It is mandatory to read part2 before continue this Async Sequence A type that provides asynchronous, sequential, iterated access to its elements.AsyncSequence is a protocol describing a sequence that can produce elements asynchronously. …

A linked list is a collection of values arranged in a linear unidirectional sequence. A linked list has several theoretical advantages over contiguous storage options such as the Swift Array: - Constant time insertion and removal from the front of the list. - Reliable performance characteristics. As the diagram suggests…

It is mandatory to read part1 before continue this , OR if you have idea how async/await basic implementation Apple released the beta version of Xcode 13.2. Besides the latest versions of the SDKs, it also brings backward compatibility for Swift’s new concurrency system. Until now, we could use async/await…

Synchronous / Asynchronous Function In Synchronous function your thread is blocked and waiting for that function to be finish In Asynchronous function your thread is free to do other work when it’s done it will notify you by calling it’s completion handler OR you call function and then in return function call you at…

Orange View In Figure 1 as you can see Orange View constraint from top 37 , height = 400 , leading and trailing = 0 In Figure 4 you will see the globalFrame which is distance of that view with window if specify nil , so for orange view there…

At WWDC 2019 Apple announced a couple of really cool features for table views and collection views. One of these cool features comes in the form of UITableViewDiffableDataSource and its counterpart UICollectionViewDiffableDataSource. These new diffable data source classes allow us to define data sources for collection- and table views in…

As shown in Figure 1 data sources today, in UITableView and CollectionViews? So here we see an example implementation of the UICollectionView data source. Now, if you’ve worked with UITableView or CollectionViews, you’ve seen this before. Here, we’re providing three of the required two methods in this protocol. And it’s…

In previous part we covered the advanced topic of compositional layout . In this part we will be working with supplementary view . Now that we are comfortable with the base implementation, this part of the series will focus on the Supplementary Items and Decorations that we can use in…

In previous part we covered the basic of compositional layout . In this part we will see more advanced topic. Compositional Layout with Custom Model As shown in Figure 1 we created collection view cell called topApp in App Store
