In this tutorial, we will explore how to use the Combine framework in Swift to perform network operations. Network operations are an essential part of mobile app development, and Combine provides a powerful way to handle asynchronous events. First, we need a URL that will return the JSON data. For…

In the world of reactive programming in Swift, the Combine framework provides a powerful set of tools for working with streams of data. One of the most important sequence operators in the framework is “reduce”, which allows you to reduce a sequence or an array down to a single value. …

Grand Central Dispatch (GCD) is a powerful framework that lets you manage and execute tasks in parallel on different threads. While GCD is often used to run tasks asynchronously on different queues, there are a number of lesser-known features of GCD that can simplify complex concurrency tasks. …

Inline Expressions in Swift In Swift, an inline expression is a code statement that is evaluated immediately when it is encountered in the program’s execution flow. The result of the expression is used at the location where the expression is written. Using inline expressions can help to reduce code verbosity and improve code readability. …

In the provided example, the sequence operator being discussed is the “allSatisfy” operator, which is a sequence operator in the combined framework. …

Firstly, the “contains” operator is a built-in operator in the combined framework, which is used to check if a sequence contains a particular element. It is denoted by the keyword “contains” followed by the element that is being searched for. …

Let’s talk about count() operator. The whole purpose of count() operator is to depict that how many values will be emitted by the publisher count() let publisher = ["A", "B", "C", "D", "E"].publisher publisher .count() .sink { print($0) // 5 } In order to demonstrate count() operator, I made a publisher…

Let’s go ahead and check out another sequence operator. This operator is called output(). output() operator comes in two different variations. First variation of ‘output(at: Int)’ operator let publisher = ["A", "B", "C", "D"].publisher publisher .output(at: 1) .sink { print($0) // "B" } To show how output(at: Int) operator works, I created a publisher with array…

Now let’s go ahead and take a look at first() and last() operators. first() let publisher = ["A", "B", "C", "D"].publisher publisher .first() .sink { print($0) // "A" } To explain first() operator, I created an array which contains different elements and made it a publisher. When you use first() operator…
