Obj-C interop: Prevent bridging from Foundation classes?

I have an Obj-C category on NSLocale implementing these readonly properties:

@property (class, nonatomic, nonnull, readonly) NSLocale *searchLocale;
@property (nonatomic, nonnull, readonly) NSString *extendedLanguageCode;

Now when I wanna access it from Swift, I've to write (NSLocale.search as NSLocale).extendedLanguageCode . Is there a way to avoid the casting to NSLocale?

I'm aware I could write a Swift extension like this:

extension Locale {
	var extendedLanguageCode: String {
		(self as NSLocale).extendedLanguageCode

However, that doesn't scale well. I have multiple properties and I'd need such glue code for all of them.

So I was looking for a switch to tell the compiler that for a specific class property it should not apply the bridging from NSLocale to Locale and actually return an NSLocale in Swift.

Any idea how to solve this?
