Using Material Design on iOS

I have an Android app developed by using Material Design principles. Currently, I am planning to release it on iOS too.

I read several blogs/SO posts, which state that Apple is strict about Flat Design and UI consistency on their platform, but I see that, most Google apps look exactly the same on iOS as their Android variant and follow Android's design language. Why are they allowed then? Moreover, Google has published Material Components for iOS.

I am wondering that, is it okay if I implement the exact similar Android UI for iOS? Has Apple tweaked some of their rules to allow Material design on iOS?
