iOS UITextView ignoring newline char from JSON Response

I need to display some data from a JSON Webservice in my iOS App inside a UITextView which is multiline however when I use the String on the textview the new lines do not work.

Here is the code I am using: 

// Data Value from JSON = testing the data value \r\n Another \n liine maybe?
NSString *responseDataString = [dictRequestorDetails objectForKey:@"data"];
txtWorkflowDetails.text = responseDataString;

When I execute this code the UITextField shows

testing the data value \r\n Another \n liine maybe?

However If I type in the string like

// Data Value from JSON = testing the data value \r\n Another \n liine maybe?
NSString *responseDataString = [dictRequestorDetails objectForKey:@"data"];
txtWorkflowDetails.text = @"testing the data value \r\n Another \n liine maybe?";

The line breaks then work in the TextView

Swift 4:

let stringForUITextView = originJsonString.replacingOccurrences(of: "\\n", with: "\n")

Just followed this post: Adding a line break to a UITextView

I updated my JSON feed to output the new lines like

testing the data value \nAnother \nmline maybe?

And then in my code ran; 

responseDataString = [responseDataString stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"];

Is txtWorkflowDetails set to allow Line Breaks (e.g. Word Wrap)?

You can process the string first and replace all occurrences of \n with \n

NSString *newString = [responseDataString stringByReplacingOccurrencesOfString:@"\n" withString:@"\\n"];
