Hi,
Maybe this has been asked before but I couldn't find it.
I would like to be able to give visibility of non-generic subclass of a
generic class to obj-c. Is there any limitation of the compiler knowing
that the type of the non-generic type is closed, to generate a compatible
version for obj-c?
Code Example:
class SwiftSuperType<T: NSObjectProtocol> : NSObject {
}
class NonGenericClass2: SwiftSuperType<NSObject> {
}
Or with a obj-c super class:
@interface ObjcSuperType<T: id<NSObject>> : NSObject
@end
class NonGenericClass: ObjcSuperType<NSObject> {
}
Actual Behaviour:
Non-generic classes are not visible in obj-c. If adding the @objc notation
we get the following error.
Actual error message:
Generic subclasses of '@objc' classes cannot have an explicit '@objc'
attribute because they are not directly visible from Objective-C
regards,
