OrderedDictionary is a lightweight implementation of an ordered dictionary data structure in Swift.

The OrderedDictionary struct is a generic collection which combines the features of Dictionary and Array from the Swift standard library. Like Dictionary it stores key-value pairs with each key being unique and maps each key to an associated value. Like Array it stores those pairs sorted and accessible by a zero-based integer index.

OrderedDictionary provides similar APIs like collections in the Swift standard library. This includes accessing contents by keys or indices, inserting and removing elements, iterating, sorting etc.

Internally OrderedDictionary uses a backing store composed of an instance of Dictionary for storing the key-value pairs and an instance of Array for managing the ordered keys. This means it is not the most performant implementation possible, but it gets its job done by reusing most functionality from the Swift standard library.

• Swift 4

This library is distributed as a Swift framework and can be integrated into your project in following ways:

The easiest way is to use the package manager Carthage.

1. Add github "lukaskubanek/OrderedDictionary" to your Cartfile.
2. Run carthage bootstrap.
3. Drag either the OrderedDictionary.xcodeproj or the OrderedDictionary.framework into your project/workspace and link your target against the OrderedDictionary.framework.
4. Make sure the framework gets copied to your application bundle.
5. Import the framework using import OrderedDictionary.

Another option is to use Git submodules and integrating the Xcode project OrderedDictionary.xcodeproj directly to your Xcode workspace.

For the usage of this library please refer to the example playground. For documentation please refer to the documentation comments.

The changelog is managed on the GitHub releases page.
