Start a self signed certificate https server， Will it be rejected by the AppStore auditor?

In my application, I need to load the html5 code downloaded to the local computer through the https server embedded in the application. These local html5 codes are small programs developed by some front-end developers. My https server will only load these small programs locally, so I use a self-signed certificate. The code to access the small program is like this: "https://localhost:12345/MiniAppA", ""https://localhost:12345/MiniAppB". ，My applet container will use different certificate verification rules based on the domain name. I want to know if this technical form will be rejected by AppStore reviewers?

        completionHandler(NSURLSessionAuthChallengeUseCredential, credential);
    } else {
        completionHandler(NSURLSessionAuthChallengePerformDefaultHandling, nil);
    }
