How to remove \n from string in Swift?

Question

Here is my string and I want to remove some characters from string. My code is below

"{  \"userpass\" : \"\",  \"apikey\" : \"=\",  \"deviceid\" : \"\",  \"username\" : \"\"}"

and I want to convert into this format.

{ 
    "userpass" : "",
    "username" : "",
    "deviceid" : "",
    "apikey" : "="
}

How to remove \ from string to make JSON string proper?

This string is pretty-printed JSON. You should **not** try to decode it by doing character replacement/parsing but by using proper JSON methods. — Eric Aya, Jul 13 '16 at 11:32

This is json in String response if you want to get dictionary from that try this, Here str is your string

let str = "{  \"userpass\" : \"\",  \"apikey\" : \"=\",  \"deviceid\" : \"\",  \"username\" : \"\"}"
let data = str.dataUsingEncoding(NSUTF8StringEncoding)
do {
    let dic = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as! NSDictionary
    print(dic)
}
catch let e as NSError {
    print(e.localizedDescription)
}

In objective-c

NSString *stringWithoutSpaces = [yourString 
   stringByReplacingOccurrencesOfString:@" " withString:@""];

All special characters with in string must use extra \ (escape sequence) to recognize the actual value    

 [string stringByReplacingOccurrencesOfString:@"\\n" withString:@""];
    or string.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())

hope you will be clear

While this code may answer the question, providing additional context regarding how and/or why it solves the problem would improve the answer's long-term value. – HiDeoo Jul 13 '16 at 12:44
