iOS error "Embedded binary is not signed with the same certificate as the parent app"

The embedded binary is referring to a widget that you are deploying alongside with your app.

In your case, you are not signing your widget with any Signing Identity (since your error says "Not Code Signed").

To resolve this, go to your Project file, find your widget's target, and under the Build Setting tab, find the Code Signing Identity value. Choose the same code signing identity that you are using for your main app's target.

You will also need to create and configure a provisioning profile specifically for your widget when you want to release it.

Swift 5 . Simple way in my case check this screen shot i am done
