Answer 1

One possible cause for this is not having set the NSSupportsLiveActivities property in your App target's Info.plist.

Even if you have it set in your Widget Extension make sure it's set in your App target.

It should look like this in Xcode:

Looks like you also need to add NSSupportsLiveActivities to app's info.plist in addition to widget's info.plist And xcode 14.1 also seems to have issues if your profile has access to app containers :-( – Fissi

Answer 2

You will have to add Supports Live Activities to the apps info.plist in addition to the widget's info.plist

Answer 3

In my case I have this error when trying to start a Live Activity from my app.

Error requesting Live Activity The operation couldn’t be completed. (com.apple.ActivityKit.ActivityInput error 0.)

What I did was:

1. Go to Info -> Add Supports Live Activities

2. Go to Signing & Capabilities, add Push Notification capability

Answer 4

Please make sure that you are using iPhone with 16.2 above OS versions. When you will run a live activity on iPad it shows the same error log Because it's only supported on iPhones.
