Exercise - iOS Code Style

Overview:

Practice writing and refactoring clean code with good style

Getting Started:

Clone this repository to create a local copy on your computer

git clone https://github.com/IntrepidPursuits/code-style-exercise-ios.git

Create a branch called <your-name>/clean-code
```
git checkout -b <your-name>/clean-code
```

The App:

The app uses a UICollectionView to display a randomized color palette. When a colored square is tapped, its hex value appears in either black or white depending on the lightness or darkness of the color. When the "Generate New Colors" button is tapped, the palette refreshes and displays the user-defined number of colored squares. If no value is specified, it defaults to 12 squares.

Your Task:

Go through the code provided and fix any style issues you find. The fixes for the problems can range from small (e.g. spacing) to large (e.g. completely refactor the logic flow). Remember that we're aiming for clarity over brevity. If you need help, refer to the Intrepid Swift Style Guide.

When You're Done:

Push your branch up to Github
```
git push origin <your-name>/clean-code
```
Create a pull request on Github and fix any issues found in code review
