Does filemaker go support the maps app? Can you integrate it into a database?
You can't embed other apps inside of your own app as it breaks iOS's sandboxing rules.
However, you can launch the maps app using the Open URL script step from FileMaker, following the URL specifications from apple:
Note that since there is an http:// prefix to the links in that documentation, I believe it will open via safari.
If you need to embed maps into your app directly, there's a number of techniques to do so without apple maps. Say for instance ProMaps from Seedcode: https://www.seedcode.com/promaps/ which uses google maps.
There an issue using http:// so change http to maps in your url. "maps://maps.apple.com/?address="
