Bad example - you should use the example between NeXTSTEP/Mach and OS X, which the identical technology, library versioning, is used. (People do you still remember that OS X derived from NeXTSTEP, to the extent that OS X 10.0 have version number 4.0, picking up where NeXTSTEP left off, and this still count till now like OS X 10.9 = NeXTSTEP 13?)
Also, there is no need of “compatibility mode” as library versioning will allow that with a framework like this UIKit.framework/ + UIKit -> Versions/Current/UIKit + Headers -> Versions/Current/Herders + Resources -> Versions/Current/Resources + Versions/ ++ A/ +++ UIKit +++ Headers/ +++ Resources/ ++ B/ +++ UIKit +++ Headers/ +++ Resources/ ++ Current -> B The version A of UIKit library is what is shipped in iOS 6 (and before), almost as-is. Version B is iOS 7 UIKit that have all the new bells and whistles. The UIAlertView is somewhat special because it is not implemented in UIKit actually, instead they are in SpringBoard.app which is a native iOS 7 app. SpringBoard.app is (was, after some touch handling code got split into backboardd) Finder.app and WindowServer rolled into one package.
