Does you physical device have Shortcuts app installed? I noticed that if you remove the Shortcuts app that it seems like the App Intent doesn't get registered.

I believe you need to include your application name in the phrase. That was what seemed to fix it for me. Try this: AppShortcut(intent: ShowTodayTasks(), phrases:["Show today tasks in \(.applicationName)", "Show my tasks today in \(.applicationName)"])

Have you had any luck here? I'm running into similarly issues. AppShortcut(intent: AskClipDish(), phrases: [ "Ask \(.applicationName) a question", "Ask \(.applicationName) for help", "Ask \(.applicationName)", "Tell \(.applicationName) \(\.$questionForClipDish)" ]) When I trigger with Ask ClipDish, I'm prompted to choose between Messages and ClipDish With I trigger with Tell ClipDish question, Safari opens.

Except that's not 100% accurate. That is the behavior in iOS. However, you can exclude 3rd party extension activities when you build for macOS (built for iPad) or Catalyst.
