As discovered by Scotty Jackson, there are new Reminders actions in the Shortcuts app in iOS 18 developer beta 2. The new actions are โCreate Reminderโ and โOpen Any List,โ both of which still seem to be in testing.
Create Reminder and Open Any List are both updated versionsโbut distinct fromโtheir respective counterparts โAdd New Reminderโ and โOpen Reminders Listโ (and โOpen Smart List).
New Reminders actions

Create Reminder has more options than Add New Reminder, including new fields for List Section (within the Target List) and Subtasks. Plus, the action changes the Alert field to separate All-Day and Due Date fields, losing the โWhen Messaging,โ โWhen I Leave,โ and โWhen I Arriveโ options in the process as well โ it remains to be seen if these will be restored somehow. Thereโs also a new โAssign Reminderโ field that does not current return any results in my testing.

Open Any List provides a single variable for โAny Listโ which lets you pick a specific List from Reminders and, when run, open it โ this appears to be a replacement for the separate โOpen Reminders Listโ action (which came first) and the โOpen Smart Listโ action (which came later), combining the two under a more-logical single action going forward. However, this action is also oddly-implemented in both its name and the fact that it includes an โOpen When Runโ toggle thatโs not functional and should be built-in to the action, not available as a toggle.
Neither has the Parameter Summary feature implemented, so both actions do not read like a natural sentence with a parameter inline and instead hide it below the fold โ this goes against Appleโs own recommendations, so it appears that both actions are an earlier implementation and hopefully will change in future betas.
App Intents for Apple teams too
Overall, seeing updates to these Reminders actions is a good sign for the Shortcuts ecosystem, as itโs the first signal that Apple is updating their native Shortcuts actions with App Intents-based replacements in iOS 18.
Since the inception of many of these actions in Workflow when Shortcuts was a third-party app, many actions have been built on longstanding external-facing developer APIs (hence actions like โGet Upcoming Remindersโ) and then later custom intents from within teams at Apple โ they either stayed the same as the Workflow actions, or got piece-by-piece updates for new features each year like Tags in Reminders.
However, as is the nature of intents development, Apple also has tried not to break anything or remove features that are being used in existing shortcuts โ but rather than deprecating actions over time, they either have been updated-in-place, added as separate actions (like โOpen Smart Listโ), or simply not implemented in Shortcuts at all.
Now, it appears that weโre seeing the first evidence of an Apple team seeding new actions in betas, hopefully testing and iterating on them, and then likely replacing the Workflow- and custom intents-era actions with modern App Intents actions that can be extended with new features more easily and updated going forward.
More to come
I hope Apple eventually replaces all the native Shortcuts actions from the Workflow days with full-featured, modern App Intents actions for all of their apps, as well as adopt their own recommendation that โEverything in your app should be an App Intent.โ
Thatโs because developers will take absolutely notice when Apple leads the way, and, furthermore, many Shortcuts users have been waiting (somewhat) patiently for about 7 years for Apple to take the promise of Workflow and run with it for their own apps in a big way.
Apple Intelligence and App Intents for third-party developers will be fantastic, but Appleโs own teams need best-in-class integrations as well โ hopefully these Reminders actions are a sign of more to come.
Iโll update this post if these Reminders get updates in future releases, and check back for more action coverage after each new developer beta this summer.
