# Mapping Apple OS builds to WebKit source releases
|
# Apple OS to WebKit release mapping
|
||||||
|
|
||||||
## Purpose
|
## Read this first
|
||||||
|
|
||||||
This document explains how to map a WebKit crash on macOS or iOS to:
|
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**.
|
||||||
|
|
||||||
1. the exact Apple OS build;
|
Missing version numbers are intentional: Apple did not publish a stable release with that number.
|
||||||
2. the exact system WebKit binary by Mach-O UUID;
|
|
||||||
3. its `CFBundleVersion` and WebKit `FULL_VERSION`;
|
|
||||||
4. the closest public WebKit source tag;
|
|
||||||
5. the presence or absence of a source change.
|
|
||||||
|
|
||||||
The DuckDuckGo Apple browsers currently support macOS **12.3+** and iOS **15.0+**. The deployment targets are defined in `macOS/Configuration/Common.xcconfig` and `iOS/DuckDuckGo-iOS.xcodeproj/project.pbxproj` in the Apple browsers repository.

||||||
## Short answer
|
| Label | Meaning |
|
||||||
|
|---|---|
|
||||||
|
| `exact/tag` | Apple published an OS-specific WebKit source tag. The full five-part source version is known. |
|
||||||
|
| `exact/binary` | The OS build, WebKit UUID and `CFBundleVersion` were matched in Ravel. |
|
||||||
|
| `train` | The Safari/WebKit release family is known, but Apple has not published an exact OS-specific source tag. `.*` is intentional. |
|
||||||
|
|
||||||
Use this chain for an exact mapping:
|
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`**.
|
||||||
|
|
||||||
```text
|
## iOS mapping
|
||||||
OS version + OS build
|
|
||||||
-> WebKit Mach-O UUID from the crash report
|
|
||||||
-> matching binary and UUID in Ravel
|
|
||||||
-> WebKit CFBundleVersion from the OS or app telemetry
|
|
||||||
-> remove the platform SYSTEM_VERSION_PREFIX
|
|
||||||
-> WebKit FULL_VERSION
|
|
||||||
-> public source tag or release branch
|
|
||||||
-> inspect the released code for the fix
|
|
||||||
```
|
|
||||||
|
|
||||||
An OS major version identifies only a **WebKit release train**. It does not identify the exact WebKit revision because Apple updates WebKit in OS point and security releases.
|
iOS production bundle versions use prefix `8`: `CFBundleVersion = 8 + FULL_VERSION`.

## Version fields
|
|
||||||
|
|
||||||
| Field | Example | Meaning |
|
### iOS 15
|
||||||
|---|---:|---|
|
|
||||||
| OS version | `macOS 27.0.1` | Marketing version |
|
|
||||||
| OS build | `26A434` | Exact Apple OS build; use this in Ravel |
|
|
||||||
| Mach-O UUID | `70BEE322-...` | Exact WebKit binary identity for one architecture |
|
|
||||||
| `CFBundleVersion` | `22625.1.29.11.28` | System framework build version |
|
|
||||||
| `SYSTEM_VERSION_PREFIX` | `22` | Platform/OS prefix added by Apple's production build |
|
|
||||||
| WebKit `FULL_VERSION` | `625.1.29.11.28` | Release version without the system prefix |
|
|
||||||
| Source tag | `WebKit-7625.1.29.11.28` | Candidate public source release |
|
|
||||||
| HTTP User-Agent | `AppleWebKit/605.1.15` | Frozen compatibility token; not usable for this mapping |
|
|
||||||

macOS 26.6 and 26.6.1 contain the same WebKit binary: both UUID and `CFBundleVersion` match.
|
### iOS
|
||||||
|
|
||||||
### iOS examples
|
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.
|
||||||
|
|
||||||
Ravel identifies iOS WebKit binaries and UUIDs, but its dyld-cache page does not expose the framework `Info.plist` value. Read `CFBundleVersion` at runtime or from an extracted IPSW before claiming an exact source release.

|
||||||
|
|
||||||
### 1. Read the OS build and WebKit UUID
|
## Exact lookup procedure
|
||||||
|
|
||||||
From an Apple crash report, record the OS version/build and the WebKit image UUID. Compare UUIDs without case or dashes, and match the architecture.
|
1. Read the OS build and WebKit image UUID from the crash report.
|
||||||
|
2. Open that build in Ravel and verify the same UUID and architecture.
|
||||||
```bash
|
3. Read `CFBundleVersion` from `Bundle(for: WKWebView.self)`.
|
||||||
rg 'OS Version:|WebKit.*<' crash-report.crash
|
4. Remove the platform prefix to obtain `FULL_VERSION`.
|
||||||
```
|
5. Resolve the source tag and inspect the released code.
|
||||||
|
|
||||||
### 2. Find the binary in Ravel
|
|
||||||
|
|
||||||
Use the OS build and the correct binary path:
|
|
||||||
|
|
||||||
```text
|
|
||||||
macOS: /System/Library/Frameworks/WebKit.framework/Versions/A/WebKit
|
|
||||||
iOS: /System/Library/Frameworks/WebKit.framework/WebKit
|
|
||||||
```
|
|
||||||
|
|
||||||
Ravel URL pattern:
|
|
||||||
|
|
||||||
```text
|
|
||||||
https://ravel.dbg.re/binary?build=<OS_BUILD>&domain=dyld_cache&path=<URL_ENCODED_BINARY_PATH>
|
|
||||||
```
|
|
||||||
|
|
||||||
The Ravel UUID must equal the crash-report UUID. A matching version string without a matching UUID is weaker evidence.
|
|
||||||
|
|
||||||
### 3. Read `CFBundleVersion`
|
|
||||||
|
|
||||||
From app code on either platform:
|
|
||||||
|
|
||||||
```swift
|
```swift
|
||||||
import WebKit
|
import WebKit
|
||||||
@@ -152,148 +405,36 @@ let webKitBundleVersion = Bundle(for: WKWebView.self)
|
|||||||
.object(forInfoDictionaryKey: "CFBundleVersion") as? String
|
.object(forInfoDictionaryKey: "CFBundleVersion") as? String
|
||||||
```
|
```
|
||||||
|
|
||||||
On macOS, it can also be read without app changes:
|
Ravel paths:
|
||||||
|
|
||||||
```bash
|
|
||||||
defaults read /System/Library/Frameworks/WebKit.framework/Resources/Info CFBundleVersion
|
|
||||||
```
|
|
||||||
|
|
||||||
For iOS, log the runtime value on a test device or include it in crash/pixel metadata. Do not infer an exact iOS value from the same-numbered macOS release.
|
|
||||||
|
|
||||||
### 4. Remove `SYSTEM_VERSION_PREFIX`
|
|
||||||
|
|
||||||
Apple production builds concatenate the prefix and the WebKit version:
|
|
||||||
|
|
||||||
```text
|
```text
|
||||||
CFBundleVersion = SYSTEM_VERSION_PREFIX + FULL_VERSION
|
macOS: /System/Library/Frameworks/WebKit.framework/Versions/A/WebKit
|
||||||
|
iOS: /System/Library/Frameworks/WebKit.framework/WebKit
|
||||||
```
|
```
|
||||||
|
|
||||||
| Platform | OS | Prefix |
|
Modern source tags use `WebKit-7<FULL_VERSION>`. The 612 and early 613 trains use `Safari-<FULL_VERSION>`.
|
||||||
|---|---|---:|
|
|
||||||
| iOS | All supported versions | `8` |
|
|
||||||
| macOS | 12 | `17` |
|
|
||||||
| macOS | 13 | `18` |
|
|
||||||
| macOS | 14 | `19` |
|
|
||||||
| macOS | 15 | `20` |
|
|
||||||
| macOS | 26 | `21` |
|
|
||||||
| macOS | 27 | `22` |
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|
||||||
```text
|
|
||||||
22625.1.29.11.28 - prefix 22 -> 625.1.29.11.28
|
|
||||||
```
|
|
||||||
|
|
||||||
### 5. Resolve the public source release
|
|
||||||
|
|
||||||
For modern release trains, candidate tags use:
|
|
||||||
|
|
||||||
```text
|
|
||||||
WebKit-7<FULL_VERSION>
|
|
||||||
```
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|
||||||
```text
|
|
||||||
625.1.29.11.28 -> WebKit-7625.1.29.11.28
|
|
||||||
```
|
|
||||||
|
|
||||||
The 612 train is an older naming exception:
|
|
||||||
|
|
||||||
```text
|
|
||||||
612.1.27.* -> Safari-612.1.27.*
|
|
||||||
```
|
|
||||||
|
|
||||||
Check exact public tags and release branches:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
git ls-remote --tags https://github.com/WebKit/WebKit.git 'WebKit-7625.1.29*'
|
|
||||||
git ls-remote --heads https://github.com/WebKit/WebKit.git 'safari-7625*'
|
|
||||||
```
|
|
||||||
|
|
||||||
An adjacent tag is only a bound, not an exact match. Apple may publish a binary before publishing the corresponding source tag.
|
|
||||||
|
|
||||||
### 6. Verify the fix in released source
|
|
||||||
|
|
||||||
Inspect the changed code in the candidate tag. This is stronger than checking one commit SHA because Apple may cherry-pick the change under a different SHA.
|
|
||||||
|
|
||||||
For the certificate-info crash discussed below:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
git show <TAG>:Source/WebKit/UIProcess/WebFrameProxy.h \
|
|
||||||
| rg 'commitCertificateInfo'
|
|
||||||
```
|
|
||||||
|
|
||||||
Old signature:
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
void commitCertificateInfo(const URL&);
|
|
||||||
```
|
|
||||||
|
|
||||||
Fixed signature from `318982@main`:
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
void commitCertificateInfo(const URL&, bool hasCertificateInfo);
|
|
||||||
```
|
|
||||||
|
|
||||||
### 7. When the exact source tag is unavailable
|
|
||||||
|
|
||||||
Record the evidence level explicitly:
|
|
||||||
|
|
||||||
1. UUID + `CFBundleVersion`: exact binary and release version are known.
|
|
||||||
2. Symbols or disassembly: a specific ABI or behavior can be proven in the binary.
|
|
||||||
3. Reproduction on the exact OS build: the bug can be proven present or absent.
|
|
||||||
|
|
||||||
Safari Technology Preview is a separate build. Its version does not prove the version of system WebKit.

The crash on macOS 27.0.1 maps as follows:
|
| 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` — not public as of 2026-10-06 |
|
||||||
|
| Result | The shipped binary has the old one-argument `commitCertificateInfo` ABI; the fix is absent. |
|
||||||
|
|
||||||
```text
|
The fix landed in `318982@main`. macOS 27.2 is a candidate for the first fixed system release, but public `WebKit-7625.2.*` source tags are not available yet.
|
||||||
macOS: 27.0.1 (26A434)
|
|
||||||
Crash UUID: 70BEE322-37EE-3B22-8012-4F76BA105C29
|
|
||||||
Ravel UUID: 70BEE322-37EE-3B22-8012-4F76BA105C29
|
|
||||||
CFBundleVersion: 22625.1.29.11.28
|
|
||||||
Prefix: 22
|
|
||||||
FULL_VERSION: 625.1.29.11.28
|
|
||||||
Candidate tag: WebKit-7625.1.29.11.28
|
|
||||||
```
|
|
||||||
|
|
||||||
The exact `.11.28` source tag is not public as of 2026-10-06; `.11.27` is public. The crash symbol and the `WebKit-7625.1.29` source family both show the old one-argument signature. Therefore the fix is absent from macOS 27.0.1.
|
## Data sources and maintenance
|
||||||
|
|
||||||
Ravel identifies macOS 27.2 beta binaries as `625.2.4.1`, `625.2.5.11.1`, and `625.2.7.1`. Public `WebKit-7625.2.*` tags are not available as of 2026-10-06. The fix landed in `318982@main` and Safari Technology Preview 251, so macOS 27.2 is a candidate for the first fixed system release, but source inclusion is not yet proven.

Current pixels do not include the exact system WebKit `CFBundleVersion`. The HTTP User-Agent cannot fill this gap because Apple returns the frozen `AppleWebKit/605.1.15` compatibility token.
|
|
||||||
|
|
||||||
Add one field to relevant crash and WebKit failure telemetry:
|
|
||||||
|
|
||||||
```text
|
|
||||||
webkit_build=22625.1.29.11.28
|
|
||||||
```
|
|
||||||
|
|
||||||
Populate it from `Bundle(for: WKWebView.self).CFBundleVersion`. This makes OS-build-to-WebKit correlation deterministic on both macOS and iOS.
