Lazy loading & image caching with UITableView swift 5 Hindi tutorial

Lazy loading in swift along with image caching in swift are two most important topics and the most commonly used feature in any iOS application. For the demo, we are fetching images from an API and displaying them in a UIImageView inside the UITableView.

Many beginners when displaying image from the server face the problem of UITableView freeze or having a glitch while scrolling the UITableView

In this video, I will present an example where we use lazy loading with UITableView in swift to resolve that issue. Along with lazy loading, I will also explain how we can cache an image in swift using NSCache.

Now it's important that I say that I am just explaining the general concept of lazy loading and image caching here with a small example of what they are and what problem they solve.

There are way better libraries that you can use which handle many complex scenarios for lazy loading an image like the one I mention in this video which is SDWebImage.

I hope this video answers most of the questions regarding why does the UITableView freezes when you try to set an image from a URL, this video will help you to understand the concept of lazy loading in swift along with a basic example of image caching using NSCache, however lazy loading with UITableView can get tricky and I have tried my best to answer most of it in the video but if I missed something then please feel free to ask your question as comments or reach out to me I will be happy to answer your questions :)

Hello Ravi sir,
Hope you are doing well!!

Can we have one video dedicated on socket applications for video calling apps.

[mahii_lyricz]

Could you please explain thoroughly how to use third party libraries into our xocde project..!!

[lordironman]

Hello Sir, Is my understanding correct ?
You have created NSCache as instance stored property so, the imageCache will store only caching for urls this instance has called. For example 
Let tableViewCell A load image from url -> xyz
and tableViewCell B load image from url -> abc
if now tableViewCell A try load image from url -> abc then it will not find image in cache hence load from server

Am I correct ?

[AnkitSoni]

Nice video thanks, one question -- Third parties like Kingfisher automatically handle caching? or we have to do it manualy.

[Rasikabharati]
