CIImage, CIDetector - how to find other objects in images other than faces

Question

Is there anyway to find other objects in images without having to integrate other 3rd party libraries like openCV and write all the algorithms myself..

i.e. if i wanted to locate anything an in image that looks like a door? or locate anything that looks like a number 1...9?

Is there support to pass in a 2D shape image, and a photo, and have IOS try to find that shape in the photo file?

With the iPhoneX being able to detect faces for FaceID, surely there will be lots of advancements in the image detection iOS libraries...Anyone know? – Zacharie
