No valid 'aps-environment' entitlement string found for application on app store

I fixed this issue like this:

• Go to Xcode "Preferences"
• Go to "Accounts" tab
• Select my Apple ID and click "View Details"
• Click on the arrow on the bottom left corner to refresh
• Click "Done"

And try again!

I fix this problem by enabling push notification capability.

Click on .xcodeproj -> Capabilities -> Enable Push Notification
