iOS today extension not showing

I'm developing a today extension and it works fine on simulator, but when I run my app on device it doesn't work. App works fine but extension it doesn't show so that I can add it to drop down with other extensions(like it doesn't exists). Can somebody please tell me what I'm doing wrong.

Thanks

Which is the correct extension for iOS app?

An . ipa file is an iOS and iPadOS application archive file which stores an iOS/iPadOS app.

How do I add an extension to an iPhone share?

To add a share extension to your app, open your app's project in Xcode and select File > New > Target from the menu bar. Xcode presents a sheet that contains templates for different kinds of targets. Select the share extension template from the iOS pane and follow the steps in Xcode's interface to add one to your app.

Check if extension deployment target is compatible with your device
