The value backing this should probably be Optional<Seconds> instead of Optional<unsigned> so that one can specify a fraction of a second. That's what is suggested in the Web IDL. >> Source/WebKit/UIProcess/API/Cocoa/_WKWebAuthenticationPanelForTesting.h:39 >> ++ (WebCore::PublicKeyCredentialCreationOptions)convertToCoreCreationOptionsWithOptions:(_WKPublicKeyCredentialCreationOptions *)options WK_API_AVAILABLE(macos(WK_MAC_TBA), ios(WK_IOS_TBA)); > > I think it would be better if we just exposed the things we want to query in an ObjC API, like exposing the icon instead of a WebCore C++ structure through an ObjC API. The purpose is to test if the objc options are translated well into the C++ options. So, that's why. The underneath functionality once the options are set correctly is well tested with layout tests. So it will be redundant to do a full set of integrated tests to test the correctness of the options. That's why I think unit tests like this will make more sense. >> Tools/TestWebKitAPI/Tests/WebKitCocoa/_WKWebAuthenticationPanel.mm:1449 >> + RetainPtr<_WKPublicKeyCredentialCreationOptions> options = [[_WKPublicKeyCredentialCreationOptions alloc] initWithRp:rp.get() user:user.get() pubKeyCredParams:pubKeyCredParams]; > > adoptNS or this is a memory leak.

I can see that being useful when there is a need to keep the binding between the C++ objects and the objc objects. But for what this API does, it's not necessary to do that. Also, all the fields in the response are needed to be copied and convert into NS types given they are all binaries. I can do a follow up to separate this file into different ones. >> Source/WebKit/UIProcess/API/Cocoa/_WKWebAuthenticationPanel.mm:494 >> + _WKAuthenticatorAttestationResponse* result = [[_WKAuthenticatorAttestationResponse alloc] initWithRawId:[NSData dataWithBytes:data.rawId->data() length:data.rawId->byteLength()] extensions:nil attestationObject:[NSData dataWithBytes:data.attestationObject->data() length:data.attestationObject->byteLength()]]; > > Memory leak.

Especially little objects that use ObjC-generated ivars unlike the rest of the API objects in WebKit. Alright, I have separated those interfaces into separate files. However, I'm not going to introduce APIObject for those interfaces given they are not practically useful here. >> Source/WebKit/UIProcess/API/Cocoa/_WKWebAuthenticationPanel.h:192 >> +- (instancetype)init NS_UNAVAILABLE; > > new should also be NS_UNAVAILABLE here.

Making this change would cause a compiler failure if we add something in the future and forget to update, and it also doesn't require default constructor to be called. I think writing it in this way is more clear than having a helper that just has one line of return code. >> Source/WebKit/UIProcess/API/Cocoa/_WKWebAuthenticationPanel.mm:512 >> + handler(nil, [NSError errorWithDomain:WKErrorDomain code:WKErrorUnknown userInfo:nil]); > > Can we use the exception data instead of just reporting an unknown error? This patch is already pretty big. I would like to address that in <rdar://problem/71509485> given I might need to introduce some objc enum to do the translation.
