Answer 1

You can try this (Swift 5).

Create String extension:

extension String {

    func containsEmoji() -> Bool {
        for scalar in unicodeScalars {
            if !scalar.properties.isEmoji { continue }
            return true
        }

        return false
    }

}

Then use it in UITextFieldDelegate like this:

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
     if string.containsEmoji() { return false }
     return true
}
