Crashed when a property with class Keyword

[Sunny-zhao]

Define A property like
@Property (nonatomic, class, readonly) NSString *UUID;
In @implementation

• (NSString *)UUID { return @"xxxx"; }

Oops, something went wrong...
AppledocException: Failed merging @Property xxxxxxxx.UUID to +[xxxxxxxx UUIDt]; method type doesn't match!

I'm having the same issue. Is there any update on this?

can pass err but no support to docset content about class keyword property
