Use of Swift test

The Swift test is helpful for testing programming skills in the Swift language, developed by Apple to code iOS applications. It assesses the candidate’s knowledge of the basics and working with Swift, OOPs concepts, data types, and sorting functions.

The recruitment assessment test for the iOS programming language Swift evaluates the candidate’s ability to code with Swift and their general awareness of how the language works. It gauges the test taker’s aptitude for concepts exclusive to Swift, such as Collection Types, Tuples, Optionals, Protocols, Properties, and Key Paths. The test also assesses how candidates convert logic into executable code and their capacity to interpret code snippets & guess their output accurately.

The Swift recruitment test is beneficial for hiring an efficient programmer who possesses adequate knowledge of the Swift programming language and knows how to use it for creating functional mobile & web applications. It can be used to identify individuals with hands-on experience using Swift and the ability to think critically, understanding end-to-end requirements before writing codes.

This Swift test can be used to evaluate the candidate’s technical knowledge required for the job roles: Swift Developers, Senior iOS Developers, iOS Swift Developers, iOS Lead, etc. Owing to the robust framework of Swift, individuals with appropriate skills and practical coding experience using this language can help the software development process to run smoothly and successfully. This recruitment assessment helps identify such skilled developers who can create applications in suitable IDEs for platforms like iOS, macOS, Linux, and z/OS.

Customer satisfaction

Testlify helps you identify the best talent from anywhere in the world, with a seamless experience that candidates and hiring teams love every step of the way.

1

Working with Swift

Candidates are tested on how well-versed they are with the Swift language’s syntax, execution, and programming environment. The assessment gauges them on what working with Swift would entail, its coding complexities, and nuances.

2

OOPs concepts

The Swift language supports Object Oriented Programming. This test assesses the candidates on basic OOPs concepts like encapsulation, inheritance, and polymorphism. The test taker’s aptitude for classes, properties, methods, subscripts, initialization, and deinitialization is also gauged

3

Scala Basics

Understanding Scala's foundational concepts is crucial for Swift developers. This sub-skill evaluates familiarity with data types, variables, operators, and control structures in Scala. Proficiency in Scala enhances a developer's ability to write concise, functional code and facilitates a seamless transition between Swift and Scala. Assessing this skill ensures candidates possess a solid foundation, leading to adaptable and skilled developers capable of effectively collaborating on projects involving both languages.

4

Data Types

The knowledge that the candidate has about data types supported by Swift, viz. Int, String, Float, Double Float, Boolean, Characters, etc., are evaluated in the Swift assessment test. Their knack for applying different data types to write a working code is analyzed using questions about its concepts in this assessment.

5

Sorting

Sorting is one of the basic but essential functionalities used while programming with any language. Swift’s sorting function, the Big O Notation, the different sorting algorithms such as Bubble sort, Insertion sort, Selection sort, Merge sort, and Quick sort, and how they work are analyzed in this assessment.

6

Basics

The test taker’s aptitude to understand basic Swift codes and assess their outcomes is measured. Code snippets comprising a function that utilizes the fundamental concepts of the language are used to evaluate the candidate’s coding knowledge using Swift.
