System Design Round (iOS) - Mock Interview | Mobile App Development

[@rajattyagi4602]

Finally some quality content on iOS interviews, thank you so much.

[@iCode_Happy_Coding]

Thanks Rajat, glad that you liked the video 🙂

[@Megan-M24]

Pretty clear interview discussion. This video helps a lot to understand easily with download as example which is an very important example. Made me to understand the System design round, quite clear. Thanks a lot.

[@priyeshp1737]

Thank you so much for taking this topic. iOS SDR videos are very rare, we can find many videos claiming to create Instagram clones, FB clones, etc, but most of its content is related to creating UI only. I am expecting many more SDR videos from you brother. Good luck.

[@iCode_Happy_Coding]

Thanks for the kind words Priyesh, I’m glad that you found the video useful. Will definitely try to cover the System Design round in more detail 🙂

[@nihaomrzhang5286]

I like how you even show when you make a mistake during the interview! Great video! Subscribed

[@mixedvibes2430]

Good one guys. Thanks for this.
I have similar thought. But its good I found it here.
Really appreciate your efforts.
There are numours of usecases/topics can be covered as part of system design round.
Example: Designing PaymentIntegration, Spottify, Netflix, Splitwise, Parking lot and many more..
Hope I will see them here near future.

[@ghost_busters]

[@rajithkumar3424]

This video is very help full for the developers for attending interviews . Trust me , these types of videos are not much especially for ios Platform .Thanks Pallav

[@indomitabletr1834]

Great video, can you explain more why changable metadata is a matter to talk.

[@LifeTravelExplorer]

I am sure Pallav you are going to pitch a revolutionary change for online/video learning and explanation of things

[@ankitpaliwalsati]

Good explanation, your way of elaborate the things is very good, you have covered the many things in this short video.

[@rrahulc]

Thanks for adding a real-time scenario of cross-questioning, Despite having system design exp one can still get some knowledge from it like I learned AVAsset-aggregate download task(Thanks to you) and SOLID principle (Thanks to Tanya). Liked.

[@fhdmsd]

[@Real_Indian_bhartiya]

you are creating such a g8 video, so for more understanding can you please create the video like design the Netflix or any other app . i mean just for more information.

[@iCode_Happy_Coding]

Sure Vaibhav, I’ll look for covering these kind of questions for System Design Rounds. Instagram design is one of the common questions. Thanks for the suggestion 🙂

[@Real_Indian_bhartiya]

​@@iCode_Happy_Coding Thanks a lot to consider my request.

[@kirill4531]

The Single Responsibility principle is still violated in Storage Service.
I guess you should have InpuOutputHelper class as well, to write into disk.
Also Dependency Inversion is also violated. Download Service class should work with interfaces rather than with concrete implementations.

[@cristiansalomongarciaolmed8502]

This is quality material, thank u so much

[@sajibghosh1918]

Quality content! Please keep up the good work!

[@ChhayaAhuja]

Very helpful. Thank You.

[@rameshK-yx8nz]

Good one....Any resources for system design in iOS?

[@iCode_Happy_Coding]

Not really. For mobile developers, there’s literally nothing for System Design preparation.. that’s why I thought of this use case (download).
Glad that you liked it 🙂

[@SushobhitJainiOSDeveloper]

Please explain which data base we should choose? as you asking in this interview for no sql and sql data base. if possible then please create one video for that.

[@iCode_Happy_Coding]

Sure Sushobit. I'll try to cover it in detail.

[@GKNaidu-hb5zv]

Nice content
Please use a better mic ( suggestion )

[@AnkitSingh-wq2rk]

Do they ask System Design Interviews for SDE-1 Profiles too ? I am a developer(fresher tbh 1 YOE) who wants to transition in iOS industry do i need to learn these things too ?

[@nirmalkumarselvaraj3996]

Great video, please upload more iOS SD videos

[@iCode_Happy_Coding]

Thank you, I will try to 🙂

[@surtimanish]

very helpful content.

[@bunnyrabits]

After what years of experience are these system designs questions asked from you ?

[@holatechm]

Really nice video

[@01helloall]

4:57-5:06 - NoSQL db choice in both cases?

[@JJ-up4xt]

hats off to you for bringing a female engineer for the interview. truly inspiring. great content

[@punerealestatebuilder]

lol. and why do you think for hats-off because of female engineer? Does that matter?

[@vinayakthite]

How can we use No-SQL in case of data that will be changing frequently for iOS

[@vinayakthite]

If there is any video for the same then please give the URLs

[@sanketpandya911]

Interesting!! Was looking for such quality content on internet.

[@iCode_Happy_Coding]

Thanks Sanket, glad that you found the video useful 🙂

[@paccini1]

Thank you, great content!

[@ProductsHub365]

taking above design in to consideration .. can you please explain how to manage offline data management on view ?

[@kirill4531]

Would you have one single listener for all downloading events or for every download item you can register individual listener?
If the first is correct why not using a stream of events?

[@dudefy33]

This was really helpful!

"SOLID principle" is not real. It's promoted by Robert "uncle Bob" Martin to sell books.

Yes, I’ll try to cover that too.
