With XCode Version 26.1.1 (17B100) the project gets errors:

public extension AttributeScopes {
struct CoreTextAttributes: AttributeScope {
let rubyAnnotation: RubyAnnotationAttribute
let foundation: FoundationAttributes
#if canImport(SwiftUI)
let swiftUI: SwiftUIAttributes
#endif
}

var coreText: CoreTextAttributes.Type { CoreTextAttributes.self }

}

Extensions must not contain stored properties (for CoreTextAttributes.Type)

extension CTRubyPosition: CaseIterable {
public static var allCases: [CTRubyPosition] = [.before, .after, .interCharacter, .inline]
}

Extension declares a conformance of imported type 'CTRubyPosition' to imported protocol 'CaseIterable'; this will not behave correctly if the owners of 'CoreText' introduce this conformance in the future
