Property Observers and Wrappers

Efficiently handling state changes and promoting code reusability are key to building efficient and reliable applications. In Swift, two powerful features that help with these tasks are property observers and property wrappers, which provide effective ways to monitor changes in property values and adjust behaviors.

Property observers enable our applications to keep track of property modifications and react accordingly. They provide a simple and effective way to execute custom actions when the value of a property changes. They enable applications to automatically respond to these changes, ensuring that any necessary updates or validations are performed. Property wrappers, on the other hand, bundle the logic ...
