Sum Of Multiples
Given a number, find the sum of all the unique multiples of particular numbers up to but not including that number.
If we list all the natural numbers below 20 that are multiples of 3 or 5, we get 3, 5, 6, 9, 10, 12, 15, and 18.
The sum of these multiples is 78.
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
objcas a test runner utility.
Both are described in more detail here: http://exercism.io/languages/objective-c
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:
exercism submit <path-to-exercism-workspace>/objective-c/sum-of-multiples/SumOfMultiples.m
You can find the Exercism workspace by running
exercism debug and looking for the line beginning

Submitting Incomplete Solutions
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
