objc_enumerateClasses

TypeScript
objc_enumerateClasses(fromImage?: ObjCEnumerationImage, matchingNamePrefix?: (string) | null, conformingTo?: (string) | null, subclassing?: (string) | null): ObjCClassList
Swift declaration
func objc_enumerateClasses(fromImage: ObjCEnumerationImage = .machHeader(#dsohandle), matchingNamePrefix: String? = nil, conformingTo: Protocol? = nil, subclassing: AnyClass? = nil) -> ObjCClassList

Enumerates classes, filtering by image, name, protocol conformance and superclass. - Parameter fromImage: The image to search; defaults to the caller's image. - Parameter matchingNamePrefix: If specified, a required prefix for the class name. - Parameter conformingTo: If specified, a protocol to which the enumerated classes must conform. - Parameter subclassing: If specified, a class which the enumerated classes must subclass. - Returns: A `Sequence` of classes that match the search criteria.
