# Gigasecond Calculate the moment when someone has lived for 10^9 seconds. A gigasecond is 10^9 (1,000,000,000) seconds. ## Setup There are two different methods of getting set up to run the tests with Objective-C: - Create an Xcode project with a test target which will run the tests. - Use the ruby gem `objc` as a test runner utility. Both are described in more detail here: http://exercism.io/languages/objective-c ### Submitting Exercises When submitting an exercise, make sure your solution file is in the same directory as the test code. The submit command will look something like: ```shell exercism submit /objective-c/gigasecond/Gigasecond.m ``` You can find the Exercism workspace by running `exercism debug` and looking for the line beginning with Workspace. ## Source Chapter 9 in Chris Pine's online Learn to Program tutorial.
