com.apple.developer.on-demand-install-capable
A Boolean value that indicates whether a bundle represents an App Clip.
Discussion
Adding an App Clip target to your project as described in Creating an App Clip with Xcode enables a capability called On Demand Install Capable for the App Clip target.
When you code-sign your full app, Xcode embeds the App Clip in the full app and applies the com.apple.developer.on-demand-install-capable entitlement. Because of this behavior, the App Clip’s .entitlements file doesn’t include this entitlement if you open the file in Xcode’s Project navigator.
To see the entitlement in the .entitlements file, first archive the full app, then export the App Clip for distribution as described in Distributing your App Clip. Next, open the Terminal app and run codesign -d --entitlements :- /path/to/ExampleApp.app/AppClips/ExampleAppClip.app.
