[@TaelurAlexis]

Literally same!

[@lembueno894]

This is almost as long as a college lecture, and I did not wan't to close the video or skip ahead once. Good video!

[@davidmancuso9792]

OK, me: the mistakes: 1) Memorizing - Got it-I've espoused this to my tech students for years. 2) Shiny Object Syndrome - Man, I thought that was a good thing. Back off, ADHD. 3) Lone wolf learning - Um, that's my main M.O., all my life. How does this Paul know me so well? ;) 4) Relying on Apple's documentation - Man, I was using that for late night reading material. ;) Seriously, point taken. 5) Getting lost in Objective-C - You are preaching to the choir, Master Hudson. 6) Taking shots on other languages - Good advice, especially when a lot of the jobs I see use other languages or scripting in conjunction with Swift (e.g., PHP). Excellent video, worth repeated viewings to help keep a focused perspective. Except the 4-5 hours a day-for me, I need to be soaking in it, and I don't want to do anything to stop this ball from rolling as well as it is. I guess everyone may have one exception to the rule.

[@marcoespinoza3327]

Goal is definitely to get an iOS dev position for me and I’ve failed a few first-round interviews. It does feel a bit discouraging at times, but I know I will get better and will eventually land that position I’ve always wanted. Thank you Paul for all the free content you provide to the community and it’s much appreciated 🙏🏼

[@twostraws]

Best of luck! 🚀

[@MrSojek]

Have you finally got it? And were you applying for a junior dev?

[@marcoespinoza3327]

[@tomasleitao]

Hi Paul! i'm just starting with your tuturials, and I love the passion you have teaching! I hope to learn more with you!

[@CésarManuelCuervoOrizondo]

Hello Paul. I just started your 100 Days of SwiftUI course, and I must say that this first video has been very inspiring. Thank you for your time and dedication in making this course free. You are a wonderful person and have great communication skills. Plus, you have two adorable dogs. It's clear that you are a fabulous person. Thank you.

[@Einfachissa]

Now im even more tempted to learn Swift and SwiftUI. Your course was recommended to me a thousand times and im starting a bootcamp in a few months and for preparation im using your course. thank you so much for the work you've put in!

[@EricsWormPlayground]

How did it go? What sort of bootcamp did you connect up with?

[@jizhou749]

Thank you Paul, you encouraged me to keep learning my swift & swift UI. I have learned 3 months and know how to do some basic mission. To be honest, it is not easy for me as a rookie in coding industry. I really hope you can make a video to show all the new learners about the routine job we need to do as an ios developer. I am so confused about how to use what I have learned to do works or finish the missions. Thank you. Subscribed.😄

[@fireballgfx]

I'm already a senior software developer (C/C++/Java etc.) on Windows and Linux, now I start again as a junior on apple system - I'm so excited! :-)

[@jizhou749]

37:42 I feel so exciting, I am learning Swift UI from Chris's videos.

[@gordongao9958]

Thank you, Paul! I'm starting my Swift study journey.

[@rahulek914]

Paul, thanks for an excellent overview of the iOS landscape. I am venturing into learning iOS not for a job but as a new field to learn on my continuous learning path as I retire from my 35 year career. I found this overview very useful and focused on important points that really matter. I hope to gain some quick iOS ground by following your advise.

[@mugenr]

Always nice to watch this video once in a while. The code so bad you’ll break the Geneva convention section keeps me going. Thanks again Paul, really appreciate it.

[@terhohenriksson2784]

Simply the best course of iOS ever. I know it from this very first video. I am taking this 100 days challenge on SwiftUI. Thanks Paul!

[@michaellaw4762]

Day 1 today. Great video. I'm not sure whether to be scared or excited. Scratch that, it's excited.

[@kennyho6222]

Thank you for your guidance. I love that you mentioned having more willpower because that is important for people like me to not rush or skip ahead while learning the core skills

[@Kyronsk8]

I’m really happy I watched this video in its entirety. Sometimes I stop working on my project for months because I’m afraid to ask a question on stack.

[@GKNaidu-hb5zv]

i am confident that one day i will be a senior ios developer and the reason behind that confidence is paul hudson..

[@abdi5120]

Same

[@lawrencewayneaustin5790]

I am so grateful for all the continuous contributions in which Paul Hudson makes… sometimes i feel i dont know if I’m able to break through certain learning barriers but just watching his videos and reading his books give me confidence to become relentless in my thought process and applications in learning swift by understanding the basics and go slow to improve faster and better in the future…Thank you so much :-)

[@petercimring4817]

Superb overview, packed with practical wisdom & links to valuable resources. Thanks, Paul!!

[@HominisLupis]

What an absolutely gorgeous doggo, Paul! A thousand kisses and pats!

[@ram_bam]

Paul, you're an awesome human being. Thank you for existing.

[@Rohinex]

Thank you Paul I have spent a lot of time learning different programming languages but you encouraged me to start a new journey with Apple and swift. Thank you again.

[@alephme]

You just gave a very clear path for my returning to the developer's world. This video means a lot to me and watched it twice

[@alessandrogentil]

I just got a Senior Software Engineer role, main with react, just to know that I love the little things that I have done with swift just for study, now I will study every night, weekend, holiday, until I got maybe a mid-level Ios Engineer at the end of this year! Wish me luck! Just started a clone of the Netflix app!

[@Eugene.Berezin]

It’s a great explanation ! I would put UIKit in core skills. I’d point out that you need to know UICollectionView, UITableView, auto layout, text field and text view and segmented control. I’d focus on very basic principles.

[@MdGmRsnbd]

I totally agree with you

[@RobertPetras]

Not really in my opinion. New developers are better off focusing on SwiftUI and Swift.

[@Linkzelda99]

29:20 I love the lone wolf in a pack lmao (but I do see your point)

[@hoatran-lv5rj]

Thanks Paul for your encouragement and conscientous teaching and guiding.

[@selcukdag]

This may be most helpful resource for learning ios development! Thanks Paul!

[@darrenmiller3689]

An incredible resource for someone getting started. It’s easy to get completely overwhelmed with all of the information and learning paths. Thanks for distilling it down for us!✊🏼

[@dpacheco9588]

Well, first of all, I thank you very much for making this video. Almost 1 year ago I arrived in the United States and I started from 0. I currently work at a McDonalds but I have always been interested in the technological world and today, researching and watching your videos, I am motivated to start my learning in the world of mobile development for ios . Thanks to you I have the general topics that I must cover. Now I am looking for a roadmap to delve into each general topic that you gave and know which route I should follow or at least where I should continue to be guided to start this adventure. I love apple and the entire ecosystem, I will persevere on this path.

[@citizenken8540]

So glad to have come across this video. Put's everything in perspective for an absolute beginner. Thank you Sir!

[@natgenesis5038]

You are the best wow ,because most of people present us a lot of things

[@srbalan1995]

When I see the title, I said to myself to watch just the first minute as I already have a job as an iOS developer, but Paul put so much effort to this and this is very helpful and informative so I ended watching the whole video. Thanks Paul!

[@NikitaProkudin-ku9ow]

Paul, thank you! I'm just beginning my journey and am very happy to find you and your channel. You have given me a plan of action that I will follow for as long as I need to.

[@SecondJourneyAdventures]

Absolutely fantastic video, specifically for someone new to programming,

[@haninb7679]

You explain everything so beautifully that every time I have a problem I go straight to your website and bam! You’ve explained it there. I just want to thank you and say that I appreciate your efforts.

[@jimkika]

I started making some simple interfaces on swift UI but then I felt lost in where to go next. This video helped me to get back on track. Thanks

[@DanielBerggren-t5n]

great video. keen on starting your 100 day course now! just a tiny FYI: some of the twitter accounts in description no longer exists.

[@a.inozemtsev]

Described mistakes are not only about Swift, but they are more about general teaching rules for all the programmers That’s incredible thoughts for beginners and even regular devs

[@krishnaamen]

Great video as usual.

[@breakthecode119]

Thanks Paul, Great advice.

[@aaronb.7751]

Hi Paul - I am a beginner and about to embark on the 100 days of SwiftUI journey, but I have one question... is this course from 2021 still 100% relevant today? Or have there been any changes that make parts of this course... different than Swift/Xcode/etc. from 2023?

[@Adrian.katzenstein]

Yes, learning Swift before SwiftUI is still a valuable and highly recommended approach in 2025. SwiftUI is a declarative framework built on top of the Swift programming language. To use SwiftUI effectively, you need a solid understanding of Swift fundamentals.

[@pjnanmirabelli4579]

I put this comment in the first 50 seconds to just say that this Paul is very a nice guy , I like the passion he has for us

Thank you for the thorough overview, Paul! I'm transitioning from a web dev role to iOS development bc I love coding with Apple devices/the community. This lays out some stuff I need to explore for sure, will try to start with 100 days of SwiftUI!

[@eaji8853]

Thanks, this is really helpful. I was planning on learning Objective-C as an extension skill, but thanks to this video I'll learn SwiftUI instead. So it's probably saved me a lot of time. Thanks again, and I've subscribed.

[@llothar68]

Objective-c is still the way to go when doing multi platform as it binds perfect with c++ libs and business layer

[@mahbuburrahmanmishal5106]

In the description time frame is wrong 11:50 is Extension skills that set you apart

[@twostraws]

Thank you! I've fixed this now.

Paul what a great intro. Juan

[@matthewgarber5517]

I currently work at a large company as an SDK developer which is used by all of our clients. Some of which are mobile apps, and I have been leading the teams push to move to SwiftUI and all of our newer internal features are built using SwiftUI. But its taking time since SwiftUI wasn’t really usable until iOS 14 and we have to support older OS versions for user facing features. It seems like a lot of big apps target versions as old as iOS 12 so I’m guessing SwiftUI is around 2 years away from being a real UIKit replacement.

[@ugurgeredeli312]

Thank you, You cannot imagine how this video help me🙏

[@agungtheprofessional]

Just finish watching . This is amazing videos. This motivates me to continue the Ios developer lessons. Thanks for the advice.

so i learned swift on my own and at my own pace for a year or so and then quit before the pandemic hit...looking to get back into it, hopefully this video is still relevant for 2022....thank you

[@randlyce]

I love swift since last year June 2021 and did a udemy course for 6 months and stopped because i was interested in machine leanring but after watching your video you're right i shouldn't beat my self up it takes awhile since i started at 0(no background) it might take 1 year thanks for the video its been really helpful
