swift – iOS app default sample is MVC, why want to revamp mvc once more?

The construction of UIKit apps relies on the Mannequin-View-Controller (MVC) design sample, whereby objects are divided by their goal. Mannequin objects handle the app’s information and enterprise logic. View objects present a visible illustration of your information. Controller objects act as a bridge between your mannequin and consider objects, transferring information between them at applicable instances. However once we make an unlimited software/challenge, we set up/create the mannequin, view, and controller group once more and likewise create a respective file there. I consider it would improve the coding effectivity and make cleansing the challenge structure/enterprise extra impede. However I want particulars and clear-cut solutions one thing extra of this. Really, why can we recreate/redesign MVC once more? Thanks upfront.
