KVC does not work with typedefs

justwow.m

#import <Foundation/Foundation.h>

typedef NSObject Foobar;
@interface Klass : Foobar
@property Foobar *baz; 
@end
@implementation Klass
@end

int main(int argc, char *argv[]) {
    @autoreleasepool {
        Klass *obj = [Klass new];
        
        NSLog(@"%s", @encode(typeof(obj.baz))); // Gets @encoded like `struct { NSObject } *`
        
        obj.baz = @123;
        NSLog(@"%@", obj.baz);
        
        [obj setValue:@321 forKey:@"baz"]; // Crash
        NSLog(@"%@", [obj valueForKey:@"baz"]); // Crash
    }
}

Use @compatibility_alias;
e.g. @compatibility_alias Foobar NSObject
