Dr. Dominik Hauser

Dr. Dominik Hauser is an iOS developer working for a small company in western Germany. In over 11 years as an iOS developer, he has worked on many different apps, both large and small. In his spare time, Dominik builds small (often silly) apps and explores how he can become a better iOS developer. He talks at conferences, writes books, and is active in the iOS community in general. His most successful open source component (in terms of stars) is a pull-to-refresh control for a table view that consists of an actual SpriteKit game. Before Dominik became an iOS developer, he was a physicist, researching the most powerful photon sources within our galaxy.

These tests could be added to ToDoItemTests, but they are easier to maintain when the test classes mirror the implementation classes/structs. So, we need a new test case class.

Open the Project navigator, select the ToDoTests group, and add a unit test case class called LocationTests. Make sure that you go to iOS | Source | Unit Test Case Class since we want to test the iOS code, and Xcode sometimes navigates to OS X | Source.

Set up the editor to show LocationTests.swift on the left-hand side and Location.swift in the Assistant Editor on the right-hand side. In the test class, add @testable import ToDo and remove the testExample() and testPerformanceExample() template tests.

The location of a to-do item will be used in the app to show...
