Introducing Swift, the programming language that kicked off the revolution in iOS app development. Its straight forward syntax, high performance, and multiple libraries have turned it into the programming language of choice for numerous developers who look to develop efficient and safe apps.

Swift: the history & evolution

Apple Inc. faced this in June 2014, when they unleashed Swiftlang to the world. yowestogel Swiftlangaimed to improve upon the limitations of Objective-C and offer a more contemporary, efficient language for iOS and macOS development. It aimed in making the programming language more easy to learn, safe to use, and having the code written faster. Swift had been influenced by a number of existing programming languages, among them Objective-C, Rust, Haskell and Python.

It was created to be readable, concise, and expressive which also makes it effective for developers both new and experienced to rap their head around this quick. Swift has evolved since its launch; a number of updates and improvements have been introduced in every subsequent version and here is a brief summary of some of the newly added features.

Benefits of Coding with Swift

Swift has a number of benefits that separate it from other programming languages, which is why developers rely on it. Speed and performance are among the primary benefits. Swiftlang has been designed to have faster code execution and app loading times as well. The super fast compiler of C++ gives developers high performing apps and It optimizes the code for a better performance. Strong type inference is another benefit of using Swiftlang.

In Swiftlang, you do not have to declare type of variable explicitly. The type can be automatically inferred by the compiler, given its initial value The aim of this feature was twofold — decreasing code verbosity and identifying type-related errors early on in the development process. Swift is also amazing at memory management. It is an Object Oriented Language which use Automatic Reference Counting (ARC) which automatically deallocate object when they are no longer used. This means developers never needs to manage memory manually and expiration can nevere app and crashing.

Syntax and Fundamentals of Swiftlang

99 Swift Have a very clear and expressive syntax Swift is easy to read and write. The syntax is intended to be more readable, concise, and natural like English which enables the developers to do coding in an easier and most readable way. They are going for a mix of static and dynamic typing, trying to hit the sweet spot between flexibility and power. Swift has short and clear syntax, for example, variables are declared using the var keyword and constants using let.

var variables can be changed, while those declared with let are constant. Optional types are a type that may have a value but could also have no value, and Swiftlang has also support for optional types. At the same time it also solves identifying the cases in one place, when a value can be missing. Swiftlang also includes control flow statements, such as if, for, and switch, that you will encounter in this chapter. They provide a method of changing the order of execution of code based on a condition.

Combining higher-order functions and closures allows developers to write fewer and more expressive code, one of the benefits of functional programming paradigms, which Swift supports as well.

OOP in Swift

Well, Swift is a multi-paradigm language so we can work around OOP principles. Developer using this language can also define classes, structures, and enumerations to encapsulate data and behavior. When it comes to building complex and reusable code, classes in Swift are great because they can do some really good stuff that includes inheritance, polymorphism, encapsulation. Apart from classes, Swift also brings the concept of structures.

A structure is a value type that can have properties and methods like classes. An instance of a structure is copied by assignment or as an argument to a method, contrasting with a class, whose instance is not. Swift also has the power of enumerations, or enums for short. Using them, developers define a set of related values and bind them with a type. The same could apply to methods or properties — in which case, an enum is superior to a protocol.

A comparison Swiftlang vs. Objective-C

Swift only became a reality to’s develop iOS and macOS applications in 2014 and before then, Objective-C was the default language for the same goals. However, due to number of advantages like modern verbosity and performance improvement in the new language, Swiftlang has gained popularity and is used by number of projects. Its syntax is also one of the major differences from the Objective-C. Compared to the verbose syntax of Objective-C, Swift has a more concise and expressive syntax.

In addition, Swiftlang syntax is easier to read and understand making it beginner-friendly as well. Swift provides some of the functionality, that is not supported in Objective-C, like optionals, generics, and type inference. These capabilities make Swiftlang code more secure and faster than the code writing stage of development. Swift also has better interoperability with Objective-C.

One of these languages is Swift, which has been designed to work alongside Objective-C and which also means that an iOS application can be written in both languages within the same project. Integrating with Objective-C. — By the end of this article, you will see how powerful Swiftlang is with Objective-C interoperability. This makes it painless when needing to migrate existing Objective-C code to Swift and use the massive ecosystem of Objective-C libraries and frameworks.

Now it also comes with a rich ecosystem of frameworks and libraries to help the developers in building powerful and feature-rich applications. Here are some popular frameworks: UIKit: A framework that provides the functionality for building sekilas application for iOS or macOS_flat. This includes classes for input, reading and so forth. WHAT: —Core Data is a framework that you use to manage the model layer object in your application—WHAT who delete my app data.

As the name implies, it provides a handy and effective way to store, retrieve, and query data for developers. Alamofire: — Alamofire is an elegant networking library written in Swiftlang. If you’re still wish to integrate the lower-level API, Requests does provide a simple HTTP API for common requests, a simple and elegant interface.

Alamofire is an HTTP networking library written in Swift with the aim of simplifying common networking tasks and improving code readability. Realm Realm is a database developed for mobile applications, with the standard of working faster and in a scalable way. Provides a clean and human readable API for modifying objects (including real-time change listeners with appstate).

Swift coding best practices

When it comes to writing clean and maintainable code in Swiftlang, there are certain best practices to follow. Follow Bellow steps to improve your swift code:- Describe your variable and function names: Giving proper name to your variables and functions help in understanding the code more better and any others who see your code. Using Correct Naming Convention in Swift – Swift has certain standards for how the naming should be of variables, functions and types. Adhering to conventions like these means that we have some common grounds between all of us, making it easier for other people to read the code.

Do not use forced unwrapping: Forced unwrapping of an optional using the exclamation mark (! value crashes at run time (i.e. if the value is nil) Instead, you should take care of optionals safely, as in optional binding or optional chaining. When value types make sense, use them: Swift has value types in the form of structures and enums. Apply them only when necessary to minimize the likelihood of adverse reactions and optimize performance.

Short small focused functions: If have complex function, create a new functions for this. This makes code clearly to read and we can also make our code testable and debuggale much easier. Commenting and Documentation — Commenting your code and documenting how to run it makes it easier for others to follow along with what you have done. It also simplifies your task of going back to your code and understanding it in the future.
