For the release of macOS 10.13 High Sierra, we are working on supporting CoreML framework in FileMaker and Xojo. Here is my test database to detect :
While macOS 10.13 is not ready for a few weeks, we can already download the beta versions of macOS and Xcode and play with it. You can use a model quite easy as you see in the Core ML presentation from WWDC 2017. With just a few lines in a script we load a model, setup source image and run it though the neural network to classify the picture. You can get sample models from Apple's Machine Learning website.
The plugin will be available later this month with the macOS release.
