How to Approach Wrappers for Swift Properties
A property wrapper is a generic structure that encapsulates read and write access to the property and adds additional behavior to it.

In this article, Toptal Freelance iOS Developer Alexander Gaidukov demonstrates Swift 5.1’s new @propertyWrapper annotation—a more elegant solution.
