Question:

Today’s test brought a low version of iPhone. I ran the project with it and reported the following errors
dyld: Library not loaded: /System/Library/Frameworks/Network.framework/Network
Referenced from: /var/containers/Bundle/Application/CD697C3E-135B-4A33-BA7B-D95D33E24070/巨折.app/巨折

Solution:

Follow the prompts and go to Build Phases -> Link Binary With Libraries and add Network.framework

After running it still reports the same error, then you need to go to Link Bnary With Libraries and set Network to Optional.
