r=me, although you may want to get another look of someone more familiar with ObjC :)

If this property is provided, it is assumed that 'filenames' are not real file paths on the session host's filesystem, and this binary data will be used instead." }

Shouldn't these be `"type": "string"`?

Should we add more detail, like "The parameter 'filenames' contains a non-string value at index ${i}."?

> Source/WebKit/UIProcess/Automation/WebAutomationSession.cpp:1261

Ditto (>1252).

> +        Optional<String> localFilePath = platformGenerateLocalFilePathForRemoteFile(filename, fileData);

`auto`?

> +        if (!localFilePath.hasValue())

You can drop the `hasValue`.  It's the same as `operator bool`.

> Source/WebKit/UIProcess/Automation/WebAutomationSession.cpp:1265
> +            SYNC_FAIL_WITH_PREDEFINED_ERROR_AND_DETAILS(InternalError, "The remote file could not be saved to a local temporary directory.");

Ditto (>1252).

> +Optional<String> WebAutomationSession::platformGenerateLocalFilePathForRemoteFile(const String& remoteFilePath, const String& base64EncodedFileContents)

Don't include the parameter names if they aren't used (or surround them in an inline comment) (or use an `UNUSED_PARAM`).

> Source/WebKit/UIProcess/Automation/cocoa/WebAutomationSessionCocoa.mm:64
> +    NSString *temporaryDirectory = FileSystem::createTemporaryDirectory(@"WebDriver");

I'd move these below the `if (!fileContents)` check, as they aren't needed before that.

> Source/WebKit/UIProcess/Automation/cocoa/WebAutomationSessionCocoa.mm:65
> +    NSData *fileContents = [[NSData alloc] initWithBase64EncodedString:base64EncodedFileContents options:0];

Should we `adoptNS` or retain/release this?

It may be worth mentioning that this uses the `lastPathComponent` of the `remoteFilePath` as the filename, just so it's a bit clearer why "/a/b/c.txt" might get moved to only be "WebDriver/c.txt".

Good catch!

It'll be WebDriver-XXXXXXXX where the Xs are randomized.
