Selective Equality Checking in Swift

This gist vends a new protocol called SelectiveEquatable which contains a single method, isEqual(to:by:). This method allows you to check the equality of two values by selectively picking which properties you would like to compare.

SelectiveEquatable is also available as a Swift Package!

Background

To see my thought process of how and why I created this, check out my blog post: Selective Equality Checking in Swift.
