Answer 1

NSString *str = @"Happy to help you \U0001F431";

NSData *data = [str dataUsingEncoding:NSNonLossyASCIIStringEncoding];
NSString *valueUnicode = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];


NSData *dataa = [valueUnicode dataUsingEncoding:NSUTF8StringEncoding];
NSString *valueEmoj = [[NSString alloc] initWithData:dataa encoding:NSNonLossyASCIIStringEncoding];

_lbl.text = valueEmoj;

SWIFT - 3 OR HIGHER

    let str = "Happy to help you \U0001F431"

    let data : NSData = str.dataUsingEncoding(NSNonLossyASCIIStringEncoding)!
    let valueUnicode : String = String(data: data, encoding: NSUTF8StringEncoding)!

    let dataa   : NSData = valueUniCode.dataUsingEncoding(NSUTF8StringEncoding)!
    let valueEmoj : String = String(data: dataa, encoding: NSNonLossyASCIIStringEncoding)!

SWIFT - 4 OR HIGHER

    let str = "Happy to help you \U0001F431"

    let data : NSData = str.dataUsingEncoding(NSNonLossyASCIIStringEncoding)!
    let valueUnicode : String = String(data: data as Data, encoding: String.Encoding.utf8)!

    let dataa   : NSData = valueUnicode.data(using: String.Encoding.utf8)! as NSData
    let valueEmoj : String = String(data: dataa as Data, encoding: String.Encoding.nonLossyASCII)!

You can use ⌃ ⌘ Space shortcut to show the symbols panels and just insert the emoji you're looking for directly without unicode:

lbl.text = @"Happy to help you 😺";

(just copy the code above to Xcode if you browser doesn't show the emoji)

Swift 3.0 solution update given by @Bhavesh Nayi

    let data =  txtMessage.text!.data(using: .nonLossyASCII)
    let emojiString = String.init(data: data!, encoding: .utf8)

and Send it to Chat Server as a

    let data = message.message.data(using: .utf8)
    let emoji = String.init(data: data!, encoding: .nonLossyASCII)

and Then Show emoji to UILablel

Answer 5

In case of swift 2.3 or lower

let textViewData : NSData = textViewString.dataUsingEncoding(NSNonLossyASCIIStringEncoding)!
let valueUniCode : String = String(data: textViewData, encoding: NSUTF8StringEncoding)!

let emojData   : NSData = valueUniCode.dataUsingEncoding(NSUTF8StringEncoding)!
let emojString : String = String(data: emojData, encoding: NSNonLossyASCIIStringEncoding)!

In Case of Swift 3.0 or higher

let textViewData = textViewString.data(using: .nonLossyASCII)
let valueUniCode = String.init(data: textViewData!, encoding: .utf8)!

let emojData   = valueUniCode.data(using: .utf8)
let emojString = String.init(data: emojData, encoding: .nonLossyASCII)
