在快速将 JSON 数据转换为字符串时无法正确打印

Question

I am converting the (NS)Data to a string in Swift (2.2 atm) coming from a service call and I want to display it in the console. so

let s = String(data: data!, encoding: NSUTF8StringEncoding)
print(s)

what I see has escaped character which is fairly useless to read

Optional("{\"assets\":{\"err-fc2264112130e2c90bef0887b4367bb7\":{\"errors\": ...

is there a clever way to have it show the JSON without the \\" and missing the carriage returns. I thought of running the NSJSONSerialization twice (from data to foundation back to data with formatting on and then to string). I can do that but I wonder if there is some less irritating way.

Answer 1

You convert data to string, so the result you have is corrent, it's optional string.

If you want to get json result, you should just serialize the data.

simply,

if let json = NSJSONSerialization.JSONObjectWithData(data!, 
    options: NSJSONReadingOptions.MutableContainers, error: nil) {
    print(json)
}

Answer 2

Try below solution:

let myStr = String(data: data!, encoding: .utf8)!
print(myStr as AnyObject)
