Can you rename the methods so that they follow the Swift 3 API design guidelines?

For example, the shuffle() method on immutable collections should be renamed to shuffled(). All the Reusable Formatters should be shared instead of sharedInstance. String.isNumber() should be a computed property instead of a method.

I fully agree with you! The migration to Swift 3 is a real pain since there's so much things to change 😬
