Another Code along session, using AppIntents, WidgetKit and App Intents.  Check out the code which is available at in the Session 10029 folder – https://developer.apple.com/documentation/watchOS-Apps/updating-your-app-and-widgets-for-watchos-10 

Widget Configuration

• AppIntentConfiguration is new in WatchOS 10 and will be used in this project.
• Make sure you check out last years Dive in to App Intents to get started and then review Explore enhancements to App Intents

Timeline Setup

• This holds all the data needs to render a widget on a particular date

Widget Views

• There was significant work on making a nice looking Widget, but for some reason I could not get the previews to show it.  It kept crashing, and then it said there was no preview defined.  Oh well, I can see it in the simulator

Timeline

• Make sure you enter based on date and future date, so that your fill the timeline with relevant data
• Also, setup a AppIntentRecommendation 

Relevance (this will prioritize when our widget should be prioritized on the Smart Stack)

• Updating the relevance information at the right time in your app is key.  This session does a great job of explaining the why of each update in the code.
