Swift is an intuitive, easy-to-use, and robust programming language. Although it’s a general-purpose language, it was created by Apple – so it’s mostly used for Mac, iOS, Apple Watch, and Apple TV software development. However, the newer versions are also compatible with Linux. And seeing as Swift is an open-source language, anyone can use it to create Apple-compatible software.
If you have an idea for an iPhone app, Swift is really the only language (apart from the dated Objective-C) that will seamlessly fit with iOS. And seeing as Apple claims that Objective-C is over 2.5 slower than Swift, it’s really a no-brainer.
Today’s iOS developers all use Swift – and seeing as mobile phones and tablets are the two devices people use for Internet access the most, knowing the programming language for the most popular smartphone on the planet is vital.
Swift is also a premier choice for Mac-compatible desktop apps. Of course, you’ve got a wider array of options there, because MacOS applications can also be written in general-purpose languages.
Apple Watches are also in high demand these days, and Swift is the language almost all app developers use while creating software for Apple Watches. The same goes for apps on Apple’s tvOS, the OS powerhouse behind Apple TVs.
The length of a project depends on many factors, including the scope of your project and the technical complexity of it.

We suggest chatting with the interested developers to ensure both sides are on the same page. For more information on how to post a freelance Swift request on Codementor, check out our article.
We don’t charge anything when you post a freelance hiring request for Swift developers! You’ll have the chance to determine what the budget for your project is when you post the request. You’ll only need to pay the developer if you’re 100% satisfied with their work. Please know that Codementor charges a small service fee when a developer completes the job.
So, Swift programmers usually work on software for various Apple products. Obviously, they’re proficient in Apple’s Swift language. But, beyond that, if you’re looking for programmers with some serious experience under their belt – you can also look for people who have worked in Objective-C before that.
On a daily basis, freelance Swift developers develop and maintain OS X and iOS applications and integrate them with various back-end services. To achieve that, Swift coders need to have a working knowledge of Swift’s characteristics and performance limits. They should also have some experience with RESTful APIs for back-end connections and an understanding of UI design principles.
Apart from that, a decent Swift programmer will know the basics of object-oriented programming in general, and the interface guidelines and design principles for Apple-focused software. In terms of soft skills, they should be problem-solvers, critical thinkers, and possess decent communication and interpersonal skills.
We do a comprehensive technical and communications screen of all Swift developers at Codementor. Our network includes book authors, popular open source contributors, top Stack Overflow users and engineers at top tech companies. In addition, to continually ensure the quality of our freelancers, we regularly check in on existing Swift developers’ user satisfaction rates.
The best way to see whether a Swift developer knows their stuff is to present them with a few code snippets and ask them whether something needs to be fixed in them. And if not – ask them if they have any ideas for further improving or optimizing the code.
Beyond that, here are a few other interview questions for freelance Swift developers:
