Actually, this started crashing after working initially. Xcode 26 beta 3 has same problem.

It would be great if we could reference code snippets in unit tests that are known to work and compile. Having sample code that doesn't actually compile is a very common - and avoidable - problem. Case in point: The code found here: https://developer.apple.com/documentation/authenticationservices/public-private_key_authentication/supporting_passkeys doesn't actually compile because the API has changed. let platformProvider = ASAuthorizationPlatformPublicKeyCredentialProvider(relyingPartyIdentifier: "example.com") ...should be... let platformProvider = ASAuthorizationPlatformPublicKeyCredentialProvider("example.com") Other platforms such as .NET's SandCastle Help File Builder support this capability, btw.
