About the test

The Swift online test assesses candidates' knowledge of programming in the Swift language and their ability to leverage commonly used parts of its standard library.

It's an ideal test for pre-employment screening. A good Swift developer needs to be able not only to solve problems using Swift but also be familiar with Swift’s native data structures and language constructs.

This online test requires candidates to solve coding problems in Swift and answer multiple choice questions about Swift code.

Sample public questions

3 min

Consider the following Swift definition of the structure Car:

struct Car {
    var color:UIColor?
    let model:String
    init(model:String) {
        self.model = model
        self.color = nil

    mutating func changeColor(color:UIColor) {
        self.color = color

Select the statements that are correct.

5 min
Memory Management

An application uses the User and Subscription classes for tracking all subscriptions that a user has purchased. Currently, the memory occupied by instances of those classes is never reclaimed.

Without changing the public API, fix the memory leak.

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.
