.obj file around 12 MB does not load

I am trying to load a obj file from the app's document directory.

Code Block let url = self.dir!.appendingPathComponent("3Dscan.obj")
let asset = MDLAsset(url: url)
scene =  SCNScene(mdlAsset: asset)


This works fine for smaller .obj files. But when I have large files (around 12MB) I get the error "Cannot load OBJ file"

I need to be able to load large files on the app, is there a work around?
