Also, depending on the iOS version you’re running, you could be able to just load the ARKit framework using the load_framework method in the objc_module.
import objc_util objc_util.load_framework('ARKit') #do stuffThe work @Brun0oO did, if I’m not mistaken, just makes using ARKit a little easier with Pythonista. It still uses objc_util in the background to do everything, so merging your code with Bruno’s should be a simple process.
