For Android we have ProGuard that shrinks, optimizes and obfuscates the code.Is there any equivalent for iOS?.

Hello Team, Is there any way we can get the Apple Review team's IPs to whitelist them in our organization's firewall so that the apple review team can access our app and review it?

Our mobile application needs to use the Zscaler app to access the APIs due to security measures. So is there any we can let the apple review team know that they will need to use the Zscaler app for review or is there a way to whitelist their IPs so that they can test using a demo account?
