- Struct vs Class is the favourite question of interviewers and after WWDC 21, Actor made this question even more difficult. Most of the interviews start with this question, and the answer to this question decides direction of the interview (decides follow up questions).
In this video, I’ve discussed struct, class and actor (in brief) and 12 frequently asked interview questions on them. Also, I’ve discussed the answers in such a way, that you would be able to answer any question around them (apart from the 12 that I've discussed).
Hi Pallav, This is Syed Abdul Basit from Pakistan. I am really thankful to you for providing such brilliant content regarding iOS development. I had my interview last week and, in the interview, there were 2,3 questions like Copy on write, Dispatch methods which I cleared due to your youtube videos, and luckily I secured the job offer from Canada. Once again thanks brother for these videos.
Hi Syed, Can you help me on how you secured offer from Canada? I am also looking for a job change. I am from India.
So far the best tutorial comparing class vs struct! thanks a lot!
very well explained Pallav 👏 !!!!
Thank you so much for the effort!
Best video on a subject so far, and I've seen a lot! You got yourself a new loyal follower now✨ Keep it up!
Love all your content. Please continue the System Design videos for iOS!
Awesome Explanation with each and minute details , which will helps not only for experience iOS developer but It also makes the pillar for those who just started the career in iOS.Thanks man!!
Very clearly explained. Thank you and good luck for more such contents.
Amazing content!! Thanks Pallav.
You help to improve my Confidance.. Thanks a lot for such a nice explaination
really superb!Most of the questions covered
love your video's and efforts.... just a friendly suggestion, believe you speak too fast, i refer your video's to my teammates and they get lost and have to revisit video multiple time for some of the concepts
we all could be wrong here but thought to share
Wow fantastic knowledge and explanations 🎉
Super cool information. Well explained
Sir can we get a video on POP in Swift. How actually implement it I mean there are videos on it on you tube but then I am sure u must be having a different perspective and a more easy way to explain it.
And SOLID principles using POP in consideration.
Thank you in advance. Great tutorials indeeed.
This channel is gold
Brilliant questions & explaination sir..I would like you to continue this series & involve concepts such as core data , data security such as pinning, API security, generics, Protocol oriented programming, thread safety including race conditions, dynamic vs static dispatch, efficient memory management , Singleton vs DI, Architectural patterns etc...
Thanks for the kind words Jayant. I've already covered most of the topics suggested by you. Please go through channel's videos section - th-cam.com/users/iCode_Happy_Coding/videos
I'll try to cover the remaining ones soon. Thanks 🙂
Awesome explanation!
great work .. 👏🏼
very valuable content!! Thank you for your channel, immediate subscriber!
I will keep this video as a reminder of the answer to the difficult questions
This is gold level video
Excellent video bro
This is fantastic!
Excellent video. Thanks Pallav
Thanks Dhaval 🙂
Awesome video
Great video ...
Hello Pallav,
One question. value types get created on stack memory and class types on heap memory.
now if any struct is created in controller where memory gets allocated?
as per 08:14 on heap
if this is true then for any app there structs are always allocated on heap.
Is tere any way to check where memory for that instance gets allocated
Can you please explain when to use sqlite, core data, realm.
Video is very helpfull.Can we get similar kind of question sfor latest swift version 5.10 and nowdays what set of questions are being asked in interview?
Really good and trending questions you explained here ..! Thanks 😊👍
Happy that you found the video useful 🙂
Very Informative . Can u please cover the topic network architecture in a project
Superb Thanks😀
In API Call Model class, what we can use Struct or Class?
NOw thats the content i was looking for
Millions of Thanksssss for amazing content🙏
Thanks Puneet 🙂
Very good video thanks for it but like to as is function is not a reference type?
Awesome once again ...keep up the good work.
Thanks 🙂
Well explained
Helpful, thanks!
Please create demo on Struct being thread safe and also when using reference type as a property in Struct then structs are not thread safe. When we can have data race condition in this condition.
One example only with struct with properties of value type so while accessing them in different thread is it thread safe or not.
Looking forward for this analysis.
Hello sir, Can you please share the video for closures
Nice explanation sir with each and every minued details
Thanks Sudheer 🙂
Can we restrict to take screenshot in iOS app?
Man!!! this is great 👍
Thanks 🙂. Glad that you like the video.
very fruitful thanks
Glad that you liked the videos 🙂
Your videos are like gems to me. Thanks. Request: Video on downloading data in background and its policies and possibilities, background fetch etc are really needed.
Background downloading while app is in bg mode, while app is killed how to manage the content.
Thanks for the suggestion. I'll definitely try to cover it soon.
Glad that you liked the videos. Thanks 🙂
This is actually a very good question.
@@iCode_Happy_Coding Is there any video that came out for this? I just wanted to understand how any application downloading multiple videos or audio or any file type in the background. eg wynk music or and downloaded. work.
Please more content on System design.
Very informative. Thank you.
Glad it was helpful!
Why swift language called protocol oriented programming language (POP)?

2:04 - "Classes can be deinitialized"
This is a little misleading. We on our own can't deinitialze classes, rather we can just use deinit() to "know" when the "system deinitializes the objects" of a class. We can not call deinit() explicitly anywhere. If we have definied this method in our class, the system will call it and execute whatever code it contains at the time of deallocation of that object.
doing gods work
Thanks Pallav. The video is really informative. By the way, let me ask you a question. Why we use Class for implementing UIViewcontroller instead of Struct? Obviously Struct doesn't support inheritance.I understand that the system is executing a number of super class methods automatically by inheriting a class from UIVIEWController. In addition to that, we need a reference type object in the case of a UIViewController . Is there any critical problem apart from this for not using struct instead of class. After all struct is faster and thread safe on comparing with Class. Correct?
But then u gave the answer already. Inheritance is the purpose.
I guess the actual reason should be that the classes are reference types. A viewcontroller's lifecycle can be as long as the app's lifecycle. So, by making it a reference type we can ensure that every time we get that particular viewcontroller (from navigation stack etc..) we are pointing to the same reference and if we are making any changes then it should hold that changes.
Awesome
Thanks 🙂
Missing Point
1. Structure not support self Type as property while class support this
Your channel notification means something interesting to learn :)
