Just recently, in one our iOS apps, we’ve had to implement a system to check if strings had emojis in order to parse them, and it is as simple as :

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
return true
default:
continue
}
}
return false
}

}
