Inside this iOS Developer Hiring Test

The iOS Online Test is a pre-employment screening test to gauge the depth and breadth of a candidate's knowledge of the Swift programming language, including its concepts and applications. The test provides a data-driven way to test if candidates are skilled in iOS Swift, highlighting each individual's strengths and areas requiring improvement. This implies that hiring managers and recruiting teams can make a more informed profile of candidates and get guidance on which applicants to proceed with and which ones to disregard. 

This test is 60 minutes long and contains 19 questions (18 MCQ+ 1 coding question) that aim to understand an applicant's conceptual and functional understanding of iOS and Swift. The test, designed and validated by seasoned subject matter experts, offers a well-rounded review of the test-taker's skills, competencies, on-the-job skills, and work readiness. Tech recruiters widely use the iOS Developer Hiring Test before the interview process to assess individuals for the specific skills they seek in a skilled iOS developer with experience ranging from 0 to 2 years.

From a well-structured set of questions that focus on critical skills required to be an iOS programmer, recruiters will be able to identify top tech talent with a profound understanding of developing mobile apps on the iOS ecosystem and writing optimized codes in Swift.

The iOS Online Test helps to screen candidates for the following roles: 

  • iOS Swift developer 
  • Junior Swift developer 
  • Software developer (Swift)


With the skyrocketing growth in the number of mobile device users, one can observe the rapid expansion of the global mobile app software market. Inarguably, seasoned and dedicated developers play a pivotal role in meeting the burgeoning demand for mobile applications. Even though nowadays, mobile app developers have so many programming languages to choose from, Swift has become increasingly popular among developers working with iOS operating systems. Undoubtedly for an app to hit the App Store, one needs the support and expertise of skilled Swift developers.

Finding the best iOS (Swift) developers will enable businesses to achieve the desired business outcomes. Expert Swift developers are instrumental in improving productivity, facilitating innovative idea-generation sessions, and enhancing business outcomes. Moreover, they are experienced in using programming language to create optimal iOS apps with great functional design, efficient code development, and unmatched security and scalability.

Despite their importance, finding an iOS developer proficient in building robust, bug and crash-proof apps can take a lot of work. Likewise, hiring suitable candidates for available roles seems challenging with a subpar and half-baked technical evaluation and screening process. That is where the part of pre-employment tests comes into play. These tests are a surefire way of determining someone's true potential by predicting their job performance and future work behavior based on data.

The iOS Developer Hiring Test is intended for the same purpose, enabling recruiters to gain insights into an applicant's work readiness and on-the-job skills. The test helps filter out unqualified candidates and puts the spotlight on candidates with the proper knowledge, expertise, and experience for the desired openings.

Administering an iOS Online Test during the screening process also enables hiring experts to understand whether a given candidate with a decorated resume and glorious accomplishments has the skills that align with the role's requirements, helping them decide whether to bring that candidate in for interviews. Undoubtedly, this iOS Developer Assessment can help determine which test-taker's skills fit the role based on their test performance and help make informed hiring decisions.
