How DevSkiller Swift 4 interview questions work

The unique aspect to focus on here is the RealLifeTesting™ methodology. Our Swift 4 interview questions use technology designed to replicate a Swift developer’s actual work-environment and challenges are set for them based on that simulation. This means that the results are extremely accurate to real life, meaning recruiters can gain far more insight on their candidates than with traditional algorithm tests or interviews alone.

DevSkiller Swift 4 online tests allow you to assess knowledge of Swift 4, coding ability, problem-solving and time-management skills, all during the initial stage of recruitment.

What to know about Swift 4

First launched in 2014, Swift was developed by Apple as a replacement for C, C++, and Objective-C. The intention was for Swift to be easier to use than the previous C languages, with less room for error. Swift is very versatile. It can be used for desktop, mobile, and cloud applications. Most famously its technology was used for the creation of leading language app ‘Duolingo’ with the application being written in Swift.

DevSkiller’s Swift 4 interview questions can help you identify the exact qualities to look for in a Swift 4 developer.

Want proof that our Swift 4 online tests work?

Investing in our screening tool can be a big responsibility. You will want to be sure. So don’t take our word for it, check out the following case study of one of our previous clients, ImpacTech.


ImpacTech develops Business Intelligence solutions using Artificial intelligence. Before turning to DevSkiller, ImpacTech’s recruitment process was entirely offline. This made it very difficult to evaluate a candidate’s skills based on interviews alone, not to mention being time-consuming.

More interviews than were needed had to be carried out making the whole process labored and inefficient.

DevSkiller helped to automate ImpacTech’s evaluation process and with testing taking place online, ImpacTech were able to cut down on the amount of candidates who were invited in for interviews. Before implementing DevSkiller, 198 interviews were carried out to make only 28 hires. DevSkiller managed to reduce the number of candidates that made it through to the interview stage by 83%. Meaning that only those most qualified were selected for interviews. The countless hours of time and effort saved helped ImpacTech revolutionize their whole recruitment procedure.

Ivana Nikolic HR Manager bij ImpacTech

"Na de overstap naar DevSkiller worden niet-levensvatbare kandidaten nu veel eerder in het wervingsproces geëlimineerd, waardoor we kostbare tijd besparen. Daarnaast heeft de automatische evaluatie door DevSkiller zelf ook tijd bespaard"

Vaak gestelde vragen

Wat is RealLifeTestingTM?

RealLifeTestingTM is at the heart of all DevSkiller Swift 4 testing. Most traditional developer tests use algorithmic puzzles that only really serve to test a developer’s memory of old coding patterns and algorithms, and don’t accurately reflect the work a developer actually does. RealLifeTestingTM is changing that. It simulates the real-world scenarios developers are likely to encounter in their everyday work. This allows recruiters to observe how each candidate will actually cope in the role and provides recruiters with a comprehensive understanding of each applicant’s level of skill.

Successful candidates are those that can demonstrate a clear understanding and knowledge of Swift 4 and can utilize resources like Stack Overflow. They need to possess the critical thinking needed to determine the quickest and most efficient solutions to the problems they encounter.

Hoe lang duurt het om DevSkiller op te zetten?

From the start, DevSkiller testing is designed to be time-efficient. It is easy to set-up and takes no time at all to get started sending out your Swift 4 test invites. DevSkiller provides an extensive catalogue of ready-to-go tests, meaning you can start testing your candidates as soon as your account is set up.

Hoe maken kandidaten een test?

The first advantage of DevSkiller’s Swift 4 online tests, is they are carried out remotely. This is a huge time-saver for recruiters. Your initial screening stage is as simple as sending out emails with test invites attached. The second advantage is that evaluation of these tests is automated, meaning you can just sit back and wait for the results.

For the candidates the process is very simple. They receive their test invite and can start at any time and from anywhere. They have the option to use our state of the art in-browser IDE, or to complete the project on their favorite IDE and then clone to GIT. They can run unit tests to ensure their solutions are working the way they’re supposed to much like in their real work. Either they will complete the test or the time will elapse, in any case the results will then be automatically sent for evaluation and a report on how they did will be produced and sent to the recruiter. Our DevSkiller Swift 4 online testing really couldn’t be simpler.
