Needs is a small library that let you use a property wrapper to automatically call setNeeds- methods.
It works out-of-the-box for all setNeeds- methods available on UIView, UIViewController and NSView.
If you need to you can also extend it with your own Need.

Needs is available through CocoaPods and SwiftPM
Add a Needs property wrapper to one of your properties to call automatically the desired setNeeds- method
