What is Swift?

What is Swift?

Swift is a programming language launched in 2014. It is used for all purposes and to create innovative software designs for iOS, macOS, and watchOS. It is run on the Linux and Windows operating systems. Swift is famous for its concise learning and elimination of redundant procedures found in the preceding language, Objective C. This implies that Swift will continue to be utilized for various web services and apps. 

Why Swift for Software Development?

Apple’s powerful and user-friendly Swift programming language has completely transformed app development for iOS, macOS, watchOS, and tvOS. Many developers worldwide consider it for its strength, versatility, and ease of use. Because of its clear and expressive syntax, Swift code is swift, efficient, enjoyable, and interactive. 

Here are some of the outstanding features that Swift offers for your consideration; you will be sure to choose Swift for your development project:

  1. Objective-C Runtime Library: Swift effortlessly combines with the Objective-C runtime library, enabling the harmonic coexistence of C, Objective-C, C++, and Swift code within a single program.
  2. Open-Source: Swift is compatible with web design and implementation on other platforms, extending its reach beyond Apple products as an open-source language.
  3. Generics: Swift’s generics allow programmers to design reusable, adaptable functions and types that work with any data, increasing the adaptability of their code.
  4. Native Error Handling: Swift has robust error-handling functionality, allowing programmers to intercept, handle, spread, and modify errors in real-time.
  5. Package Manager: Swift streamlines the development process by making it easier to create, test, and package Swift libraries and executables across platforms.
  6. Troubleshooting and Debugging: The LLDB debugger allows developers to use REPL and integrated debugging tools for precise and quick troubleshooting.
  7. Compatibility: Swift’s most recent version ensures binary app compatibility, removing the need to recompile code with each operating system release.
  8. Memory Management and Safety: Automatic Reference Counting (ARC) is a feature of Swift that helps with automatic memory management, reducing typical memory-related problems and improving code safety.

Swift provides several more helpful functionalities besides these fundamental elements, like configurable enumerations that support pattern matching and payloads, Closure syntax for optimization, and Tuples for value groups.

Factors to Consider Before Hire Swift Developers

Prior to initiating the hiring process, it’s crucial to consider a few key elements. This not only impacts the hiring procedure but also the value of the new hires, underlining the significance of your role in the company’s operations. Listed below are a few things to consider before hiring iOS app developers.

  • Portfolio relevance: By reviewing their portfolio, you can gain insights into the apps and software they have produced. This can help you identify candidates whose work is impressive and relevant to the niche for which your company develops apps, instilling a sense of hope and optimism about the candidates’ potential.
  • Communication: Companies now hire workers from a distance, frequently resulting in a linguistic barrier among team members. Determine whether the possible employee is comfortable communicating in your language.
  • Verify the work: At least three fully functional apps should be included in the portfolio they submit. You should assess their coding abilities in this manner.
  • Work quality: No company wants to release sluggish, malfunctioning applications. Examine each submission in the portfolio to gauge its quality. Call each of the provided numbers to ensure the references on the résumé are legitimate.
  • Promptness: If candidates take too long to answer calls and emails, they may continue to do so even after being hired. If this occurs too frequently, it’s preferable to back off.
  • Request assistance: Make sure a professional developer occupies the interview board. This will help you hire mobile app developers to build swift applicants by enabling you to evaluate the sample code requests and other coding assessments more fairly.
