Help/Support Got dummy DLL or something similar

[hikiasi 28 iPhone SE (2016) 14.6]

Hello everyone! Could anybody please tell me, for example with Unity games it is possible to get dummy DLL through armconverter with the help of which it will be possible to find functions and necessary offsets.
but how to do the same for applications, like for playing music, photoediting and others ? for example there is an application, I decrypted it with IGDecrypt and going into payload and looking at the folders I saw that apparently it is written in swift.
So, could you please tell me how to do all this not with a game, but with an application, to find the necessary functions and implement my changes ? I tried flex, but it says couldn't be processed
