Swift 5 Assessment Test

Swift is a programming language developed by Apple Inc. for iOS, iPadOS, macOS, watchOS, tvOS, and Linux. Swift is designed to work with Apple's Cocoa and Cocoa touch framework, and the existing objective- C code is written for Apple products. Swift 5 is a new version with features like ABI stability (the binary equivalent of an API) and Multiple(of:), which is used to check if an integer is a multiple of another integer.

Swift 5 assessment test helps tech recruiters and hiring managers to assess candidates' iOS Swift 5 programming skills. This test is designed by experienced subject matter experts (SMEs) to evaluate and hire iOS Swift developers per industry standards.


Swift 5 assessment test helps to screen the candidates who possess traits as follows: 



  • Ability to work with Swift 5 functions like assert statement, struct definition, return value, string manipulation, etc.
  • Understanding of code comprehension and working with the ABI feature
  • Proficient in Swift programming language with good knowledge of its ecosystem
  • Strong understanding of iOS SDK, Cocoa Touch framework

Swift 5 allows to write functions (methods) with parameters. Examine the following s function:

func s (for x : Int) -> Int {
return x <= 1 ? 1 : x * s (for : x - 2)

How do you call it to calculate s of 4 and store it in an immutable variable a? What is the value stored in a?


  • let a = s (4) // 24 is stored in a
  • let a = s (x: 4) // 12 is stored in a
  • let a = s (for: 4) // 8 is stored in a
  • let a = s (_: 4) // 16 is stored in a
  • There is an error in function square because you may not define for: as a parameter. You need to put _ instead of it.
