map is a higher order function and helps us in doing data transformation with ease, but there's one behavior of map which every iOS developer should be aware of and today we will be seeing what that behavior is so that we can use map more effectively and at the right place in our project code. Please feel free to ask questions on this topic I will be happy to answer them
Thanks a lot Ravi bhaiya!
Thanks Yash, am glad this video was helpful 😊
How can i convert [ [“key1”:”value1”], [“key2”:”value2”], [“key3”:”value3”] ]
To one dictionary??
Hello Hiren, you would need to use flat map for that because your dictionary is inside a collection
Here's a link to the gist I created for you do check it out: gist.github.com/codecat15/21d3adf5b890aed1715cd1d4cf92831f
Hope it helps
I like most the "KRANTIKARI" advice
Am glad this was helpful Sumita, welcome to the channel
Hello Ravi..I like your videos n way of teaching but I have confusion in somewhere I see $0,$1,$0.1,$1.1 and please also explain other possibilities like this ..

Hi Ravi...your videos are amazing... can you create a playlist on combine framework also
Hello Ramcharan, welcome to the channel. Yes there soon will be a loaded playlist on the same. If there’s a specific topic for combine you can think of then please do mention i will add it in the list. Do subscribe to the channel and share it with your iOS group on WhatsApp or Facebook 😊
Code Cat lets start with basics. What is async programming? Benefits of it? Publisher, subscriber and operator are key basic topics to start with
Combine framework works on the principles of observer pattern and functional programming, I did explain what is a publisher and subscriber in the observer pattern video so do check that out. The list you gave is solid and I believe it touches the core concepts I will add few more to it and will have a detailed video rolling out soon.
Thanks for suggesting this @Ramcharan
Sir please make Objective-C tutorial video.
I would recommend using Swift than Objective C because this is what's widely used for building iOS apps and majority of the apps are updated to Swift so my recommendation is to learn Swift.
@@CodeCat15 I know sir if we want to get a job in iOS development so we should have a knowledge of Objective-C also.
Objective-C is good to know but Swift is a must, unless the company where you gave the interview works only with Objective C then it’s a different scenario altogether
Great videos
Thank you
Keep it up
Wow! I was not knowing that map can be used with optional types! That is the reason I am watching all the videos I getting to learn new things from each video ❤️❤️❤️❤️
I am glad that info was new to you, glad this was useful 😊
And wo kraaantikari advice b mast thi 😂
😂😂😂😂 aare bhai maintainence ki duniya mai bahut papad bele hai, coz kaisa hai tum kya use kar rahe ho uska behavior tumko malum hona chaiye ki isko kaisa data pass kiya to ye kaisa respond karega, varna hoga kya ki tum use karogaye ek dum excited hoke but output kuch aur aayega fir dil k armaa aasuo mai beh jayengaye to aisa na ho isliye ye chetavani pahele he de daali maine
Code Cat 😂 Ye chetaawni achi thi or zaroori bhi 😅😅
