Your selection of topics is so good.

[@iCode_Happy_Coding]

Thanks Keshu 🙂

[@King_Slayer_06]

Thanks for the great explaination Pallav! At 11:57 i was getting suggestion to change the return type to "any Card" instead of "some Card" (Im using Xcode 15.0.1). What is the difference between "any" and "some"?

[@pr1tham]

Very good content, Please keep this up. Thanks.

[@shanmugamsekar4044]

Superb Keep posting🙂

[@seunolalekan8987]

Thanks a bunch man! This was an excellent explanation.

[@vickywang5049]

My takeaways: Generics is the placeholder of types used in functions signatures (like a template). It allows the caller to decide the actual type whereas the function doesn't care about it at implementation. Syntax: func function -> [T] {} Opaque type is a placeholder in function returns. It hides the concrete type from the caller, but the function's implementation and compiler knows exactly what it is. Syntax: with keyword "func function() -> some Protocol{}" Associated type is the type placeholder inside of protocols. It makes protocols more generic. Anyone who adopts from protocols with associatedtype must specify the actual type first. Syntax: associatedtype typename Protocol is the "blueprint" of a set of properties and functions that must be implemented if a structure, class, protocol wants to conform to it. Syntax: protocol protocolName {}

[@vickywang5049]

An example that can be solved by opaque type: If you have a generic protocol with associatedtype, and you don't want to reveal the concrete type of the function returns to the caller, you can use "some" keyword to return an opaque type instead.

[@LittleLearners-junior]

superb videos please keep uploading.

[@ananthakrishna9672]

Great information. I have small doubt how to decide struct vs class

[@iCode_Happy_Coding]

Thanks for the suggestion Anantha 🙂. I’ll try to cover class vs struct in detail (including usage).

[@ananthakrishna9672]

@@iCode_Happy_Coding thank you.

[@MrAbhijithadkar]

You should consider uploading 2-3 videos @pallav. Nice topic covered very easily. Thanks and keep it up.

[@iCode_Happy_Coding]

Sure Abhijit, I'll try covering theses topics in detail. 👍🏼

[@puneetpal1466]

It was awesome... Thank you so much :) 😊

[@iCode_Happy_Coding]

You're so welcome! 🙂

Thank you so much sir

[@ANILKUMAR-vv1fz]

it was awesome

[@abymathew575]

nice explanation bro.

[@iCode_Happy_Coding]

Thanks 🙂

[@deveshtyagi]

Amazing

[@iCode_Happy_Coding]

Thanks 🙂

[@maqusss]

I saw much better example on hackingwithswift. Consider functions makeInt and makeString that both return "some Equatable". Compiler will allow comparison "makeInt() == makeInt()" or "makeString() == makeString()" but won't allow "makeInt() == makeString()".

[@keshavkumar1522]

Thank you so much for your effort in delivering such kind of valuable content on youtube. All your videos are so informative with a practical example. Wishing you and our channel great success. Keep doing a lot. Kindly do videos on MVVM-C, MVP, VIPER Patterns. Most of the developers struggle with animation stuff. So, please do a tutorial series on CoreAnimation, BezziarPath, Custom Layouts, etc. Thanks again.

[@iCode_Happy_Coding]

Thanks for the kind words Keshav. Did a video on Bezier Curves after your suggestion 🙂
