title: Why Cocoa design patterns not representing best practices on Apple documentation anymore?
body: <p>I just would like to know why from the official documentation of Apple, the common cocoa design patterns used doesn't represent the best practices to develop apps.</p>
  
  <p>From <a href="https://developer.apple.com/legacy/library/documentation/Cocoa/Conceptual/CocoaFundamentals/CocoaDesignPatterns/CocoaDesignPatterns.html#//apple_ref/doc/uid/TP40002974-CH6-SW25" rel="nofollow noreferrer">https://developer.apple.com/legacy/library/documentation/Cocoa/Conceptual/CocoaFundamentals/CocoaDesignPatterns/CocoaDesignPatterns.html#//apple_ref/doc/uid/TP40002974-CH6-SW25</a></p>
