Convert HTML Text to Normal Text adds an extra Carraige Return in Objective-C

Question

I have a method which would be used to convert the HTML Text to Normal Text.
The issue is that when I pass an HTMl Text, it adds an extra Carriage Return to the Normal Text.

Below is the Method and Sample Text which is causing the issue.

Could someone let me know what am I missing or needs to be done for this?
Appreciate the help.

- (NSString *)flattenHTML {
    NSString *finalString = self;

    if ([self isEqualToString:kSNREmptyString] == NO) {
        NSAttributedString *attributeString = nil;
        NSData *data = [self dataUsingEncoding:NSUnicodeStringEncoding];

        if (nil != data) {
            NSDictionary *encodingDict = [NSDictionary dictionaryWithObject:@(NSUnicodeStringEncoding)
                                                                     forKey:@"CharacterEncoding"];
            attributeString = [[NSAttributedString alloc] initWithHTML:data
                                                    documentAttributes:&encodingDict];
            finalString = [attributeString string];
        }
    }

    return finalString;
}

Sample Text:

What's your initial HTML string? I suspect some paragraph <br> or something like that that adds \n. — Larme
The one that has been specified is the actual HTML String. There is nothing before that. — Rahul Singh
