# Isogram

Determine if a word or phrase is an isogram.

An isogram (also known as a "nonpattern word") is a word or phrase without a repeating letter.

Examples of isograms:

- lumberjacks
- background
- downstream

The word *isograms*, however, is not an isogram, because the s repeats.

## 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 <path_to_exercism_dir>/objective-c/bob/Bob.m`.
