Cant seem to get this one on the quiz

I believe it should be

  • (id) initWithSinger:(NSString *)singer { return [[self alloc] initWithSinger:singer]; }

Am i missing something?

I believe you should be returning self. If you look below you can see that you can't return the method in itself. That is what you are doing.

return self;

-(id) initWithTitle:(NSString *)title
{
    self = [super init];
    if (self) {
        self.title = title;
        self.author = nil;
        self.thumbnail = nil;
    }

    return self;
}

+(id) blogPostWithTitle:(NSString *)title
{
    return [[self alloc] initWithTitle:title];
}
