chore: declare the file-timestamp required-reason API in a privacy manifest - #1354
Conversation
📝 SummarySummary by CodeRabbit
WalkthroughThe SDK adds an Apple privacy manifest at Priority: ⬇️ Low Change: Other Merge Risk: 🟡 Moderate · up to The incomplete declaration may cause privacy compliance or App Store review issues for apps uploading document-picker files, so it should be corrected before merge.

Declares the SDK's behavior on Apple platforms: no tracking, no data collected on its own behalf, and one required-reason API. Uploads read a file's size to set `Content-Length` before streaming it. The size comes from `FileManager.attributesOfItem(atPath:)`, which also returns `NSFileCreationDate` / `NSFileModificationDate` and stats the file, so it falls in Apple's file-timestamp category whichever key the caller reads. Declared with `C617.1` — the files involved are the temp file the transport spools and whatever the host app points us at to upload. Without the declaration, apps embedding this SDK can be sent ITMS-91053 on submission with nothing from us to satisfy it. SDK-1805 assumed Keychain and `UserDefaults` forced this. Neither does — Keychain is not a required-reason API, and `UserDefaults` appears nowhere in the package, nor do boot-time, disk-space or active-keyboard APIs. The real trigger was the file-size reads, which the issue did not mention. The manifest lives in `Helpers` because every product links it, so the bundle is present however a consumer imports us. Part of SDK-1805.

💡 Result:
<search_synthesis>
The identifiers C617.1 and 3B52.1 correspond to approved reasons for using the File Timestamp API (NSPrivacyAccessedAPICategoryFileTimestamp) within an Apple app's privacy manifest [1][2]. When your app or an included third-party SDK accesses file timestamps, metadata, or file sizes, you must declare this usage in your privacy manifest file (PrivacyInfo.xcprivacy) under the NSPrivacyAccessedAPITypes key [2][3]. You must select the approved reason(s) that accurately reflect your app's actual use of the API [2][3]. According to Apple's official documentation for NSPrivacyAccessedAPICategoryFileTimestamp: - C617.1: Declare this reason to access the timestamps, size, or other metadata of files inside the app container, app group container, or the app’s CloudKit container [1]. - 3B52.1: Declare this reason to access file timestamps, size, or metadata for files or directories that the user has explicitly granted access to, such as via a file picker (e.g., UIDocumentPickerViewController) [1]. In your privacy manifest, this should be structured as an array of dictionaries within the NSPrivacyAccessedAPITypes key, where you pair the API category with the appropriate reason codes [4][2]. If you find that your app or a third-party SDK is flagging these APIs, you must ensure the declared reasons match the functionality. If you are not using these APIs for one of the approved purposes, you should remove the code using them or find an alternative approach [2][5].

Declare the reason for user-granted file URLs.
HTTPBody(fileURL:) passes any caller-supplied file URL to FileManager.attributesOfItem(atPath:) to read its size. A caller can provide a document-picker URL outside the app, app-group, or CloudKit containers. Apple defines 3B52.1 for metadata access to files the user specifically granted access to, while C617.1 covers files inside those containers.
Add 3B52.1 alongside C617.1. The initializer supports both file locations, so replacing C617.1 or restricting the public input would not match the current API. Without 3B52.1, the manifest does not accurately describe all supported uses and may cause privacy compliance or App Store review issues.

The required-reason API
Uploads read a file's size to set
Content-Lengthbefore streaming it. That size comes fromFileManager.attributesOfItem(atPath:), which also returnsNSFileCreationDate/NSFileModificationDateand stats the file — so it falls in Apple's file timestamp category whichever key the caller actually reads. Three live paths do this:HTTPBody(fileURL:), the transport's spooled temp file, andMultipartFormData's file parts.Declared with
C617.1— the files involved are the temp file the transport spools into the app container, and whatever the host app points us at to upload.Without this, apps embedding the SDK can be sent ITMS-91053 on submission with nothing from us to satisfy it.
Correcting the issue
SDK-1805 assumed Keychain and
UserDefaultsforced a manifest. Neither does — Keychain is not a required-reason API, andUserDefaultsappears nowhere in the package, nor do boot-time, disk-space or active-keyboard APIs. The real trigger is the file-size reads, which the issue didn't mention.An earlier revision of this PR declared an empty
NSPrivacyAccessedAPITypeson that mistaken basis. That was worse than shipping nothing: an empty array is an affirmative claim that the SDK touches no required-reason APIs. Fixed.Placement
The manifest lives in
Helpersbecause every product links it, so the bundle is present however a consumer imports us — and the file-size calls live in bothHelpersandStorage, so a single shared declaration is also the accurate one.Testing
plutil -pconfirmsNSPrivacyAccessedAPITypesparses as an array of dicts — the first draft had the keys unwrapped, which lints as valid plist but is the wrong shape for Apple's reader.Stack
