In the meantime, here are some resources that you might find useful...
The slide deck for the webinar. If you missed the webinar, this is a good place to start.
fmEasyAPI. This is everything you need to create the app that I demonstrated today. It includes the sample FileMaker database, fmEasyAPI (a PHP-based app that serves as the API), and the Xojo source code for the iOS app.
And finally, information on another Xojo webinar that we're giving next month can be found here. I'll show you how you can use Xojo to develop iOS apps that make use of Airtable's amazing API. It's being held on August 18th. I hope you'll join us.
