Thanks! It's using a convolutional neural network which I minimally adapted from an MNIST tutorial (one of the reasons I picked this project to start with is that there are so many MNIST tutorials for how to do digit recognition out there and it seemed like a good way to dip my toe into ML). Converting it to CoreML after it was trained was really easy. The hardest part was actually creating the dataset and wrestling with pixel buffers to get the image data into a format CoreML liked.
