How to send message to contact in Whatsapp from iOS App - Swift

Question

I am trying to send a message from my iOS app developed in Swift to a Whatsapp contact. But the specific contact does not get opened, instead all my contacts in whatsApp open up.

My code so far -

func messageViaWhatsApp (sender: AnyObject) {
   let messageBody = "Hello"
    let whatsURL = "whatsapp://send?text=\(messageBody)"
    let whatsAppURL  = NSURL(string: whatsURL.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!)
    if UIApplication.sharedApplication().canOpenURL(whatsAppURL!)
    {
        UIApplication.sharedApplication().openURL(whatsAppURL!)
    }
    else
    {
        let alert = UIAlertView(title: "Sorry", message: "Your device does not have whatsApp installed ", delegate: nil, cancelButtonTitle: "OK")
    }

}

Thanks for your help. XCode - 8.0, Swift 2.3

What specific contact? You didn't specified a contact in your code. And if I remember well, WhatsApp removed some time ago the option to choose the contact, but maybe they reinstalled id. — Larme, Oct 05 '16 at 10:14

For security purpose Apple doesn't allow you to send to a particular contact.

Try this....

let urlWhats = "whatsapp://send?phone=***********&text=***"

var characterSet = CharacterSet.urlQueryAllowed
characterSet.insert(charactersIn: "?&")

 if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: characterSet){

if let whatsappURL = NSURL(string: urlString) {
                if UIApplication.shared.canOpenURL(whatsappURL as URL){
                    UIApplication.shared.openURL(whatsappURL as URL)
                }
                else {
                    print("Install Whatsapp")

                }
            }
        }

Note:Country code (Ex:+91) is mandatory to open mobile number Chat

Note: Add url scheme in info.plist

<key>LSApplicationQueriesSchemes</key>
 <array>
 <string>whatsapp</string>
</array>
