The demand for custom-built and user-friendly mobile solutions has never been so high, however, all the customers and swift app developers face the same challenge – choosing the right tech stack for custom software development. Another challenge is the necessity to find the best app developers for hire. Modern programming languages allow Swift developers to build multi-featured native apps with excellent performance and unique designs. In this article, we will focus on the custom Swift app development and discuss the main benefits of Swift mobile app development for your business.

Swift developers – a short overlook in the historic progression

Custom native app development, unlike the cross-platform alternatives, allows the implementation of the 100% available features for the chosen operating system, performs much better, and allows Swift developers the creation of a platform-specific UI design with the native toolset. Native Swift app development allows creating a perfectly functioning user-friendly app, offering a unique experience and occupying the leading positions on the market. Thus, a business owner can increase the retention rate and customer’s loyalty.

The preferences and specificities of software development in the US are different in comparison to how other countries approach it. According to the latest report, Apple’s market share climbed three points, from 39% to 42% in the US in 2021. The loyalty to Apple devices is explained not only by the trends but also advanced Swift iOS development that becomes more stable and relevant occupying the leading positions over the years. According to the GitHub list of the most actively developed programming languages, Swift app development is among the top 5 most starred languages:

A brief historic overview of Swift app development language

  • The Swift 1.0 was announced by Apple in 2014 and it was fully compatible with Objective-C, and it was much faster, safer, and allowed Swift developers to write iOS and OS X Apps without writing additional code. It had a range of new features (variables, constants, type interface, generic classes etc.). The Playground feature allowed testing and rendering code in a real-time environment.
  • The Swift 2.0 was introduced as an open-source language and enabled Swift developers to make the debugging process safer and faster. The language became source-oriented, enabling developers to use protocols as interfaces, extended protocols, and specify methods.
  • The Swift 3.0 introduced in 2016 still required to add labels to all function parameters, enabled the Swift developers to keep the code more concise by removing the unnecessary words from function names, and simplified the import of C functions into the code by introducing new attributes for them. After some time, Apple has simplified the API guidelines to simplify the job for Swift app developers, allowing them to use verbs and nouns. 
  • Released in 2017, the Swift 4.0 introduced a transformation of built-in classes and structures. It allowed Swift developers to update the devious version of the language, using the migration functionality built into the Xcode.
  • In 2018, Swift surpassed the Objective-C.
  • In 2019, the Swift 5.0 was released. It allowed the Swift runtime to be incorporated into Apple operating system. It presented a stable binary interface on Apple platforms and backward compatibility.
  • The version 5.1, released in September of the same year, allowed the extension of stable features to compile-time with the introduction of module stability, allowing to create and share the binary frameworks for future versions.
  • The 5.5 version was officially released in 2021 and expanded the language support for concurrency and asynchronous code, introducing a unique version of the actor model.

Backed up by one of the most influential market leaders, Swift app development has become dominant for iOS native apps, opening unique possibilities for business growth. It speeds up the development process, cuts expenses, simplifies code maintenance, and guarantees the highest quality of code.

Why use Swift for mobile app development – real value for business 

Swift app development has many benefits, in comparison to its predecessor Objective-C: it combines performance, efficiency, simplicity, and interactivity. Let us dive deeper into what benefits Swift app development provides for business?

  • Speeds up the development process. Simplified syntax and grammar and the concise nature of the Swift application development language allow decreasing the amount of code needed to perform certain tasks. Automatic Reference Counting (ARC) tracks all the work and manages the memory usage, thus the app is taking less time for development. For example, Lyft, a driver-on-demand car service has completely rewritten the app using Swift. Their Swift developers claimed it was the best strategic move since it allowed them to shorten the codebase three times. It also allowed implementing the new on-boarding feature taking only one week and one engineer.

  • Easily scale product and team. Using Swift iOS development means getting a future-proof product and the ability to implement new features when needed. It is a long-term investment allowing also to scale the development team and hire a dedicated Swift developer, it enables the quick onboarding process, simplicity, and conciseness of the codebase. 
  • High performance, speed, and safety. Swift application development practices were built with the LLVM compiler framework, which transforms the language into code and optimizes it, speeding up the development process. A strong typing system and quick debugging minimizes the possibility of code crashes and allows Swift developers to instantly define and fix the code errors. It minimizes the risks of the deployment of low-quality code.
  • Decreased volume. The latest Swift version has all the basic libraries integrated, thus, the app built on those platforms will be smaller. Stable ABI (Application Binary Interface) allows Apple to support the language across all its platforms.
  • Easier memory management. It uses the Automated Reference Counting (a garbage collector function), which allows defining the instances which are no longer in use and deleting them. Thus, the app performance increases without lagging the memory.
  • Ability to use the language in front-end and back-end. Using Swift both on the backend and frontend allows extensive code sharing and reusing. The development process becomes faster, meaning fewer expenses on the development efforts.
  • It is an open-source programming language. It enables the coders to improve, enhance and modify in compliance with the specific business needs.

From the long-term perspective, the decision to choose Swift app development will mean the ability to benefit from modern, safe, and highly interactive technology. It means stability and relevance through time.

The top reasons why the future of app development belongs to custom app development in Swift

Progressive companies, striving to scale up, hire dedicated Swift developers since it allows building powerful and efficient iOS solutions faster and at fewer costs. The language is convenient and simple for the development team. Moreover, the Swift code is easy to maintain since the contents of the implementation and header files present a single file. It allows developers to focus on the very process of building an app instead of maintaining documents. Swift supports the dynamic libraries thus two different versions of the same app can match with ease. TIOBE Index for July 2021 has ranked Swift the 16th among the top 20 programming languages, and it has proved its position at a global scale.
