# Nth Prime Given a number n, determine what the nth prime is. By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6th prime is 13. If your language provides methods in the standard library to deal with prime numbers, pretend they don't exist and implement them yourself. ## 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. For example, if you're submitting `Bob.m` for the Bob exercise, the submit command would be something like `exercism submit /objective-c/bob/Bob.m`. ## Source A variation on Problem 7 at Project Euler [http://projecteuler.net/problem=7](http://projecteuler.net/problem=7) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
