What's new in Core ML

To say this year has been massive for API and framework updates would be underselling WWDC 2019. Core ML has been no exception. So far with Core ML 2 we saw some amazing updates and that made on device training amazingly simple. However, there was still a lot to be desired and if you wanted to implement newer models like YOLO you needed to drop down to Metal and do a lot of leg work to get a model up and running. Now we have Core ML 3 and honestly outside of optimization alone I'm not too sure why you would need to drop down to metal after this new update.
