This new `OptionSet` will automatically work with your enum to create a distinct set of values. Additionally it will decode and encode your values as an Array of String. This means the value: + +```swift +[.aim, .delicious, .googleplus, .windowslive] +``` + +is encoded as: + +```json +["aim", "delicious", "googleplus", "windowslive"] +``` + +# Further Code Documentation + +[Documentation Here](https://swiftpackageindex.com/brightdigit/Options/main/documentation/options) + +# License + +This code is distributed under the MIT license.
