About the test

The iOS and Swift online test assesses candidates' knowledge of the Swift programming language, mobile development concepts, and iOS APIs.

It's an ideal test for pre-employment screening. A good Swift iOS developer should be familiar with programming in Swift, mobile development concepts, and be able to use iOS APIs to create and maintain iOS applications.

This online test requires candidates to answer a number of multiple-choice questions about iOS code snippets and mobile development specifics, and to solve coding problems in Swift.

  • When the read method is called on the ReadableObject class, it returns the value that it received in the constructor.
  • The isReadable method returns true in the ReadableObject class. The isReadable method of the ReadOnceObject class should return true the first time it's called, and false every time after.

What others say

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
