I'm not sure exactly why this became an issue in Swift 6.3.

The warning is 'warning: expected member name or initializer call after type name on macOS 26.5'. it would appear that Swift cannot uniquely? correctly? resolve the base type for Self.CodingKeys anymore.

Specifically setting the full base type (QRCode.LogoTemplate.CodingKeys.self) resolves the issue.
