Apple OS to WebKit release mapping

Read this first

This is the lookup table for DuckDuckGo's supported range: macOS 12.3+ and iOS 15.0+. It includes every stable minor and patch release recorded by AppleDB through 2026-10-06.

Missing version numbers are intentional: Apple did not publish a stable release with that number.

Evidence labels:

Label Meaning
exact/tag ✅ Confirmed: Apple published an OS-specific WebKit source tag. The full five-part source version is known.
exact/binary ✅ Confirmed binary mapping: the OS build, WebKit UUID and CFBundleVersion were matched in Ravel. This does not by itself confirm an unpublished source tag or a specific source-level API change.
❓ unconfirmed/train Only the Safari/WebKit release family is known. Apple has not published an exact OS-specific source tag; .* is intentional.

An OS marketing version alone is not enough for crash forensics. Hardware-specific OS builds can differ, and macOS can receive Safari/WebKit updates separately. For an exact answer, match OS build + WebKit UUID + CFBundleVersion.

Research and table-update procedure

  1. Identify the OS release. Record the marketing version and every stable Apple build from AppleDB. Keep beta builds in the separate beta table.
  2. Match the shipped WebKit binary. Open the same Apple build in Ravel, select the correct architecture, and record the WebKit Mach-O UUID. For crash research, require an exact UUID match with the crash image.
  3. Read CFBundleVersion. Use Ravel metadata when present or read it on the target OS with the Swift snippet below. Strip the platform prefix to obtain FULL_VERSION: iOS uses 8; macOS uses 17 for macOS 12, 18 for 13, 19 for 14, 20 for 15, 21 for 26, and 22 for 27.
  4. Resolve and inspect the source. Check the exact public tag WebKit-7<FULL_VERSION>; for version 612 and early 613, also check Safari-<FULL_VERSION>. Inspect the API or symbol at that tag. main, Safari Technology Preview, or a release-train match alone does not prove inclusion in a system release.
  5. Update the row with its evidence. Use exact/tag when the exact public tag is verified. Use exact/binary when build + UUID + CFBundleVersion are verified but the tag is unavailable, and prefix the inferred source tag with ❓. If only the release family is known, retain .* and use ❓ unconfirmed/train.
import WebKit

let webKitBundleVersion = Bundle(for: WKWebView.self)
    .object(forInfoDictionaryKey: "CFBundleVersion") as? String

Ravel binary paths:

macOS: /System/Library/Frameworks/WebKit.framework/Versions/A/WebKit
iOS:   /System/Library/Frameworks/WebKit.framework/WebKit

iOS mapping

iOS production bundle versions use prefix 8: CFBundleVersion = 8 + FULL_VERSION.
