# 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 This does not by itself confirm an unpublished source tag or a specific source-level API change.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](https://api.appledb.dev/ios/main.json). Keep beta builds in the separate beta table.
2. **Match the shipped WebKit binary.** Open the same Apple build in [Ravel](https://ravel.dbg.re/browse), 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`.
```swift
import WebKit
let webKitBundleVersion = Bundle(for: WKWebView.self)
.object(forInfoDictionaryKey: "CFBundleVersion") as? String
```
Ravel binary paths:
```text
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`.

## Binary mappings verified in Ravel
These rows are stronger than a release-name match because the OS build and Mach-O UUID are both known.

### iOS
Ravel exposes the binary UUID for these iOS dyld caches, but not the framework `Info.plist`. The `CFBundleVersion` must be captured at runtime before the source mapping can be called exact.

## Current certificate-info crash
| Field | Value |
|---|---|
| macOS | `27.0.1 (26A434)` |
| Crash/Ravel UUID | `70BEE322-37EE-3B22-8012-4F76BA105C29` |
| `CFBundleVersion` | `22625.1.29.11.28` |
| `FULL_VERSION` | `625.1.29.11.28` |
| Candidate source tag | `❓ WebKit-7625.1.29.11.28` — inferred; not public as of 2026-10-06 |
| Result | The shipped binary has the old one-argument `commitCertificateInfo` ABI; the fix is absent. |
The fix landed in `318982@main`. **❓ Unconfirmed:** macOS 27.2 is only a candidate for the first fixed system release; public `WebKit-7625.2.*` source tags are not available yet.
