Thank you very much for your response. I'm still encountering the same issue and would like to ensure that I'm not making any mistakes. I have set the Network Extensions in the Apple Developer Identity section. Then I found these two configuration files for the Entitlements: App-ios.entitlements Extension-ios.entitlements I added the following lines to both files: <key>com.apple.developer.networking.networkextension</key> <array> <string>app-push-provider</string> </array> Then, I cleaned the project (Product -> Clean) and archived it (Product -> Archive). The build succeeds as shown in the screenshot below: When I click on "Distribute", I encounter the same two errors again. I'm at a loss to understand what's wrong.

Actually I don’t know what you mean. I cannot find app-push-provider in the portal. I added app-push-provider in the two entitlements files. The problem can be there. Can you point me to the right section of the dev portal? Thanks!
