Navigating Apple’s New Privacy Manifest Requirements for iOS apps
The landscape of mobile app privacy is constantly evolving, and apple is leading the charge with significant changes to its App store submission guidelines. Developers must now proactively address how their apps – and the third-party SDKs they integrate - handle user data. This article provides a comprehensive guide to Apple’s new privacy manifest and signature requirements, introduced at WWDC23, ensuring you understand the implications and can prepare for the upcoming deadlines. Understanding these changes is crucial for maintaining App Store compliance and building user trust.
understanding the Core Changes: Privacy Manifests & API Usage
Apple’s initiative centers around two key components: privacy manifests and the declaration of approved reasons for API usage. Traditionally, developers have had limited visibility into the data practices of the SDKs embedded within their applications. This lack of transparency posed risks to user privacy and made it arduous to ensure compliance with regulations like GDPR and CCPA.

Privacy manifests are essentially declarations that SDK providers must include with their software, detailing the types of data they collect and how that data is used. Developers, in turn, are required to declare why their app needs access to certain APIs - specifically those requiring “approved reasons” – within their own privacy manifest files. This creates a chain of accountability and transparency, empowering both developers and users.
Key Dates & Implementation Timeline
Apple has implemented these changes in phases. Here’s a breakdown of the critical dates:
* March 13th (Ongoing): App Store Connect now flags apps that are missing approved reasons for APIs requiring them. Developers receive email notifications along with in-App Store Connect alerts. This is a warning period, allowing time for remediation.
* May 1st (Enforcement Date): Submitting a new app or app update without the required approved reasons for listed APIs will result in rejection. This is the hard deadline.
* Ongoing: New third-party SDKs added to the list of commonly used SDKs will also be subject to these manifest and signature requirements.
Pro tip: Don’t wait until May 1st! Begin auditing your app and its sdks now to identify any potential issues and ensure a smooth transition.
Identifying APIs Requiring Approved Reasons
the APIs requiring approved reasons fall into categories related to sensitive user data, such as location tracking, contact access, and microphone/camera usage. Apple provides detailed documentation outlining the specific APIs and the acceptable reasons for their use: Approved Reasons for Using required Reason APIs.
These reasons are not open-ended; developers must select from a predefined list,ensuring a consistent and verifiable justification for data access. Examples include legitimate business needs, security purposes, or user-requested functionality.
Implementing Privacy Manifests: A Step-by-Step Guide
- Audit Your SDKs: Identify all third-party SDKs integrated into your app.
- Check SDK Compliance: Verify that each SDK provider has published a privacy manifest. Contact them if it’s missing.
- Analyze API Usage: Determine which APIs your app uses that require approved reasons.
- Declare Approved Reasons: Add the appropriate reasons to your app’s privacy manifest file (
PrivacyInfo.xcprivacy). Apple provides tools and documentation to assist with this process. - Test Thoroughly: Ensure your app functions correctly with the updated privacy manifest.
- Submit for Review: Submit your app to the App Store and address any feedback from the review team.
the Role of SDK Signatures
Beyond privacy manifests, Apple now requires signatures for commonly used third-party SDKs. This adds another layer of security, verifying the authenticity and integrity of the SDK code. SDK providers must digitally sign their SDKs, and developers must ensure they are using signed versions.This
