Loading a .scnz file in Xcode / Displaying it in a view using Swift

Hello!

I need to display a .scnz 3D model in an iOS app. I tried converting the file to a .scn file so I could use it with SCNScene but the file became corrupted.

I also tried to instantiate a SCNScene with the .scnz file but that didn't work either (crash when instantiating it).

After all this, what would be the best way to use this file knowing that converting it or exporting it to a .scn file with scntool hasn't worked?

Thank you!
