Xcode-9 OR iOS 11 - replacing double quote with \" not working

Question

As I am replacing the double quote with escape char as mentioned in below in code. The Same code works fine in iOS 10.x and not working in iOS 11.

NSString *searchStr = [searchBar.text stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""];

NSString *searchInput = [[NSString alloc] initWithFormat:@"{\"@type\": \"com.xyz.rest.find.SearchQuery\",\"value\": \"%@\"}", searchStr];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:[searchInput dataUsingEncoding:NSUTF8StringEncoding]];

Any leads will be appreciated !!!!

Thanks in advance

@ThreeCoins: When I search for "Cool"(with double quote) it should get value as "\"Cool\'" in iOS 10 whereas in iOS 11 it gets ""Cool"" which doesn't give expected results. Eg: iOS 10 : Input search Str: “Cool” NSString *searchStr = [searchBar.text stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""]; o/p: “\“Cool\”” iOS 11: NSString *searchStr = [searchBar.text stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""]; o/p: “”Cool”” It’s not even replacing double quote with any other character. — Bhavesh Patel, Nov 06 '17 at 10:55

This may be because of smart punctuation introduced in iOS 11. Please check below link.
