Question Native iOS Mesh capture with texture

Hi All,

I am working on native iOS app and exploring AR capability , here we are captured mesh of evironment and created 3D model. However the 3D model in native is always white without texture as real environment,
We want to achieve this into native iPhone and iPad applications .

Any way we could achieve this?. Is it possible integrating Unity framework in Native iOS app

Please suggest how we can resolve this. Thanks in Advance.
