收到合规通知：Apple Music API/MusicKit违规问题咨询

First, let's anchor this with the exact notification you received from Apple (for full context):

我们写信告知您关于您应用的最新情况。
经重新评估，我们发现您的应用不符合App Store审核指南。具体问题如下：
指南4.5.2 - 设计 - Apple站点与服务
您的应用似乎将Apple Music与广告关联使用。
为解决此问题，请确保Apple Music用户数据未用于广告目的。若您的应用并非有意使用Apple Music，建议移除Apple Music API。
为避免应用在App Store的可用性中断，请在本通知发出一周内提交更新。若未在一周内收到更新，您的应用可能会被下架。

What Apple's 4.5.2 Rule Actually Enforces #

Apple's core requirement here is non-negotiable:

• No Apple Music user data (listening history, account preferences, media library access, etc.) can be tied to advertising—this includes personalized ad targeting, ad optimization, or any indirect correlation between Apple Music data and your ad stack.
• Even accidental integration (via third-party SDKs) counts as a violation if Apple detects a link between Apple Music APIs and ad functionality.

How to Diagnose the Issue (Focused on Ad SDKs) #

Since you suspect an ad SDK is the culprit, let's narrow down the root cause step by step:

1. Audit your ad SDK documentation
   • Check each ad SDK you've integrated to see if any mention Apple Music integration or media data collection for ad targeting. Some SDKs include this by default to "enhance" ad relevance, without clear upfront notice.
2. Search your codebase for Apple Music identifiers
   • Use Xcode's global search (Cmd+Shift+F) to hunt for these keywords:
     • MPMediaLibrary
     • SKCloudServiceController
     • NSAppleMusicUsageDescription (check your Info.plist)
     • Endpoints from api.music.apple.com
   • This will flag direct or indirect references to Apple Music, whether in your own code or embedded SDKs.
3. Inspect your Info.plist for hidden permissions
   • If you see NSAppleMusicUsageDescription listed, that means your app (or an SDK) is requesting access to Apple Music. This is a critical red flag—track down which component added this permission.
4. Capture network traffic during ad loads
   • Use Xcode's Network Inspector or a tool like Charles to monitor traffic when ads display. Look for any requests to Apple Music's API; if an ad SDK is pulling data from there, you'll catch it here.

Fixes to Resolve the Violation #

Once you've pinpointed the issue, here's how to fix it:

• If an ad SDK is the problem:
  • Reach out to the SDK's support team immediately. Ask them to provide a toggle to disable Apple Music data collection, or send you an updated version of the SDK that removes this functionality entirely.
  • If the SDK provider can't or won't resolve it, replace it with a different ad SDK that explicitly states compliance with Apple's 4.5.2 rule.
• Strip all Apple Music-related code and permissions:
  • Delete any Apple Music API calls from your own codebase.
  • Remove the NSAppleMusicUsageDescription entry from your Info.plist (if present).
  • If the SDK includes embedded Apple Music code and you can't get an update, consider stripping those modules (only do this if you're confident it won't break the SDK's core ad functionality).
• Validate before submitting:
  • Recompile your app and test the ad flow thoroughly to ensure no Apple Music interaction remains.
  • Use Xcode's Organizer to validate your archive—this will catch any leftover permissions or API references.

When Submitting Your Update #

In the App Store Connect review notes, clearly outline your fixes to speed up the review process. For example:

"Resolved 4.5.2 violation by removing unintended Apple Music API integration from our ad SDK. Verified no Apple Music user data is used for advertising purposes, and all related permissions have been removed."
