iOS纯IPv6网络下Google Map无法加载，App遭Apple拒审求助

Hey there, I’ve dealt with this exact issue a few times, so let’s break down how to get past this rejection and get your app back on track.

First, let’s clear up the Google Console confusion: Google Maps APIs natively support IPv6—there’s no separate toggle to enable it in the Cloud Console. That option doesn’t exist because support is baked in, so your missing setting isn’t the problem here. The issue is almost certainly on your app’s side.

Here are the steps to diagnose and fix the problem:

• Update your Google Maps SDK to the latest version
  Older versions of the Maps SDK for iOS had occasional IPv6 compatibility gaps. Head to your dependency manager (CocoaPods, Swift Package Manager, etc.) and pull the most recent stable release. This alone fixes most IPv6-related loading issues.

• Audit your app’s network code for IPv4-only assumptions
  Check if your app uses any hardcoded IPv4 addresses, or network libraries that don’t support IPv6. For example, if you’re using custom networking code, make sure you’re using getaddrinfo() instead of deprecated functions like gethostbyname() which only handle IPv4. Also, avoid filtering network results to only IPv4 addresses—let the system handle both protocols.

• Verify your ATS (App Transport Security) settings
  Apple requires ATS to be configured correctly, and this can impact IPv6 connectivity. Ensure your Info.plist includes the necessary exceptions for Google Maps domains (like *.googleapis.com, *.gstatic.com) if needed, but more importantly, make sure you haven’t set any ATS flags that restrict IPv6 traffic. The default ATS settings should work, but double-check if you’ve added custom rules that might block it.

• Test locally in an IPv6-only environment
  To reproduce the issue Apple is seeing, create an IPv6-only network on your Mac:

  1. Go to System Preferences > Sharing > Internet Sharing
  2. Select your primary internet source (e.g., Ethernet) and share to Wi-Fi
  3. Click the "Wi-Fi Options" button, go to the "TCP/IP" tab
  4. Set "Configure IPv6" to "Link-local only"
  5. Connect your iOS device to this Wi-Fi network and test your app’s Maps functionality.
     This will let you confirm if the issue is reproducible and verify when your fix works.

• Check for proxy or VPN interference in your test environment
  Sometimes local proxies or VPNs can mask IPv6 issues. Make sure you’re testing without any network filters enabled to replicate the clean IPv6 environment Apple uses for review.

Once you’ve implemented these fixes, resubmit your app with a note to the review team explaining that you’ve resolved the IPv6 compatibility issue for Google Maps, and mention that you’ve tested in an IPv6-only environment to confirm the fix works.
