Iphone password Fakescreen (very simple and easy)

This project is an idea to a magic app trick...
So, imagine that the app simulates the lock screen of the iphone (a screenshot of the real lockscreen). I try to enter the password for the first time and it's an error. Try for the second time and it's an error again..




. Then, when I try for the third time, the screen "unlocks" (showing the fake home screen,) and then the app "force quit" (so, the screen just blink and the app is no long running) showing the real home screen... (The number of attempts can be customized)...

A small detail: all password written it the app is transmitted to apple watch instantly, so i know exactly  what numbers the person is typing...

Another detail: Maybe apple doesn’t allow to publish it because of the copyright terms of using the lockscreen, correct?
So, I thought in a solution for that...
Let's take, for example, a existing an app that has a "fake calculator", for you to simulate the apple calc... But the calculator is very poor designed (just the numbers and some squares, like done in paint brush for windows LOL)... So, the app is native like this, but you can replace the screen for a screenshot of any photo, in this case, the screenshot of the real apple calculator... So, the app runs perfectly without copyrights issues...
