Why You Should Use This Swift Online Assessment Test

The Swift Online test helps recruiters and hiring managers to identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves expensive engineering time by filtering out unqualified candidates.

The idea behind this online Swift quiz is to help you assess on-the-job Swift concepts, Core Swift knowledge, coding, and debugging skills with just one test.

The Adaface Swift test screens candidates for the typical skills recruiters look for in a Swift developer:

  • Proficiency in Swift
  • OOPs fundamentals
  • Understanding of memory management and multi-threading
  • Experience with Swift in Xcode
  • Basic understanding of UI design

The insights generated from this assessment can be used by recruiters and hiring managers to identify the best candidates for the role. Anti-cheating features enable you to be comfortable with conducting assessments online. The Swift developer test is ideal for helping recruiters identify which candidates have the technical skills to do well on the job.

The Swift Online test is designed to test for Swift fundamentals and hands-on coding skills:

  • Swift fundamentals: These questions are designed to evaluate a candidate's knowledge and expertise of technical concepts in Swift -like OOPs, classes, data types, objects, variables, subclassing, UI kit, etc.
  • Coding skills: These questions are designed to assess a candidate's programming ability and debugging skills in Swift. In addition, these also test for problem-solving skills.

About Swift Developer Job Roles

Swift is a programming language developed by Apple that can be used to program applications for iOS, Mac, Apple TV, and Apple Watch. Swift is a friendly programming language for new coders and developers because it's quick, expressive, and enjoyable.

Swift 4 combines the best features of C and Objective-C while avoiding the limitations of C compatibility. When debugged properly, Swift produces faster code. It is compatible with both Apple and Linux platforms, making it safer and quicker. Memory is automatically controlled and is simple to use. This Swift Online Test for hiring candidates focuses on testing for on-the-job skills.

Typical Swift Developer responsibilities include:

  • Designing and developing high-volume, low-latency applications for iOS and OS X
  • Analyzing user requirements to inform application design
  • Defining application objectives and functionality
  • Monitor the applications' efficiency, consistency, and responsiveness
  • Collaborate with cross-functional teams to define, design, and ship new features
  • Supporting users by developing documentation and assistance tools

Distribution Of Test Scores

The actual score distribution will vary based on your candidate pipeline quality, but you should typically expect ~20% of the candidates to do well on Adaface assessments.

The score distribution for our assessments follow the normal curve. This is a good sign- standardized tests like SAT and GRE follow the normal distribution (bell curve).

Status quo assessments typically have the exact opposite of the bell curve (too many candidates getting close to 0, too many candidates getting close to 100 and too few candidates in the middle). This is typically because they focus on theoretical questions or trick questions, which are very binary in nature- either you know the trick/ theory or you don’t.

How Adaface Is Different

Adaface conversational assessments are reflective of on-the-job skills and see an 86% completion rate as compared to ~50% for traditional assessment platforms.

What is a custom assessment?

Every role is different and requires a custom assessment to identify top candidates efficiently. Adaface subject matter experts understand your job description/ role requirements and pick the most relevant questions from our library of 10000+ questions to create a technical assessment that helps you find the qualified candidates in your candidate pipeline quickly. All custom assessments are set up based on the job description, role requirements, must-have skills, experience level and salary range within a maximum of 48 hours and you will get an email notification once it goes live.

Check out a sample assessment here (no credit card required).

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.

How is Adaface different from other assessment tools?

We believe that status quo tech assessment platforms are not a fair way for companies to evaluate engineers because they focus on trick questions/ puzzles/ niche algorithms. We started Adaface to help companies find great engineers by assessing on-the-job skills required for a role. Read more about why we started Adaface.

Here's what's different with Adaface:

  • High quality non-googleable questions that test for on-the-job skills as opposed to theoretical knowledge.
  • A friendly conversational assessment with a chatbot, instead of sending a "test" to a candidate. This translates to a higher completion rate. Adaface assessments (86% candidate completion rate), as opposed to traditional tests (40-50% candidate completion rate)
  • Customized assessments for 700+ skills at different experience levels.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

  • Web proctoring
  • Webcam proctoring
  • Plagairism detection
  • Non-googleable questions
  • Secure browser

Read more about the proctoring features.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.

I'm a candidate. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

What is the cost of using this test?

You can check out our pricing plans.

Can I get a free trial?

The platform is completely self-serve, so here's one way to proceed:

  • You can sign up for free to get a feel for how it works.
  • The free trial includes one sample assessment (Java/ JavaScript) that you will find in your dashboard when you sign up. You can use it to review the quality of questions, and the candidate experience of a conversational test on Adaface.
  • To review the quality of questions, you can also review our public questions for 50+ skills here.
  • Once you're convinced that you want to try it out with real assessments and candidates, you can pick a plan according to your requirements.

I just moved to a paid plan. How can I request a custom assessment?
