Now with the new release of iOS 10, for the following emojis it doesn't work:

Emojis

The following code snippet is tried and tested for both iOS 9 and iOS 10:

extension String {

    var containsEmoji: Bool {
        for scalar in unicodeScalars {
            switch scalar.value {
            case 0x1F600...0x1F64F, // Emoticons
            0x1F300...0x1F5FF, // Misc Symbols and Pictographs
            0x1F680...0x1F6FF, // Transport and Map
            0x2600...0x26FF,   // Misc symbols
            0x2700...0x27BF,   // Dingbats
            0xFE00...0xFE0F,   // Variation Selectors
            0x1F910...0x1F918, // New Emoticons
            0x1F1E6...0x1F1FF, // Flags
            0x1F980...0x1F984,
            0x1F191...0x1F19A,
            0x1F201...0x1F202,
            0x1F232...0x1F23A,
            0x1F250...0x1F251,
            0x23E9...0x23F3,
            0x23F8...0x23FA,
            0x1F170...0x1F171,
            0x1F17E,
            0xA9,
            0xAE,
            0x2122,
            0x2328,
            0x3030,
            0x1F0CF,
            0x1F18E,
            0x1F9C0:
                return true
            default:
                continue
            }
        }
        return false
    }
}

Create a String extension in your app as mentioned above.

And can be used like this:

if string.containsEmoji {
    // Do operations here
}
